Tick-borne Wetland virus, newly discovered in China, could cause damage to brain, researchers say
Scientists are warning of a new tick-borne disease called Wetland virus (WELV) that was recently discovered in China.
A member of the Orthonairovirus genus of viruses, WELV previously infected a man in Inner Mongolia, China, in 2019, but it was not identified until this new study, which was published in The New England Journal of Medicine last week.
The 61-year-old man, who was bitten by a tick at a wetland park, sought medical attention for “persistent fever and multiple organ dysfunction,” according to the study.

A team of researchers from the Beijing Institute of Microbiology and Epidemiology isolated the virus from that patient and later identified it as WELV.

Using laboratory testing, the team went on to detect the virus in 17 other patients in China whose symptoms included fever, headache, dizziness, muscle pain, fatigue, back pain, arthritis, swollen lymph nodes and neurologic issues, the study findings noted.
Some also had petechiae, which are spots on the skin caused by bleeding from capillaries.
Eight of the patients who had recovered were found to have four times as many WELV-specific antibodies than those who had not yet recovered, the researchers found.

After receiving antiviral medications, antibiotics or immunoglobulin therapy, all the patients recovered without any long-term health effects.
The Wetland virus is similar to the Crimean–Congo hemorrhagic fever, a virus that causes fever, headache, muscle pains, vomiting, diarrhea, bleeding into the skin and liver failure in severe cases, according to the study findings.
The virus could cause brain damage and death, researchers found.
The RNA of the virus was found in five different tick species, along with sheep, horses, pigs and rodents in northeastern China.
When injected into mice and hamsters, the virus was shown to cause brain damage and death.

Diagnosing the Wetland virus could prove to be a challenge because its symptoms usually match that of a “non-specific illness,” the researchers noted.
“Improving surveillance and detection for emerging orthonairoviruses will allow a better understanding of the effect that these viruses have on human health,” they wrote.
Doctors react to viral discovery
Dr. Marc Siegel, senior medical analyst for Fox News and clinical professor of medicine at NYU Langone Medical Center, said the findings spotlight the wide range of viruses that a tick or other “insect vector” can transmit.
“This can cause hemorrhagic fever and can be quite deadly,” Siegel, who was not involved in the study, told Fox News Digital. “It’s worth keeping an eye on but is very rare.”
WHAT IS EEE, THE MOSQUITO-BORNE DISEASE THAT KILLED A NEW HAMPSHIRE MAN?
Dr. Edward Liu, chief of infectious diseases at Hackensack Meridian Jersey Shore University Medical Center, noted that tick-borne diseases typically don’t spread quickly.
“They slowly expand their territory as ticks shift their environments but are nothing like respiratory viruses, which transmit much more easily and literally can spread from continent to continent in one day,” he told Fox News Digital.
It’s important to identify and avoid areas where ticks may live, including wooded, grassy or brushy areas, according to the CDC. (iStock)
Viruses or bacteria that live in ticks are specific to certain species, Liu noted, “so those viruses don’t automatically transfer to ticks in the U.S.”
“I am not worried about a COVID-19-type pandemic,” he added.
‘SLOTH FEVER,’ OR THE OROPOUCHE VIRUS, HAS ENTERED THE US, HERE’S WHAT TO KNOW
He did, however, echo Siegel’s warning of potentially fatal ramifications, as the Wetland disease causes hemorrhagic fever, which can be deadly.
“Elderly people and immunocompromised patients are at the greatest risk,” Liu said.
Preventing tick bites
The best means of prevention against tick-borne diseases is to protect against bites, experts say.
It’s important to identify and avoid areas where ticks may live, including wooded, grassy or brushy areas, according to the U.S. Centers for Disease Control and Prevention (CDC). They can also live on animals.

The CDC recommends treating all clothing and gear with products containing 0.5% permethrin, which helps to repel ticks.
People can also apply an EPA-registered insect repellent, such as those containing DEET.

After coming inside after spending time outdoors, the CDC recommends checking all clothing, gear and pets for ticks. It is best to shower within a couple of hours.
The agency also suggests doing a full body check.

Clothing can be dried at high heat for 10 minutes — or washed with hot water — to kill any ticks.
Anyone who experiences symptoms of illness after a tick bite should contact a medical provider.

Summer fun in the sun is being taken to a new extreme.
“Tanmaxxing” is a social media trend that involves maximizing sun exposure and tanning the skin more intensely.
Popular among Gen Z, the practice combines time spent in direct sunlight with a variety of tanning products like oils, bronzers and gels.

Creators on social media are showing off their dramatic tan lines and outdoor set-ups — some even forgoing sun protection or adding tanning bed sessions.

While spending time outdoors can help boost mood, support the body’s production of vitamin D and reduce screen time, dermatologists warn that excessive sun exposure — especially as promoted by the tanmaxxing trend — can be dangerous.
New York-based board-certified dermatologist Dr. Michael Tassavor, MD, emphasized that there is “no such thing as a safe, natural tan.”

“Tanning is damage,” he said in an interview with Fox News Digital. “Tanfluencers sell a deep tan as a ‘wellness upgrade,’ but a tan isn’t a glow-up — it’s your skin’s visible distress signal that DNA damage has already happened.”
“As a skin cancer specialist, I’ve taken care of thousands of skin cancers on patients who ‘tanmaxxed’ before it had a name. Most regret it.”
Using a tanning bed before 35 years old can raise melanoma risk by about 75%, an expert warned. (iStock)
The World Health Organization classifies UV radiation and tanning beds as Group 1 carcinogens, which is the same category as tobacco and asbestos.
Using a tanning bed before age 35 can raise melanoma risk by about 75%, Tassavor noted.

“The damage compounds silently and shows up years later, once the easy window to intervene has closed,” he said.
According to Tassavor, two common beliefs behind tanmaxxing are false: Skipping sunscreen does not produce a “better” tan, and a base tan does not protect the skin from future sunburns.
“Most of your vitamin D can come from diet and supplements, and your skin is efficient enough to top up what it needs from ordinary incidental exposure,” a dermatologist said. (iStock)
Sunlight “isn’t the enemy,” the dermatologist noted, but there’s no need to chase it.
“Most of your vitamin D can come from diet and supplements, and your skin is efficient enough to [get] what it needs from ordinary incidental exposure,” he said.

“Vitamin D matters for bone density, and sun does give some people a genuine mood lift, but there’s no evidence that anyone has to go out of their way to sunbathe for it, and no evidence that diligent sunscreen use harms bone health.”

To safely expose yourself to the sun, Tassavor recommends using SPF 30 sunscreen and reapplying every two hours. Tanning beds should be avoided “entirely,” he cautioned, because there is “no safe dose” of UV exposure and using them accelerates skin aging.

The Great American State Fair was postponed Saturday after multiple people reportedly fainted the day before, forcing thousands of visitors to pivot during celebrations for America’s 250th anniversary.
Friday’s medical emergencies required onsite attention as crowds flocked to the nation’s capital for Independence Day.
The fair reopened later Friday evening but was postponed again Saturday.
HEART ATTACKS AND STROKES RISING WITH EXTREME WEATHER EVENTS, RESEARCH SUGGESTS
Fox News Digital asked attendees what it took to get to the capital and what they made of the closure.
“We are so blessed to live in the best country in the world,” Whitney Thomas, a mother from North Carolina who traveled with her family for the Great American State Fair, told Fox News Digital Friday.

Despite the weather closure, she said her family was able to enjoy the State Fair Thursday evening and planned to wait out the heat in nearby museums until the fair reopened.
“I wanted my kids, who are 9 and 10, to be able to experience this with us,” she said.
“You cannot tell me that America was won by shutting things down when it gets hot.”
Brad Shultis, a retired Marine who traveled from Stafford, Virginia, expressed frustration over the decision to halt festivities.
“You cannot tell me that America was won by shutting things down when it gets hot,” he told Fox News Digital.
FAMOUS LANDMARKS SLASH VISITING HOURS AS DEADLY HEAT WAVE THREATENS TOURISTS
“It gets hot, and we shut it down because it’s hot? Who cares? If it’s too hot, stay home.”
Shultis noted that he drove to Springfield and took the Metro just to be turned away right after buying lunch. He questioned the decision to shut down the celebration of America’s 250th anniversary, arguing that if people find the weather too hot, they should simply stay home or seek medical help rather than forcing a mass evacuation for those who spent time and money to get there.

Wendy Lamb, who traveled eight hours from Connecticut with her family to support the state’s booth, noted that organizers were likely worried about the intense conditions and simply did not want visitors to suffer.

While disappointed that her home state did not send official representation due to budget issues, Lamb and her fellow travelers refused to let the heat ruin their first trip to Washington, D.C.
“We’ve had a really, really fun time so far,” added John, another member of the group.

He said they plan to navigate the heat by moving from museum to museum and using the Metro system to stay cool until the gates reopen.
For these visitors, the setback was minor compared to the emotional weight of seeing the U.S. Capitol and the Rotunda.

“I mean, we are so fortunate we are free, and yet we have people out there that hate our country. … it’s very emotional,” said Pat Lamb, who fanned her face to stop tears welling in her eyes as she described the pride she felt for the nation.
The decision to close the fairgrounds aligns with severe weather protocols designed to prevent mass casualty medical events.

To prevent severe complications like permanent organ damage or death, the CDC advises that anyone exhibiting warning signs such as confusion, slurred speech or a loss of consciousness should receive immediate medical treatment.
Public health officials urge individuals in high-heat environments to seek shade, stay heavily hydrated and identify air-conditioned cooling centers.

Many of the American colonists’ eating habits have made a comeback in recent years. They ate minimally processed, locally sourced whole foods and regularly incorporated organ meats into their meals.
Livestock and many Old World crops had already been introduced to North America by European explorers and settlers during the centuries before the nation’s founding.
Early settlers adapted European cooking traditions using ingredients available in North America, the Center for the Study of the Presidency and Congress (CSPC) reported.
Indigenous peoples introduced corn to the colonists, and it became a core ingredient in many of their recipes. Beans, squash, and potatoes were among the other crops that became incorporated into colonial cooking, according to the CSPC.
“Cornmeal appeared in dishes such as hasty pudding — a thick porridge similar to polenta — and johnnycakes, simple griddle cakes that were popular from New England to the South,” History Facts reported.
Cornmeal Johnnycakes, roast pork and cream cheese are distinctly early-American foods the CSPC has recipes for on its website.

Regional customs and crops greatly influenced what the colonists ate. Rice and okra grew well and were plentiful in the South, where French and African influences also shaped eating habits.
Dutch, English and German immigrants largely settled in the north and established the region’s culinary traditions.
Seafood such as rockfish and crab dominated the diets of early Maryland settlers, NPR reported.
Meat was a status symbol, local food historian Joyce White told the publication. Beef was prized, and chicken was often saved for egg production.
“If it’s your pig or cow coming from your plantation, you don’t want to waste it,” White said.

Thomas Jefferson was known for his decadent tastes and a fondness for French wine and macaroni and cheese. Records show that black-eyed peas, turnip greens and ham were also part of the Founding Father’s diet.
Salted and preserved fish and meats, including bacon, sausage, liver pudding and offal, were staples of working-class people’s diets, while the upper classes indulged in such luxuries as white flour and sugar.
Interest in these traditional foods has resurfaced in recent years as some Americans seek diets centered on whole, minimally processed ingredients.

Advocates of the Make America Healthy Again movement, for instance, have promoted organ meats, or offal, as some of the cheapest and most nutrient-dense foods people can eat.
Stews that evolved as ingredients became available were also common an America’s early days.
The amount of alcohol the colonists consumed was “staggering,” Adrian Miller, author of “The President’s Kitchen Cabinet,” told NPR.
“They were very open about how much they were drinking,” he said.

George Washington wrote a recipe for “small beer” in a journal he kept as a young colonel in charge of the Virginia militia during the Seven Years’ War, Fox News Digital previously reported. The New York Public Library houses the journal.
“Small beer,” according to the library, derives its name from the small amount of alcohol it contains. It was quick to make, safer to drink because the brewing process helped eliminate bacteria in the water — and it was an “everyday, mainstay beverage,” the library reported.
“While the 1776 Diet has some positives — such as emphasizing whole foods, home cooking and fewer ultra-processed foods — it’s not one I’d recommend following too literally,” registered dietician Lisa R. Young, adjunct professor of nutrition at New York University, told Fox News Digital.

“Colonial Americans often ate foods like salted ham, organ meats and other preserved meats out of necessity,” she said. “Today, we know it’s best to limit processed and cured meats because they’re high in sodium and saturated fat, and organ meats, while nutrient-dense, are best eaten in moderation due to their high cholesterol content.”
Focus on the healthiest aspects of the 1776 diet, Young recommended. That includes plenty of fruits and vegetables, beans, whole grains, fish and lean proteins.
“Of course, you can emulate the Founding Fathers’ diet for the week of the 250th anniversary,” she said. “What you eat for a day or a week won’t matter much in the scheme of things.”

Some of the Founding Fathers drank a lot of ale, often in the morning, Young noted.
“We shouldn’t emulate that,” she said.
