When it comes to healthy eating, you will be hard-pressed to find a health care provider who isn’t a fan of the tip to “eat more fish.” But, as a registered dietitian, I often remind clients that not every fish is considered a nutritional powerhouse. And while some types of fish are perfectly fine to eat frequently, others should be consumed with caution.

So what are the healthiest fish options you should be stacking on your plate, and what should you be skipping? Read on for the seafood scoop.

What are the health benefits of eating fish?

Many varieties of fish, particularly cold-water oily fish like salmon, are rich in omega-3 fatty acids, “healthy” fats that support heartbrain and eye health.

Furthermore, fish is a source of high-quality protein while being lower in saturated fat, making it a smart choice for those seeking to maintain a balanced diet. It’s also packed with important nutrients such as vitamin D, selenium and iodine, which support immune function, bone health and thyroid regulation.

Regular fish consumption has been associated with a reduced risk of conditions such as coronary heart disease. Additionally, some data links fish consumption to improved mood and a reduced risk of depression among certain populations.

Despite the health benefits associated with regular fish consumption, many Americans aren’t eating enough. While the Dietary Guidelines for Americans recommends eating 8 ounces, or about two servings, of seafood (which includes fish and shellfish) per week, it notes that nearly 90% of Americans don’t meet that target.

What’s the healthiest fish to eat?

While most fish are excellent additions to a healthy and balanced diet, some stand out as “best” choices for various reasons. Here are four to try.

Salmon

“One of the healthiest fish is salmon, as it is high in health-promoting omega-3 fats,” Melissa Mitri, a registered dietitian, nutrition writer and owner of Melissa Mitri Nutrition, tells Yahoo Life. “Salmon is very nutrient-dense, providing a generous amount of protein, healthy fats, vitamins and minerals in a small portion.” That includes vitamins such as B12 and D and minerals like selenium, which support immune function and bone health.

It’s worth noting that wild salmon contains more protein and potassium — which is great for managing blood pressure — than farm-raised varieties. “Salmon is also low in mercury, a heavy metal that can be toxic to the nervous system and various organs in large amounts,” adds Mitri.

Farmed trout

Farmed trout is a healthy choice due to its rich content of omega-3 fatty acids, which support heart health and reduce inflammation,” according to Mascha Davis, a registered dietitian nutritionist and author of Eat Your Vitamins. “It is also a great source of high-quality protein, [which is] essential for muscle growth and repair. Furthermore, it provides important micronutrients, including vitamin D and selenium, which contribute to overall well-being.”

Davis notes that there have been concerns about fish farming, also known as aquaculture. But she points to “significant advances” in the practice that have made it “more sustainable and cleaner.” Says Davis: “In the U.S., numerous farmed trout operations grow fish in fresh spring water, provide high-quality feed and ensure ethical care for the fish.” One easy way to ensure your farmed fish choices are responsibly raised and free from antibiotics is to look for an Aquaculture Stewardship Council (ASC) label on your product.

Sardines

Sardines are also rich in omega-3 fatty acids. They are a low-mercury fish option thanks to being small and low on the food chain, which limits their mercury accumulation compared with larger predatory fish. This makes them a safer choice for regular consumption, especially for vulnerable populations such as pregnant women and young children.

Choosing sardines with bones (they are soft and edible!) provides an extra boost of calcium, contributing to bone health.

Atlantic mackerel

Mackerel contains essential nutrients such as omega-3 fatty acids. It is also a good source of protein, B vitamins and minerals such as selenium and potassium.

Why eat Atlantic mackerel in particular? Compared with other types of mackerel, such as king mackerel, Atlantic mackerel has a notably lower mercury concentration, making it a more health-conscious option.

What fish should I limit?

By and large, most fish, particularly oily varieties, is great for you. But there are considerations that should be made when it comes to consuming fish raw, or eating a type with a high mercury level. (And, of course, anyone with a shellfish allergy should avoid anything within that group.)

High-mercury fish

Mercury is a heavy metal that can accumulate in fish tissue. Consuming high levels of it can lead to serious health issues, including neurological and developmental problems. According to the Food and Drug Administration, limiting mercury is crucial for children and anyone who might become pregnant or breastfeeding.

Some high-mercury fish to avoid or limit include:

  • Shark
  • Swordfish
  • Marlin
  • King mackerel
  • Tilefish
  • Bigeye tuna
Raw fish

Consuming raw fish can pose health risks due to potential contamination with parasites, bacteria or viruses often eliminated through cooking. These pathogens can lead to foodborne illnesses when consumed. Certain individuals, including pregnant women, young children, older adults and people with weakened immune systems, should avoid eating raw fish due to their increased susceptibility to illness.

However, healthy people can generally eat raw fish safely if it is sushi grade, sourced from reputable suppliers and handled properly to prevent contamination. Moreover, certain fish, like salmon and tuna, are deemed safer to consume raw after being frozen at specific temperatures to kill parasites.

Eating too much fish

Eating fish is generally considered healthy. But consuming too much fish can lead to potential health risks, primarily due to the accumulation of mercury and other environmental contaminants in certain fish types. It is important to maintain a balanced intake by choosing fish lower in mercury, like salmon, sardines and trout, and following dietary guidelines to ensure a healthy, varied diet.

How can I get more fish into my diet?

Ready to reap the health benefits of eating fish? Here are some tips to help you hit that two-servings-a-week guidance. (And for anyone who doesn’t like the taste of fish, Mitri suggests starting with a “more neutral-tasting fish” like cod and going from there.)

  • Start with breakfast: Don’t limit fish to dinner. Add smoked salmon or trout to your morning scrambled eggs or avocado toast.
  • Experiment with tacos: Fish tacos are an easy and delicious way to add more fish to your diet. You can use grilled, baked or even canned fish as a filling.
  • Snack on fish: Sliced salmon with cream cheese on whole-grain crackers or tuna-stuffed cucumber boats provide a tasty and nutritious alternative to traditional snacks.
  • Include fish in soups and stews: This is an excellent way to enhance flavor and nutrition. Make a seafood chowder or add chunks of fish like cod or haddock to vegetable soup for a hearty meal.
  • Upgrade your sandwiches: Try a grilled fish sandwich with your favorite topping, or make a tuna melt for a quick and satisfying meal.

To maximize the health benefits of fish, opt for cooking methods like baking, grilling or steaming rather than frying your fish, which can add unhealthy fats. When seasoning or cooking, limit the use of butter and use healthier alternatives like olive oil or lemon juice to enhance flavor. Consider the overall composition of your meal by balancing your fish with a variety of colorful vegetables and whole grains, ensuring a well-rounded intake of essential nutrients and fiber.

Officials confirm first fatal case of mosquito-borne virus in nearly two decades: ‘A stark reminder’

Officials confirm first fatal case of mosquito-borne virus in nearly two decades: ‘A stark reminder’

Juliana Marino – September 3, 2024

County officials in the Bay Area confirmed a death related to a mosquito-borne disease for the first time in nearly 20 years, according to a report published by the San Francisco Chronicle.

What’s happening?

Officials in Contra Costa County announced that a resident died from West Nile virus in July. It was the first death from West Nile in Contra Costa since 2006.

Mosquitoes can carry West Nile virus after feeding on an infected bird. Though many cases of West Nile virus do not lead to any symptoms, some patients experience a fever, headache, body aches, and vomiting.

“West Nile virus is the leading cause of mosquito-borne disease in the continental United States,” according to the Centers for Disease Control and Prevention.

While most cases of West Nile virus are not fatal, officials in Contra Costa viewed the death as a wake-up call.

“We are deeply saddened by the loss of a Contra Costa County resident to West Nile virus,” Contra Costa Mosquito and Vector Control District general manager Paula Macedo told the Chronicle. “This tragic event serves as a stark reminder of the importance of protecting ourselves from mosquito bites and supporting community efforts to control mosquito populations.”

Why is this concerning?

Increasing global temperatures have created more ideal conditions for disease-spreading mosquitoes. The tragic death of the Contra Costa resident is a reminder to take necessary precautions to prevent mosquito bites, especially during summer months.

Using insect repellent and wearing loose-fitting clothing that covers your arms and legs are ways you can protect yourself from bug bites.

What’s being done about West Nile in the Bay Area?

Moving toward a more sustainable future to keep the planet’s temperatures in balance not only helps protect the environment but also global health. Simple actions to reduce pollution causing Earth to warm at an accelerated rate include switching to LED light bulbs and unplugging appliances when they aren’t in use.

In Contra Costa, officials are still investigating the cause of the disease, per the Chronicle. While they have not provided updates on where the infection happened, they have detected additional cases of West Nile virus in a bird and five chickens, according to district spokesperson Nola Woods.

NH man fights for life with 3 mosquito viruses, including EEE

Paul Burton – September 3, 2024

KENSINGTON, N.H. – A New Hampshire man is fighting for his life because of a mosquito bite. Fifty-four-year-old Joe Casey of Kensington has tested positive for three mosquito-borne viruses, including eastern equine encephalitis (EEE) and West Nile Virus.

“He’s my brother. It’s very difficult, especially because it’s from a mosquito,” his sister-in-law Angela Barker told WBZ-TV, fighting back tears. “He was positive for EEE, for West Nile, and St. Louis Encephalitis, but the CDC, the infectious disease doctors, they don’t know which one is making him this sick.”

Barker said Casey started to feel sick back in early August. He now has swelling in the brain and is barely able to communicate at Exeter Hospital.National & World NewsLatest U.S. and global stories

“Terrifying and gut-wrenching”

“My brother-in-law is not a small man, and to see someone that you love be as sick as he is and not be able to talk, to move, to communicate for over three weeks is terrifying and gut-wrenching,” Barker said.

Casey and his wife Kim have four children. They believe he will have a long road to recovery ahead of him. His family has set up an online fundraising page and they’ve received an outpouring of support from the community.

“It could happen to anybody”

“Joe is going to have to go a long-term care and patient rehabilitation, that’s going to be 24-hour care, and really want to get the word out to help this incredible family,” Barker said. “He just got bit by a mosquito and it could happen to anybody.”

Last week, 41-year-old Steven Perry of Hampstead, N.H., died after contracting EEE.

The New Hampshire Department of Health and Human Services said Kensington has had at least one mosquito pool test positive for EEE. The town has sent out postcards notifying residents and the threat level has been raised to high.

Casey’s family wants people to be careful.

“Be safe, cover up, wear bug spray. It can happen to anybody, and that’s the scariest thing. Be careful and take proper precautions,” Barker said.

On the COVID ‘Off-Ramp’: No Tests, Isolation or Masks

Jason Moyer was days away from a family road trip to visit his parents when his 10-year-old son woke up with a fever and cough.

COVID-19?

The prospect threatened to upend the family’s plans.

“Six months ago, we would have tested for COVID,” said Moyer, 41, of Ohio. This time they did not.

Instead, they checked to make sure the boy’s cough was improving and his fever was gone — and then set off for New Jersey, not bothering to tell the grandparents about the incident.

In the fifth summer of COVID, cases are surging, and the Centers for Disease Control and Prevention has reported “high” or “very high” levels of the virus in wastewater in almost every state. The rate of hospitalizations with COVID is nearly twice what it was at this time last summer, and deaths — despite being down almost 75% from what they were at the worst of the pandemic — are still double what they were this spring.

As children return to schools and Labor Day weekend travel swells, the potential for further spread abounds. But for many like Moyer, COVID has become so normalized that they no longer see it as a reason to disrupt social, work or travel routines. Test kit sales have plummeted. Isolation after an exposure is increasingly rare. Masks — once a ubiquitous symbol of a COVID surge — are sparse, even in crowded airports, train stations and subways.

Human behavior is, of course, the reason that infections are soaring. But at some point, many reason, we need to live.

“I no longer even know what the rules and recommendations are,” said Andrew Hoffman, 68, of Mission Viejo, California, who came down with respiratory symptoms a few weeks ago after his wife had tested positive for COVID. He skipped synagogue, but still went to the grocery store.

“And since I don’t test, I can’t follow them,” he said.

Epidemiologists said in interviews that they do not endorse a lackadaisical approach, particularly for those spending time around older people and those who are immunocompromised. They still recommend staying home for a couple of days after an exposure and getting the newly authorized boosters soon to become available (despite the poor turnout during last year’s round).

But they said that some elements of this newfound laissez faire attitude were warranted. While COVID cases are high, fewer hospitalizations and deaths during the surges are signs of increasing immunity — evidence that a combination of mild infections and vaccine boosters are ushering in a new era: not a post-COVID world, but a postcrisis one.

Epidemiologists have long predicted that COVID would eventually become an endemic disease, rather than a pandemic. “If you ask six epidemiologists what ‘endemic’ means, exactly, you’ll probably get about 12 answers,” said Bill Hanage, associate director of the Center for Communicable Disease Dynamics at Harvard T.H. Chan School of Public Health. “But it certainly has a sort of social definition — a virus that’s around us all the time — and if you want to take that one, then we’re definitely there.”

Certain threats remain clear. For vulnerable groups, the coronavirus will always present a heightened risk of serious infection and even death. Long COVID, a multifaceted syndrome, has afflicted at least 400 million people worldwide, researchers recently estimated, and most of those who have suffered from it have said they still have not recovered.

But the CDC director, Dr. Mandy Cohen, called the disease endemic last week, and the agency decided this year to retire its five-day COVID isolation guidelines and instead include COVID in its guidance for other respiratory infections, instructing people with symptoms of COVID, RSV or the flu to stay home for 24 hours after their fever lifts. The updated guidelines were an indicator that, for most people, the landscape had changed.

Hanage defended the hard-line mandates from the early years of the pandemic as “not just appropriate, but absolutely necessary.”

“But,” he said, “it is just as important to help people onto an off-ramp — to be clear when we are no longer tied to the train tracks, staring at the headlights barreling down.”

The absence of stringent guidelines has left people to manage their own risks.

“I don’t bother testing myself or our kids for COVID,” said Sarah Bernath, 46, a librarian on Prince Edward Island in Canada. “My husband doesn’t test himself either. Knowing if it’s COVID wouldn’t change whether I stay home or not.”

In some social circles, diverging choices can make for uncomfortable dynamics.

Debra Cornelius, 73, of Carlisle, Pennsylvania, stayed home from a recent indoor party because she learned that several other guests — a family of five — had returned from vacation and tested positive for COVID three days before the gathering, but still planned to attend.

“They said, ‘Oh, it’s like a bad cold, we wouldn’t stay home for a cold,’” she said. “I think people’s attitudes have changed considerably.”

But for countless others, attitudes haven’t changed at all. Diane Deacon, 71, of Saginaw, Michigan, said she tested positive for COVID three days into a trip to Portugal with her two adult daughters. She isolated herself for five days before flying home wearing a mask.

“A number of people asked me, ‘Why did you test? You could have carried on with your vacation,’” she said.

For Deacon, it was about remembering the refrigerated morgue trucks of 2020 and anticipating the vulnerable people she might see on her flight home — people in wheelchairs, or people on oxygen, she said.

“I’m trying to avoid a moral judgment of people who make other choices,” she said. “To me, it was inconvenient and it was unfortunate, but it was not a tragedy.”

In a Gallup poll this spring, about 59% of respondents said they believed the pandemic was “over” in the United States, and the proportion of people who said they felt concerned about catching COVID has been generally declining for two years. Among people who rated their own health positively, almost 9 in 10 said they were not worried about getting infected.

That could be, at least partly, a result of personal experience: About 70% of people said they had been through a COVID infection already, suggesting that they believed they had some immunity or at least that they could muscle through it again if need be.

If the Olympics were any barometer, the rest of the world seems to have exhaled as well. In Tokyo in 2021, there were daily saliva samples, plexiglass dividers between cafeteria seats and absolutely no live spectators; the arenas were so empty that coaches’ voices echoed. In Beijing in 2022, under China’s zero-tolerance policy, conditions were much the same.

But in Paris last month, the organizing committee for the 2024 Olympics offered no testing requirements or processes for reporting infections, and so few countries issued rules to their athletes that the ones that did made news.

There were high-fives, group hugs, throngs of crowds and plenty of transmission to show for it. At least 40 athletes tested positive for the virus, including several who earned medals despite it — as well as an unknowable number of spectators, since French health officials (who had once enforced an eight-month-long nightly COVID curfew) did not even count.

In the United States, about 57% of people said their lives had not returned to prepandemic “normal” — and the majority said they believed it never would. But the current backdrop of American life tells a different story.

The years-old social-distancing signage is faded and peeling from the floors of an indoor market in Los Angeles. Hand-sanitizer dispensers at amusement parks have dried up. The summer camp hosted by Chicago’s Lincoln Park Zoo requires children to bring a face covering — not to protect other children, but the animals.

Michael Osterholm, the director of the Center for Infectious Disease Research and Policy at the University of Minnesota, said the newfound complacency can as much be attributed to confusion as to fatigue. The virus remains remarkably unpredictable: COVID variants are still evolving much faster than influenza variants, and officials who want to “pigeonhole” COVID into having a well-defined seasonality will be unnerved to discover that the 10 surges in the United States so far have been evenly distributed throughout all four seasons, he said.

Those factors, combined with waning immunity, point to a virus that still evades our collective understanding — in the context of a collective psychology that is ready to move on. Even at a meeting of 200 infectious disease experts in Washington this month — a number of whom were older than 65 and had not been vaccinated in four to six months — hardly anybody donned a mask.

“We’ve decided, ‘Well, the risk is OK.’ But nobody has defined ‘risk,’ and nobody has defined ‘OK,’” Osterholm said. “You can’t get much more informed than this group.”

Asked about how the perception of risk has evolved over time, Osterholm laughed.

$15 million Ohio State study takes aim at molecule at the heart of Long COVID

$15 million Ohio State study takes aim at molecule at the heart of Long COVID

Samantha Hendrickson, Columbus Dispatch – August 14, 2024

COVID-19 is here to stay, and for some, that means symptoms last months, even years after developing the little-understood Long COVID — but a team at the Ohio State University has received millions to find out more.

The National Institutes of Health (NIH) awarded $15 million over the next five years to fund the university’s efforts, including developing new ways to treat COVID-19 and to further understanding of why Long COVID happens and how to fend it off.

The Centers for Disease Control and Prevention estimates that millions of adults and children have suffered — and continue to — suffer from Long COVID.

Dr. Amal Amer, center with glasses, stands with fellow Ohio State University researchers, who have been granted $15 million over five years to study Long COVID. The research is personal for Amer, who suffered from Long COVID herself.

The disease can be present for as short as three months, but can also last years after someone is first infected. It’s defined as a chronic condition that occurs after a COVID-19 infection with a wide range of debilitating symptoms such as severe fatigue, brain fog, heart and lung problems, bodily pain or exacerbating already existing health issues, all of which can impact someone’s daily life.

“It’s just unacceptable, you can’t just let that happen,” said Dr. Amal Amer, a professor of microbial infection and immunity at OSU and a principal investigator in the project, “We have to understand it, and if somebody, not just us, anybody, happens to have a clue or the beginning of the story, we have to follow it.”

Tiny creatures lead to big discoveries

This massive undertaking started with simple mice and a single molecule.

An OSU study published in 2022 found that mice infected with COVID-19 reacted differently to the disease depending on if they had a certain enzyme-producing molecule known as caspase 11.

Research showed that blocking this molecule in the infected mice resulted in lower inflammation, tissue injury and fewer blood clots in the animals’ lungs.

Humans have their own version of this molecule, or caspase 4, Amer said, and researchers discovered high levels of the enzyme in patients hospitalized for COVID-19 in intensive care units — a direct link to severe disease.

“It starts getting high because it has useful functions, but any molecule, when it gets too high, then these useful functions start becoming harmful,” Amer said.

The new work funded by the NIH will go beyond the study of the lungs and into how this molecule may impact the brain and the rest of the body, interfering with immune responses and possibly resulting in more blood clots in pathways leading to the brain and other vital organs – an entertained explanation for why Long COVID impacts people differently from case to case.

Currently, there are over 200 serious symptoms associated with Long COVID, according to the CDC.

Understanding how Long COVID comes to be is the first step in creating a treatment, Amer said. “Once you know the mechanism, then you can design what to target, where to target it and how to target it in order to reduce the damage being done.”

No one left behind

For Dr. Amer, finding that mechanism is an incredible research opportunity, but it’s also personal.

She herself contracted Long COVID during the pandemic. For three months, the leader in cutting edge research in her field suffered from terrible brain fog and other neurological symptoms after her second, thought seemingly mild, COVID-19 infection.

Amer has traveled all over the world, and confessed she’s gotten sick in many countries, including contracting the often deadly malaria. But nothing compared to Long COVID.

Amer would receive emails from her students, and read one sentence, but not remember what it said after reading it. She started having trouble typing on a keyboard. She couldn’t recall things people had just said to her moments before.

“I started thinking, ‘what’s gonna happen to my life?’ My job is a brain job. I lose my job, then what’s gonna happen to me?” Amer recalled. Now, she’ll head the brain-focused part of the project.

This continued for three months, before she gradually started to recover. Around six months, Amer said she began to feel normal again. Though she can’t be certain that she’s back to where she was before Long COVID, she acknowledges some people aren’t as lucky as she is.

“I have to find out, and I have to understand it, and I’m not going to let anybody be left behind,” she said.

This is now California’s worst summer COVID wave in years. Here’s why

This is now California’s worst summer COVID wave in years. Here’s why

California’s strongest summer COVID wave in years is still surging, and an unusual midsummer mutation may be partly to blame.

There are a number of possible culprits behind the worst summer infection spike since 2022, experts say. A series of punishing heat waves and smoke from devastating wildfires have kept many Californians indoors, where the disease can more easily spread. Most adults are also well removed from their last brush with the coronavirus, or their last vaccine dose — meaning they’re more vulnerable to infection.

But changes in the virus have also widened the scope of the surge.

Of particular concern is the rise of a hyperinfectious subvariant known as KP.3.1.1, which is so contagious that even people who have eluded infection throughout the pandemic are getting sick.

“COVID is extraordinarily common now,” said Dr. Elizabeth Hudson, regional chief of infectious diseases for Kaiser Permanente Southern California’s 16-hospital healthcare system.

COVID hospitalizations are ticking up, but remain lower than the peaks for the last two summers, probably thanks to some residual immunity and the widespread availability of anti-COVID drugs such as Paxlovid.

The World Health Organization has warned of COVID infections rising around the world, and expressed concern that more severe variants could emerge.

“In recent months, regardless of the season, many countries have experienced surges of COVID-19, including at the Olympics,” said Dr. Maria Van Kerkhove, the WHO’s technical lead on COVID.

Among those caught up was 27-year-old American sprinter Noah Lyles, who after winning the gold in the men’s 100-meter finals, came up short Thursday during the 200-meter finals, taking the bronze. Lyles collapsed after the race, fighting shortness of breath and chest pain, and was later taken away in a wheelchair.

“It definitely affected my performance,” he said of the illness, estimating that he felt “like 90% to 95%” of full strength.

The rate at which reported coronavirus tests are coming back positive has been rising for weeks — to above 10% globally and more than 20% in Europe. In California, the coronavirus positive test rate was 14.3% for the week that ended Aug. 5 — blowing past the peaks from last summer and winter — and up from 10% a month ago.

There were already indications in May that the typical U.S. midyear wave was off to an early start as a pair of new coronavirus subvariants — KP.2 and KP.1.1, collectively nicknamed FLiRT — started to make a splash, displacing the winter’s dominant strain, JN.1.

But by July, a descendant strain, KP.3.1.1, had clearly taken off.

“KP.3.1.1 is extremely transmissible and a little bit more immune evasive. It kind of came out of the blue during the summer,” said Dr. Peter Chin-Hong, an infectious-diseases specialist at UC San Francisco.

Cases are up at Kaiser Permanente Southern California, and “looking through the CDC data … KP.3.1.1 is really what is driving this particular surge,” Hudson said. “We are certainly much higher than we were last summer.”

Anecdotally, some infected people report being “pretty darn miserable, actually — really severe fatigue in the first two days,” Hudson said.

People may want to think their symptoms are just allergies, she said, but “it’s probably COVID. So we’re just really encouraging folks to continue to test.”

An initial negative test doesn’t necessarily mean you’re out of the woods, though. Officials recommend testing repeatedly over as many as five days after the onset of symptoms to be sure.

California has now reported four straight weeks with “very high” coronavirus levels in its wastewater, according to data released by the U.S. Centers for Disease Control and Prevention on Friday. That followed five weeks of “high” viral levels.

Last summer, California recorded only eight weeks with “high” coronavirus levels in wastewater, and never hit “very high” levels. In the summer of 2022, California spent 16 weeks with “high” or “very high” levels of coronavirus in wastewater.

“Fewer people got immunized this year compared to last year at this time,” Chin-Hong said. “That means, particularly amongst people who are older, they’re just not equipped to deal with this virus.”

There are 44 states with “high” or “very high” coronavirus levels in their wastewater, according to the CDC. Five states, and the District of Columbia, have “moderate” levels, and there were no data for North Dakota.

The CDC said coronavirus infections are “growing” or “likely growing” in 32 states, including California; are “stable or uncertain” in seven states, as well as the District of Columbia; are “likely declining” in Connecticut; and “declining” in Hawaii and Nevada. There were no estimates in eight states.

In Los Angeles County, coronavirus levels in wastewater jumped to 54% of last winter’s peak over the 10-day period ending July 27, the most recent available. A week earlier, coronavirus levels in wastewater were at 44% of last winter’s peak.

For the week ending Aug. 4, L.A. County reported an average of 479 coronavirus cases a day, double the number from five weeks earlier. Cases are an undercount, only reflecting tests done at medical facilities — not self-tests conducted at home.

In Santa Clara County, the most populous in the San Francisco Bay Area, coronavirus levels were high in all sewersheds, including San Jose and Palo Alto.

Hospitalizations and emergency room visits related to the coronavirus are also rising. Over the week ending Aug. 3, there were an average of 403 coronavirus-positive people in hospitals in L.A. County per day. That’s double the number from five weeks earlier, but still about 70% of last summer’s peak and one-third the height seen in summer 2022.

For the week ending Aug. 4, 4% of emergency room encounters in L.A. County were classified as related to the coronavirus — more than double the figure from seven weeks earlier. The peak from last summer was 5.1%.

“We’ve had a few people who have become very ill from COVID. Those are people who tend to be pretty severely immunocompromised,” Hudson said.

UC San Francisco has also seen a rise in the number of coronavirus-infected hospitalized patients. As of Friday, there were 28, up from fewer than 20 a week earlier, Chin-Hong said.

In the Bay Area, three counties have urged more people to consider masking in indoor public settings because of the COVID surge. Contra Costa County’s public health department “recommends masking in crowded indoor settings, particularly for those at high risk of serious illness if infected,” the agency said Tuesday, following similar pleas from San Francisco and Marin County health officials.

Compared with advice such as washing hands and staying away from sick people, suggesting wearing a mask can provoke strong opposition from some.

“The moment people see this, like in their mind, it sets off this chain reaction of, like, all the negative things of the pandemic, having to have society shut down and social isolation,” said Dr. Abraar Karan, an infectious-disease doctor and researcher at Stanford University.

But masks do help reduce the risk of infection, and people don’t have to wear them all the time to benefit. Karan says he socializes and eats at indoor restaurants. But he’ll decide to mask in other situations, like “when I’m traveling,” and, obviously, at work.

Doctors say that wearing a mask is one of many tools people can use to reduce their risk, and can be especially helpful when in crowded indoor settings.

Karan said he’s seen more coronavirus-positive patients while working shifts in urgent care, and he suggested that more healthcare providers take the time to order tests. He said he worries that when people come in with relatively mild symptoms, they may be sent home without testing.

But that could miss potential COVID diagnosis, which could allow a patient to get a prescription for an antiviral drug like Paxlovid.

Without testing, “you run the risk of taking shortcuts and not prescribing people meds that they actually should technically be getting,” Karan said.

7 Science-Backed Ways To Reduce InflammationCathrine Wessel

If you’ve scrolled through TikTok lately, you’ve probably seen tons of videos about how to reduce inflammation in your body. The topic is going viral for good reason, too—inflammation is the precursor of most modern chronic diseases, says Maya Feller, RD, the founder and lead dietitian at Maya Feller Nutrition, so it’s no wonder people are concerned with it.

Inflammation isn’t always a bad thing, so you don’t want to (and can’t) rid your body of it entirely. It’s actually a normal part of your body’s immune system.

“Inflammation is a completely natural process, and it’s a response usually to either injury or infection,” says Valerie Gustave, MD, a gastroenterologist at Lenox Hill Hospital and NYU Langone Medical Center. For example, acute inflammation might occur when you get a cut or twist your ankle to help your body heal.

But when inflammation is chronic, it can be an issue. Rheumatoid arthritislupusCrohn’s disease and irritable bowel syndrome are all inflammatory conditions, and symptoms like fatigue, low energy, recurrent rashes, joint pain, and unexplained stomachaches can also be caused by persistent inflammation, says Micaela Bayard, MD, a rheumatologist at Mount Sinai. For any of these conditions or symptoms, you should speak with a doctor to evaluate your inflammatory markers, confirm an issue, and help you determine the best path forward.

In addition to medicine, part of that path might include lifestyle changes. These expert-approved tips are the foundation of healthy living—and can possibly help prevent excess inflammation in the future.

How To Reduce Inflammation

If you’re dealing with fatigue, recurrent rashes, joint pain, or any of the symptoms described above, it may help to make an appointment with your doctor to rule out any chronic conditions. And if you want to take better care of yourself in general and reduce your risk of inflammation, you can start with the basics, Dr. Gustave says. Here are seven simple, science-backed ways to reduce inflammation and boost your health overall.

Drink Less Alcohol

Cutting back on booze is one way to tamp down inflammation.

“The body recognizes alcohol as a toxin,” says Feller, so it’s no surprise that it gets a big reaction from your immune system. “The problem with alcohol is that it can very actively stimulate what we call ‘pro-inflammatory molecules’ that trigger more inflammation,” says Dr. Bayard.

And if you already have a chronic condition that causes your body to be at an “elevated level of inflammation,” drinking alcohol can make things worse, she says.

Drinking alcohol contributes to systemic inflammation (the kind that causes chronic diseases) by messing with your gut’s microbiome, liver function, and even brain. And all those symptoms you get during a hangover? They’re an inflammatory response, too—and their severity might reflect systemic inflammation caused by drinking, according to a 2024 study in Alcohol: Clinical and Experimental Research. The more intense your hangovers are, the more inflammation you’re probably experiencing—and this drinking-inflammation cycle may put you at significantly greater risk of long-term health problems like significant liver damage and tissue damage in your gut, the study found.

If you’re looking to make a change, you don’t have to go cold turkey.

“Reduce in a way that is realistic for you,” Feller says. The less alcohol, the better, but “moderate drinking” for a woman is described as one drink or less per day, per the Centers for Disease Control and Prevention (CDC).

Cut Out Tobacco

Consuming tobacco in any form (cigarettesvapes, and hookah) harms your gut and lungs, and when it comes to inflammation, smoking can put you at risk for developing chronic health issues. In fact, one of the most well-documented causes of rheumatoid arthritis is smoking. This is because inflammation—your body’s natural immune response—can be found wherever there’s cell or tissue damage, and smoking causes plenty of damage in your body, says Dr. Bayard. “If you’re inhaling something that can be damaging to the tissue, that’s an area where inflammation can then accumulate,” she says.

The bottom line? Stopping smoking will make a big difference on your overall health, and not just your inflammatory markers, says Dr. Gustave.

Get A Good Night’s Sleep

Getting enough quality sleep is easier said than done, but turns out it’s super important for your health and for mitigating inflammation in the body. This is because sleep is a vital part of our immune response. Sleep is restorative, and during sleep, your immune system releases messenger proteins that help healing and fight infections, Dr. Bayard says.

Inconsistent sleep may be associated with higher levels of inflammation, especially for women, according to a 2020 study in Frontiers in Neurology. Sleep disturbances like waking up in the middle of the night could trigger inflammatory responses in the body, the study found. Without deep, uninterrupted sleep, your body won’t have the time it needs to let your immune system regenerate and heal the acute inflammation in your body, says Dr. Bayard.

As for how much sleep you should get? You’ll need less as you get older, but six to seven hours is a good place to start, says Dr. Bayard.

Reduce Stress

Stress plays a role in inflammation, says Dr. Bayard. One major reason is that cortisol (a stress hormone) can cause your body to switch on genes that trigger an inflammatory response. Stress can prompt inflammation in the body and may even lead to conditions like depression, per a 2022 study in the journal BiomedicinesFinally, stress can disrupt your sleepappetite, and mindfulness, which all play a role in inflammation, Dr. Bayard says.

Get Some Physical Activity In

Exercise can decrease inflammation by releasing proteins that lower an inflammatory response and helping metabolize excess sugars in the bloodstream, says Feller.

While it doesn’t quite matter what you do—just as long as you’re active for about 30 minutes most days—if you’re concerned with inflammation, high-impact exercise might not be the way to go. That’s because exercise that is too hard on your body could cause more inflammation, says Dr. Bayard. (Everyone is different, so pick whatever gets you moving and see how it feels for you.)

If you’re not sure where to start, low-impact exercise might be just what you need to manage inflammation (without going overboard or stressing your body out). Bikingwalking with supportive shoesswimming, or hopping on the elliptical are all examples of low-impact workouts that can help you get all of exercise’s anti-inflammatory benefits.

Be Mindful Of Additives And Processed Foods

Sugar, salt, and processed foods might be hard to avoid, but they can play a role in inflammation. High levels of sugar can promote tissue damage and breakdown, leading to more inflammation, says Dr. Bayard, and eating processed foods pose a challenge to our digestion, which can promote inflammation in the gut.

“We’re learning a lot about how these chemicals that we take in impact our body,” says Dr. Bayard, but striving to eat less of them could help.

Eat The Rainbow

Finally, diet plays a role in inflammation, and WH has you covered with an anti-inflammatory food guide (think: plenty of nutritious whole foods packed with omega-3s and plant-based options). In addition to following that diet, a Mediterranean diet promotes eating limited red meat, green vegetables, and non-processed foods, all of which can be anti-inflammatory, says Dr. Bayard.

Overall, the key to reducing inflammation in your body is prioritizing variety and non-processed foods.

“If people can eat 30 different diverse plant foods over the course of the week, that’s very beneficial for gut health,” says Feller. “And we know that the gut has a big role in terms of immune health and also inflammatory conditions throughout the body.”

Spain, France, Germany: Heatwaves sweep across Europe with devastating consequences

Spain, France, Germany: Heatwaves sweep across Europe with devastating consequences

Spain, France, Germany: Heatwaves sweep across Europe with devastating consequences

There’s no end in sight for Europe’s searingly hot summer, as heatwave warnings have been issued from Spain to Germany.

In Paris, too, Olympians have been forced to compete in searing heat – extremes that would have been “virtually impossible” without human-caused climate change, according to climatologist group World Weather Attribution (WWA).

Droughts and wildfires have broken out across the Mediterranean as a result of the hot weather, which looks set to continue throughout August and beyond in some parts.

Extreme heat currently claims more than 175,000 lives annually in Europe, with numbers set to soar, according to a report released by the World Health Organization (WHO) today.

Spain: Temperatures could surpass 43C

Yellow, orange and extreme red heatwave warnings have been issued by Spain’s Meteorological Agency (AEMET) as temperatures threaten to reach 43C in the southeast.

Sweltering highs are forecast across the country’s east coast, south and centre for the majority of August, reaching peak intensity on Thursday – with one in nine of AEMET’s weather stations reaching 40C or higher.

Baza in Grenada and northwest Murcia will be the hardest hit.

The temperature in Barcelona broke records on Tuesday, racing 40C – the hottest day the Catalan capital has seen in at least 110 years, when records began.

According to AEMET, temperatures are likely to be higher than normal until October across much of Spain.

Italy: Rome under maximum heat warning

Helicopters and fire engines tackled a large fire in north-west Rome on Wednesday as a heatwave gripped the Italian capital.

The city has been placed under a maximum heat warning, with temperatures in the high 30s expected on Thursday and Friday.

Florence, Bologna, Milan and Turin are among the other cities also under a red weather warning.

While the blaze on Monte Mario is now under control, Rome and the surrounding areas remain on high alert for wildfires.

The south of the country is facing persistent drought, with farmers in Sicily forced to slaughter or sell off livestock due to severe water shortages.

Germany: Heat warning issued as temperatures creep over 35C

It’s not only southern Europe facing the heat: German Weather Service DWD has issued a warning as parts of the country face 35C-plus temperatures.

Wednesday was expected to be the hottest day of the year – particularly southwest Germany, which will today be hit with thunderstorms and heavy rain as the warm air moves north.

Campaign groups have warned that the country is ill prepared for heatwaves, with Frankfurt’s Senckenberg Society for Nature Research urging the development of early warning systems as the threat of wildfires ramps up.

Environmental non-profit Deutsche Umwelthilfe, meanwhile, released a ‘heat check’ revealing that less than half of the 190 German cities analysed are adequately protecting their citizens against hot weather.

They say more unsealed surfaces and green spaces are needed in cities like Frankfurt and Stuttgart to make them liveable.

France: Extreme heat hits Paris Olympics

Temperatures in Paris reached 35C this week as the city continues to host the Olympic Games.

WWA has warned the high temperatures could impact athletes’ performance and lead to an increase in heat related illness.

Southeastern France is also facing extreme weather, with temperatures of up to 40C expected until at least 4 August. Orange heatwave warnings have been issued by weather service Météo-France in Corsica, Provence-Alpes-Cote d’Azur, Auvergne-Rhone-Alpes and the Occitanie region.

“Extreme heat events like July 2024 in the Mediterranean are no longer rare events,” says WWA. “Similar heatwaves affecting Greece, Italy, Spain, Portugal and Morocco are now expected to occur on average about once every 10 years in today’s climate.”

Mediterranean heatwave ‘virtually impossible’ without climate change: scientists

The punishing heat experienced around the Mediterranean in July would have been “virtually impossible” in a world without global warming, a group of climate scientists said Wednesday.

A deadly heatwave brought temperatures well above 40 degrees Celsius (104 Fahrenheit) to southern Europe and North Africa, where such extreme summer spells are becoming more frequent.

Scorching heat claimed more than 20 lives in a single day in Morocco, fanned wildfires in Greece and the Balkans, and strained athletes competing across France in the Summer Olympic Games.

World Weather Attribution, a network of scientists who have pioneered peer-reviewed methods for assessing the possible role of climate change in specific extreme events, said this case was clear.

“The extreme temperatures reached in July would have been virtually impossible if humans had not warmed the planet by burning fossil fuels,” according to the WWA report by five researchers.

The analysis looked at the average July temperature and focused on a region that included Morocco, Portugal, Spain, France, Italy and Greece.

Scientists used this and other climate data to assess how the heat in July compared to similar periods in a world before humanity began rapidly burning oil, coal and gas.

They concluded the heat recorded in Europe was up to 3.3C hotter because of climate change.

Beyond the Mediterranean, intense heat reached Paris this week where athletes competing in the Olympic Games withered as temperatures hit the mid-30s this week.

“Extremely hot July months are no longer rare events,” said Friederike Otto, a climate scientist at Imperial College London, a co-author of the study.

“In today’s climate… Julys with extreme heat can be expected about once a decade,” she said.

Scientists have long established that climate change is driving extreme weather and making heatwaves longer, hotter and more frequent.

This latest episode came in a month when global temperatures soared to their highest levels on record, with the four hottest days ever observed by scientists etched into the history books in July.

The past 13 months have been the warmest such period on record, exceeding a 1.5C limit that scientists say must be kept intact over the long term to avoid catastrophic climate change.

Scientists make ‘incredibly worrying’ discovery after observing pattern in one of Earth’s largest ice fields: ‘We risk irreversible, complete removal of them’

Scientists make ‘incredibly worrying’ discovery after observing pattern in one of Earth’s largest ice fields: ‘We risk irreversible, complete removal of them’

Leslie Sattler – July 28, 2024

Alaska’s Juneau Icefield is melting at an alarming rate, doubling its pace of decline in recent decades.

This vast expanse of interconnected glaciers is shrinking faster than ever before, according to The New York Times, raising what it said scientists called “incredibly worrying” concerns about the future of our planet’s ice.

What’s happening?

The Juneau Icefield lost 1.4 cubic miles of ice annually between 2010 and 2020, according to a recent study published in the journal Nature Communications. That’s twice the rate of melting observed before 2010.

Since the late 18th century, this massive ice field has shed a quarter of its volume, with the most dramatic losses occurring in recent years.

Bethan Davies, who led the research, gave a stark statement to the New York Times: “If we reduce carbon, then we have more hope of retaining these wonderful ice masses. The more carbon we put in, the more we risk irreversible, complete removal of them.”

Why is the melting Juneau Icefield concerning?

The rapid melting of this Alaskan ice field is a clear sign that our planet is overheating.

As the ice disappears, it affects more than just the local landscape. Here’s why this matters to all of us:

Sea level rise: Melting glaciers contribute to rising sea levels, threatening coastal communities worldwide.

Climate feedback loop: As ice melts, it exposes darker land beneath, which absorbs more heat and accelerates warming.

Fresh water supply: Glaciers act as natural reservoirs, providing fresh water for ecosystems and human communities.

Wildlife impact: Many species depend on these icy habitats for survival.

The changes in the Juneau Icefield serve as a stark reminder of the urgent need to address our planet’s overheating. By taking action now, we can help protect these vital ecosystems and the communities that depend on them.

What’s being done about the Juneau Icefield?

While the situation is serious, there’s still hope. Scientists, policymakers, and laypeople are working together to slow the melt.

For example, studies like this one help us understand the problem and develop targeted solutions. International efforts, such as the Paris Agreement, aim to limit planetary heating and protect vulnerable areas. And many communities are switching to renewable energy sources to reduce carbon pollution.

You can make a difference, too, with actions big and small. The most important thing you can do is get educated about topics like this and use your voice to help steer public sentiment and beyond, however you feel.

By making these small changes in our daily lives, we can contribute to a cooler future for our planet. Remember, every action counts when it comes to preserving our planet’s incredible ice fields and the vital role they play in our global ecosystem.
