Doctors have issued a warning about an alarming sign on your hands that could be a symptom of a silent killer. Endocarditis, a rare and potentially fatal infection of the inner lining of the heart, is usually caused by bacteria entering the blood and travelling to the heart, the British Heart Foundation says. While symptoms can range from night sweats to swelling in your feet, another sign could be on your palms. If you spot any red or purple marks on your palms or fingers, you may need to seek the advice of a GP. Endocarditis is very rare in people with normal hearts who have no other risk factors but the symptoms have sometimes been known to start suddenly and are severe – in some cases it can even be fatal. Although the heart is usually well protected against infection, it may be easier for bacteria to bypass the immune system in people who have: an artificial heart valve congenital heart disease hypertrophic cardiomyopathy – where the heart muscle cells have enlarged and the walls of the heart chambers thicken damaged heart valves had endocarditis before. Other symptoms of endocarditis The initial symptoms of endocarditis are similar to flu and include a high temperature, chills, headache, joint and muscle pain. Without treatment, the infection damages the heart valves and disrupts the normal flow of blood through the heart. Endocarditis is treated with a course of antibiotics given via a drip and you’ll need to be admitted to hospital for this. It’s also possible to have surgery to repair or replace a damaged valve or to drain any abscesses. The NHS warns that endocarditis is a serious illness, especially if complications develop. Early diagnosis and treatment is vital to improve the outlook for the condition. Marks and Spencer launches summer sale and there’s huge savings on kids’ clothing

TAMPA, Fla. (WFLA) — Five people are confirmed dead in the Tampa Bay area due to a rare, flesh-eating bacteria in the waters. According to Florida Health, Vibrio vulnificus is a bacterium that naturally occurs in warm, brackish seawater and requires salt. Ivermectin still not effective or approved for COVID-19 treatment, FDA says There have been 25 reported cases and five deaths since January 2023. “Living in Florida, being around the marine environment, we need to be aware of what it is,” said Dr. Eric Shamas, an emergency medicine physician at Bayfront Health St. Petersburg. There are two confirmed deaths in Hillsborough County, one in Sarasota County, one in Polk County, and one in Pasco County. In 2022, there were 74 total cases and 17 deaths. Most occurred in Lee County after Hurricane Ian’s waters flooded the community. According to Florida Health, a person can get infected with Vibrio vulnificus when eating raw shellfish, particularly oysters, and entering seawater with an open wound, especially in the summer months Opioids, obesity now ranked as top public health threats in new poll “Whenever you have a break in the skin and you’re in a marine environment then theoretically you’re at risk,” Shamas said. “It’s very important to keep in mind these severe infections are very rare.” Health officials warn citizens to not enter the water if they have fresh cuts or scrapes, as the bacteria can enter the bloodstream rather quickly. Bloodstream infections are fatal 50 percent of the time. “If you have wounds, maybe stay out of the water,” Shamas said. “If you suffer a cut while in the water, just wash it out very thoroughly with soap and water. Monitor your symptoms and follow up with your doctor if you have any questions.” Common symptoms of the flesh-eating bacteria include vomiting, diarrhea, abdominal pain, and infection of the skin (if there is an open wound). Those with healthy immune systems are likely to experience a mild infection.

To prevent Vibrio vulnificus infections, avoid eating raw shellfish and oysters, cook shellfish thoroughly, avoid cross-contamination of cooked seafood and raw seafood, avoid exposure of open wounds or broken skin to warm salt or brackish water, and wear protective clothing when handling raw shellfish. Seek medical help right away if you believe you may have an infection. For more information on care and treatment specifics, visit the CDC’s website.

It may feel like pandemic déjà vu: New Covid-19 variants are afoot, and hospitalizations are again on the rise. Eris recently became the most prevalent Covid variant, but now international health officials have their eyes on a new variant of concern. The latest strain — called BA.2.86 — has so far been detected only in the US, Denmark and Israel. It’s caught the attention of the US Centers for Disease Control and Prevention and the World Health Organization, which are closely monitoring the situation. For now, experts aren’t too concerned. 1. What is BA.2.86? The strain was first spotted by virus trackers in mid-August. Not much is known yet about how it stacks up against other variants. It appears to be a descendant of the BA.2 variant that first emerged in early 2022, but this lineage has more than 30 mutations on its spike protein, which helps the virus latch onto cells and cause infection. That could make it better at evading immunity from vaccines and past infections. 2. What about Eris? Eris, formally called EG.5, is a descendant of a group of coronavirus strains labeled XBB. These are all offshoots of the omicron variant, which arose in late 2021. EG.5 made up an estimated 17.4% of global cases in the week ending July 23, according to the WHO, up from only 7.6% four weeks earlier. It recently became the most common strain in the US, according to estimates by the CDC. 3. How concerning are the new variants? Eris poses a low risk to global public health, the WHO said. Although it’s growing in prevalence in comparison with other strains and appears to be better at evading the body’s immune defenses, there’s no evidence it causes more severe disease or can spread more easily than other versions of Covid. Pfizer Inc. and Moderna Inc. have both said that their updated Covid vaccines, formulated to target the variant known as XBB.1.5, protected against Eris in early studies. As for BA.2.86, its mutations give it “all the hallmark features of something that could take off,” said Kristian Andersen, a Scripps Research immunologist and microbiologist. However, it’s too early to tell. 4. What symptoms does it cause? Share this articleShare The symptoms of Eris and other variants seem to be the same as those caused by previous strains, according to Thomas Russo, chief of the Division of Infectious Diseases at the University of Buffalo’s medical school. Common ones include a runny nose, headache, fatigue, a sore throat and sneezing. People who are older, have compromised immune systems or suffer from multiple other conditions are at higher risk for more severe effects. These may include lower respiratory disease, chest pain and shortness of breath. The virus still kills hundreds of people each week in the US, so it’s important to get tested if you think you may be infected. 5. What’s causing a rise in US hospitalizations? The number of people admitted to the hospital with Covid-19 is on the rise for the first time this year in the US, and wastewater data has also shown cases ticking up. Hospitalizations are up in multiple other countries as well. But there’s no evidence linking increased hospitalizations to new strains, the WHO says. Experts point to other likely culprits: Extreme heat is driving gatherings indoors, where the coronavirus spreads more easily. Also, with the pandemic over, people are traveling again and no longer wearing masks. And for many people, it’s been months since they last got a vaccine or contracted the virus, meaning their immunity against infection is waning. 6. Is the US prepared for a rise in Covid-19? The US has scaled back its response to Covid-19. The government no longer purchases vaccines and treatments for the public, and free tests aren’t as widely available. Still, experts say the US isn’t likely to see the kind of surge in cases that upended life in the early years of the pandemic. Because of vaccination and prior infections, the population has widespread protection from severe disease, and therapies like Pfizer’s Paxlovid antiviral drug can reduce the risk of hospitalization and death if they’re taken early on. Even after recent increases, hospital admissions are lower than at at any other point since at least August 2020, according to CDC data. 7. What can you do to protect yourself? New booster vaccines will be available later this year, and experts say they’re especially important for vulnerable people. If you’re at higher risk and you’re going to be in a situation where exposure is likely, such as a large gathering, Russo says you can consider getting a booster shot of one of the older vaccines that are already on the market. In any case, masks help protect against infection. Pharmacies still offer Covid-19 testing services and sell at-home tests. If you’re at high risk and you develop symptoms, a test can help determine whether you should start taking Paxlovid. More stories like this are available on bloomberg.com ©2023 Bloomberg L.P.

Infections with Vibrio vulnificus are rare, especially in the Northeast. But a few recent cases suggest that precautions are wise for some wading into the water. The News With Labor Day and the start of a new school year looming, throngs of New Yorkers will head to the beach this weekend, braving traffic, sunburns, maybe sharks — and Vibrio vulnificus, a nasty, flesh-eating bacteria that thrives in warm seas and brackish water. Since the beginning of July, four people in the greater New York area have been infected with the bacteria, including three who have died, according to health officials in New York and Connecticut. Two of the people sickened in Connecticut had been exposed to saltwater or brackish water in the Long Island Sound. One had eaten raw oysters, which can become infected with the bacteria during warm spells. (The cause of the fourth infection, which killed a Suffolk County resident, is not known.) “If we were having this conversation 15 years ago, we’d be talking about infections along the Gulf Coast,” said Dr. William Schaffner, an infectious disease specialist at Vanderbilt University School of Medicine. “But now these infections are creeping up the East Coast.” The bacteria Vibrio vulnificus is related to the type that causes cholera.Janice Haney Carr/Centers for Disease Control and Prevention The Back Story: An infection that surprises beachgoers. It’s not clear whether the appearance of these cases farther north than usual may be a result of better diagnosis or to warming waters associated with climate change. The illness, technically called vibriosis, may be caused by infection with several related bacteria. Among the worst is V. vulnificus, which is relatively rare but can be deadly for those who are vulnerable, with survival rates as low as 33 percent, according to one scientific paper. The bacterium spreads most commonly in two ways. When people swim in waters contaminated with V. vulnificus, an open sore or cut can provide an entry point for the organism. From there it spreads, becoming a so-called flesh-eating infection that extends quickly beyond the wound into healthy tissue. Then it may spill over into the bloodstream, causing a life-threatening condition called sepsis. The bacterium also spreads when people who are immunocompromised or have liver disease eat raw oysters that are contaminated. Physicians warn patients with these conditions against eating raw oysters, which become infected by seawater they filter for food. Older people are generally at greater risk. The three patients who fell ill in Connecticut were all over age 60. People who take medications to reduce stomach acid may also be more likely to get infected or to develop complications following infection. If you’re among the vulnerable, wear shoes that protect against cuts and scrapes when you’re in salty or brackish water. Wear protective gloves when handling raw seafood. Avoid swimming in the ocean if you have a cut, scrape or other abrasion that might let in the bacterium. What to Watch: The bacterium seizes on openings. Vibriosis causes a wide range of symptoms, including diarrhea and stomach cramps, vomiting, fever, chills, ear infections and wound infections. The intestinal problems occur more quickly in people who have ingested the bacterium, usually by eating raw oysters. Ear and wound infections will become red, swollen and extremely painful over a bit more time. Blisters filled with clear liquid may appear on the skin. Symptoms usually appear within 12 to 24 hours of exposure, and people should seek medical care as soon as possible. Tell doctors about the exposure: The infection can spread quickly if left untreated. “If the wound starts to look red, puffy and painful, or has a discharge, or redness spreading beyond the edges of the wound, you need to get medical attention right away,” Dr. Schaffner said. “Don’t try to tough it out and wait to see if it gets worse tomorrow.” A lab test is needed to make the diagnosis. Treatment involves antibiotics and supportive care, but surgery may be required to clean out an infected wound and stop the spread of the infection. Your Beach Weekend: The vulnerable should exercise caution. Consider avoiding the water, and not even walking on the beach or wading, if you have an open wound, including one from a recent surgical operation or piercing or tattoo. An open wound means any cut, scrape or other abrasion that might allow the bacterium into your body. If there is a chance your wound could come into contact with saltwater or brackish water, marine life, or raw or undercooked seafood while you’re cooking, swimming, fishing, boating or walking on the beach, cover the open wound with a waterproof bandage. If a wound or cut does comes into contact with brackish water or saltwater, raw seafood or its juices, wash it thoroughly with soap and water. If you develop a skin infection, let your health provider know quickly — this is an infection that can spread rapidly. What’s Next: Watch for the infection in unexpected places. Climate change will test all of us in unexpected ways. Vibrio infection is something Americans living in the Northeast may need to watch for now. If you have cancer, are immunocompromised, have liver disease or take drugs to lower stomach acid, doctors say you should not eat raw or undercooked oysters or other raw or undercooked shellfish. (Of course, the same is true for pregnant women.) If you’re handling raw shellfish, wash your hands thoroughly with soap and water afterward.
