Flesh-Eating Bacteria Incidents Reported, Experts Warn Warming Oceans Could Make It More Common
Within the last month, at least two people in the U.S. have contracted a flesh-eating infection from an ocean-dwelling bacterium — an occurrence that experts warn could become more frequent as the world's oceans warm.
Vibrio vulnificus is an "opportunistic pathogen" responsible for a majority of seafood-related deaths in the U.S., according to an article written by the American Society for Microbiology. The bacteria thrive in warm salty and brackish waters and enter humans either through breaks in the skin or after being consumed with raw seafood. Up to one-third of people with vibrio vulnificus will die from the infection, which can cause a flesh-eating and commonly fatal bacteria known as necrotizing fasciitis.
A woman in Florida died last month after contracting the bacteria when she fell into the water and cut her leg — a wound that measured just three-quarters of an inch, NBC reported. That afternoon she experienced overwhelming pain in her leg. Within days her limb was black and she was put on hospice care, eventually succumbing. She was diagnosed with necrotizing fasciitis and subsequently suffered from two strokes, kidney failure and sepsis.
At another Florida beach, a 12-year-old girl similarly complained of pain that started in her leg and traveled through her entire body, wrote her mother in a Facebook post. After an initial visit at a local hospital, doctors told the woman to send her daughter to a hospital in Indianapolis specializing in children's health where she was admitted to the ICU for an infection behind her knee and septic shock, reports Today. Though her recovery is expected to be a long one, a rush to emergency surgery saved the girl's life and prevented the amputation of her leg.
"We are not completely better, but we are on the road to recovery. We will have numerous doctors' visits, physical therapy and blood work to continue, but all that matters is my girl is ALIVE. I wanted to share her story in hopes that it may help save someone else. It is CRITICAL to be aware of the signs and symptoms and getting treatment quickly," she wrote.
Cases in 2019 are adding up at a rate much higher than in previous years: A young boy contracted vibrio in Maryland last week after swimming at a local beach, reports CBS. The Miami Herald reports the story of a man in Florida who contracted the flesh-eating bacteria and whose quick action similarly saved him from losing muscle tissue in the arm. Surprisingly, the man insisted that he became infected without being in the water.
Necrotizing fasciitis can be caused by a number of different bacteria, but is commonly caused by V. vulnificus when people wade into contaminated water with a cut or wound or eat raw shellfish infected by the bacteria. Endemic along the Southeast U.S. coast, the bacteria doesn't typically extend north of Virginia's Chesapeake Bay. However, a study published in the Annals of Internal Medicine suggests that as temperatures rise and make previously cooler regions more hospitable to the warm-water bacteria, infections will also increase in non-endemic areas
The researchers reported five occurrences of necrotizing fasciitis caused by V. Vulnificus in New Jersey during the summers of 2017 and 2018. By contrast, just one case had been diagnosed in the previous eight years, researchers told Medscape Medical News.
The quick-spreading infection starts with a red or swollen area of skin, severe pain and a fever, says the Centers for Disease Control and Prevention. Later symptoms can include ulcers, blisters, or black spots on the skin, changes in its coloration, pus or oozing from the infected area, as well as dizziness, fatigue, and diarrhea or nausea. Treatment requires hospital and intravenous antibiotics and surgery to reduce the rapid spread by removing the dead tissue to avoid sepsis, shock, and organ failure, as well as life-long complications for loss of limbs and severe scarring.
Correction: A previous version of this article stated that three people were infected by a flesh eating bacteria. Two were infected, while a third was infected with vibrio vulnificus. The headline and story have been updated for clarity.

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
