Parents want more warnings after a brain-eating amoeba killed their boy on a South Carolina lake
His parents had no clue the brain-eating amoeba , whose scientific name is Naegleria fowleri, even existed in Lake Murray, just 15 miles (24 kilometers) west of Columbia.
They found out when a doctor, in tears, told them the diagnosis after what seemed like a fairly regular headache and nausea took a serious turn.
Jaysen, 12, fought for a week before dying on July 18, making him one of about 160 people known to have died from the amoeba in the U.S. in the past 60 years.
As they grieve their son, the boy's parents said they were stunned to learn South Carolina, like most other U.S. states, has no law requiring public reporting of deaths or infections from the amoeba. The lake wasn't closed and no water testing was performed. If they hadn't spoken up, they wonder if anyone would have even known what happened.
'I can't believe we don't have our son. The result of him being a child was losing his life. That does not sit well. And I am terrified it will happen to someone else,' Clarence Carr told The Associated Press as his wife sat beside him, hugging a stuffed tiger that had a recording of their middle child's heartbeat.
Jaysen loved sports. He played football and baseball. He loved people, too. As soon as he met you, he was your friend, his father said. He was smart enough to have skipped a grade in school and to play several instruments in his middle school band in Columbia.
'He either loved you or he just didn't know you,' his father said. 'He was the type of person who could go to a jump park and five minutes later say, 'This is my friend James.''
Friends invited Jaysen and his family for the Fourth of July holiday weekend on the lake, where Jaysen spent hours swimming, fishing and riding on an inner tube that was being pulled by a boat.
'Mom and Dad, that was the best Fourth of July I've ever had,' Clarence Carr remembered his son telling him.
A few days later, Jaysen's head started to hurt. Pain relievers helped. But the next day the headache got worse and he started throwing up. He told the emergency room doctors exactly where he was hurting. But soon he started to get disoriented and lethargic.
The amoeba was in his brain, already causing an infection and destroying brain tissue. It entered through his nose as water was forced deep into his nasal passages, possibly from one of the times Jaysen jumped into the water. It then traveled along his olfactory nerve into his brain.
The amoeba caused an infection called primary amebic meningoencephalitis. Fewer than 10 people a year get it in the U.S., and over 95% of them die, according to the Centers for Disease Control and Prevention .
The amoeba is fairly common. Researchers are still trying to figure out why the infections are so rare. Some people have been found to have had antibodies, signalling they may have survived exposure. Others may die from brain swelling and other problems without the amoeba ever being detected.
The amoeba becomes dangerous in very warm water and for years has been seen almost exclusively in the summer in the southern part of the country. But a few recent cases have popped up in Maryland, Indiana and Minnesota, scientists said.
The CDC said 167 cases of the infection have been reported in the U.S. between 1962 and 2024, and only four people have survived.
Boys seem most susceptible, but researchers don't know if that is simply because they are more likely to jump and dive into the water or play in sediment at the bottom of lakes.
The amoeba can show up in hot springs, rivers and, on rare occasions, in tap water. That's why doctors recommend using sterile water for cleaning nasal passages with a neti pot.
The only way to be completely safe is to not swim in lakes or rivers and, if you do, keep your head above water. Pinching your nose or using nose clips when diving or swimming can keep water out of your nose.
As he sat in an intensive care hospital room with his son, Clarence Carr couldn't help but think of all the people on the lake.
He wondered if any of them had any clue about the microscopic danger in that water.
'There are entire families out there on pontoon boats, jumping off, just like our kids were having the time of their lives,' he said. 'It very well could be their last moments, and they are unaware of it.'

Menopause increases your risk of STIs due to how aging changes your body
Diagnoses for sexually transmitted infections, or STIs, are increasing in older adults. The Centers for Disease Control and Prevention reports the number of people older than 65 diagnosed with chlamydia, gonorrhea or syphilis in the U.S. increased about three-, five- and sevenfold, respectively, from 2010 to 2023. Data also suggests that women older than 50 are at greater risk for HIV than younger women. Explanations for why these infections are so common in older adults include limited understanding of STIs in this age group, infrequent condom use and increased availability of medications for conditions that typically limit sexual activity in older adults, such as like Viagra and Cialis for erectile dysfunction and estrogen creams and tablets for vaginal dryness. Many older adults are reluctant to discuss their sexual history with their partners and health care providers, which contributes to misconceptions that they are monogamous or sexually inactive. In my work as an infectious disease scientist, I examine the largely unexplored biological reasons for why postmenopausal women have increased susceptibility to STIs. My recently published research shows that menopause is associated with loss of the genital tract's protective barrier, an essential defense against the microbial pathogens that cause STIs. Menopause: A natural part of aging Menopause is the stage in a woman's life marked by no menstrual periods for 12 consecutive months. In the U.S., menopause begins on average between ages 45 and 55. It is estimated that by the year 2030, 1.2 billion women worldwide will be menopausal or postmenopausal. Menopause results from a loss of estrogen production from the ovaries, which can diminish vaginal lubrication and vaginal tissue elasticity. This can cause a condition called genitourinary syndrome of menopause, or GSM, which involves symptoms such as vaginal dryness and irritation, painful sex and frequent urinary tract infections. Roughly half of postmenopausal women experience GSM. In addition to these negative effects on vaginal health, research from my lab has found that menopause also compromises the structural integrity of the tissue lining the vagina. The surface of the vagina is composed of multiple layers of epithelial cells that are held together by numerous adhesion molecules, including the proteins desmoglein-1, or DSG1, and desmocollin-1, or DSC1. These proteins strengthen the vaginal lining and restrict pathogen access to deeper tissue, reducing the risk of infection. To explore how menopause affects the vaginal lining, we compared the DSG1 and DSC1 levels in vaginal tissue from postmenopausal and premenopausal women. We found significantly lower DSG1 and DSC1 levels in postmenopausal women. We then surgically removed the ovaries of mice to model the loss of ovarian estrogen production in postmenopausal women. We also detected significantly less DSG1 and DSC1 proteins in vaginal tissue from mice without ovaries compared with mice with intact ovaries. Mice without ovaries also had greater susceptibility to infection with herpes simplex virus type 2, or HSV-2, and were less able to clear chlamydia infection from their lower genital tract. On the other hand, applying estrogen cream to mice without ovaries restored the integrity of their vaginal lining and fully protected these mice from HSV-2 infection. Too important to ignore Fully understanding the behavioral and biological risk factors that contribute to STI susceptibility can help clinicians and public health officials tackle the startling increases in STIs among older adults. Together, our studies show there is a loss of integrity in the vaginal lining after menopause. While additional research is needed, findings from our lab suggest that estrogen-containing compounds used to relieve vaginal irritation and other symptoms of genitourinary syndrome of menopause can also reduce susceptibility to STIs among older adults. In the meantime, health care providers can help reduce the risk of STIs among older adults by consistently counseling them about safe sex practices and offering routine STI screening.

What still causes the plague in the US?
(NEXSTAR) — Northern Arizona recently recorded its first pneumonic plague-related death since 2007. Early last year, Oregon saw its first case of the bubonic plague since 2015. Person-to-person spread of the plague hasn't been seen in more than 100 years in the U.S., but cases occasionally pop up. So what causes them? The plague cases reported in the U.S. today are not exactly the same as those seen in medieval Europe. Between 1347 and 1352 alone, it's estimated that the plague caused the deaths of at least 25 million Europeans. Rats aboard a ship from the Crimea and Asia that docked in Sicily are blamed for bringing the bubonic plague into Europe. Once fleas ran out of host rodents in Europe – those that lacked resistance to the plague also died – they sought out humans. Fungus labeled 'urgent threat' by CDC is spreading rapidly, hospital study finds Eventually, those who were sick or at risk of carrying the plague were isolated and put into quarantine, much like guidance issued during the COVID pandemic. A vaccine in the late 19th century, improved sanitation, better health practices and modern antibiotics have been credited with helping to stop the spread of the plague when it pops up. The U.S. now sees about seven cases annually, on average, according to estimates from the Centers for Disease Control and Prevention. The World Health Organization says most human cases over the last three decades have been in Africa. When cases do occur in the U.S., they're primarily in the West, with most reported in New Mexico and Arizona. Cases have also appeared within the region of southern Oregon, far western Nevada, and California. U.S. cases are, most often, bubonic. There are three main forms of the plague: bubonic (the most common during Europe's Black Death), septicemic, and pneumonic. Generally speaking, plague is brought on by the Yersinia pestis bacterium, with humans and mammals being affected. 'Quiet cracking' is the newest term for a workplace problem — and it's 'pretty pervasive,' expert says The three types of plague present with different symptoms and are caused by different things. Bubonic plague is caused by the bites of fleas that are mostly found on rodents. Symptoms of bubonic plague, the Cleveland Clinic explains, include a sudden high fever; chills; headaches; pain in the abdomen, arms, and legs; and large, swollen lymph nodes that can leak pus. While the bacteria will multiply in the lymph node where it entered the body, it's capable of spreading to other parts of the body if not treated with antibiotics. Septicemic plague has similar symptoms to bubonic plague, including fever, chills, extreme weakness, pain in the abdomen, shock, and the possibility of bleeding into the skin and other organs, the CDC explains. This form of plague can develop from untreated bubonic plague as well as from the handling of infected animals. Should a person with bubonic or septicemic plague go without treatment, and the bacteria reach their lungs, they can develop pneumonic plague. A person can also get pneumonic plague from breathing in 'droplets coughed out by another person or animal with pneumonic plague,' according to the CDC. Like other forms of plague, a person infected with pneumonic plague may develop a fever, headache, weakness, and pneumonia, with the latter developing 'rapidly.' While bubonic and septicemic plague may take a few days to set in, the incubation period for pneumonic plague may be just over a day, the CDC reports. It's the only form that can be spread person-to-person, and it is considered the most serious form of the disease. Between 2020 and 2023, the CDC reported 15 human plague cases were reported. Of those, three died. As the Cleveland Clinic explains, plague has to be treated with antibiotics as quickly as possible — taking antibiotics within 24 hours of symptoms gives you 'the best chance of getting better.' You could begin feeling better within a week or two, as long as you receive treatment, according to health experts. Regardless of the type of plague, about 90% survive with quick treatment. Untreated, 'plague is nearly always fatal,' the Cleveland Clinic said. Health officials have not said how the Arizona resident who died earlier this year of the pneumonic plague became infected. Oregon's case of bubonic plague last year was believed to be brought on by a pet cat. In recent years, Colorado has reported a cat testing positive for septicemic plague and a cat, two prairie dog colonies, and a squirrel testing positive for bubonic plague. Infected fleas are largely to blame for plague cases that occur in the U.S. today, but the handling of infected animals – like cats, rabbits, rats, mice, and squirrels, according to New York's Department of Health – has also been known to lead to the plague. To avoid getting the plague, it's recommended that you take steps to avoid flea bites. That includes wearing bug spray with DEET and clearing up spaces outside where the wild animals fleas love may live. It's also important to speak with your veterinarian about preventing fleas on your pets. Your pets should also not be allowed to roam outdoors freely if you live in an area prone to the plague.

Dangerous waters: What to know about the flesh-eating bacteria and brain-eating amoebas
For most people, swimming in a lake or river is the best way to cool off on a hot summer's day. But there are more than frogs and fish in those waters – microscopic pathogens that can cause serious illness, and in extreme cases, even death, are lurking below the surface. Two waterborne pathogens have been increasing in freshwater lakes and brackish waters across the U.S. in recent years, due to the warming trends of climate change, according to the Centers for Disease Control and Prevention. The culprits are the rare "flesh-eating" bacteria (scientific name Vibrio vulnificus) and the "brain-eating" amoeba (scientific name Naegleria fowleri). In early July, a boy died from the brain-eating amoeba, after swimming in a South Carolina lake. Four other people have died after contracting the rare flesh-eating bacteria in Florida this year, state health officials confirmed. How do these pathogens enter the body? The brain-eating amoeba and flesh-eating-bacteria are known to thrive in warm water environments. The brain-eating amoebas are more commonly found in warm freshwater lakes and rivers, while the flesh-eating bacteria are primarily found in warm brackish water, which is a mix of fresh and salt water. How both pathogens can enter the body during water activities: Why is it called a brain-eating amoeba? The amoeba is often referred to as brain-eating because it can cause an deadly infection called Primary Amebic Meningoencephalitis (PAM) that destroys brain tissue. The brain-eating amoeba usually kills fewer than 10 Americans each year. In particular, only four survivors have been identified out of 167 instances that have been recorded in the U.S. between 1962 and 2024, according to the CDC. Why is it called a flesh-eating bacteria? The bacteria is often referred to as fleshing-eating because it can cause necrotizing fasciitis, which destroys muscle tissue, skin tissue and skin. It can enter through a cut, but it cannot penetrate unharmed skin. The bacteria can also enter your body when you eat uncooked or undercooked shellfish. The flesh-eating bacteria is rare, but it can be life-threatening. Without treatment, death can occur in just a few days. An average of 150 to 200 cases are reported each year, with most of them in Gulf Coast states, according to the CDC. Take these precautions during water activities Swimmers, particularly those in southern states and warm coastal waters, should expect a minimal risk of contracting a pathogen in warm freshwater lakes, rivers, brackish waters and hot springs. How to lower your risks: Medical experts always recommend keeping a close eye on children when they play or swim in the water. While it's uncommon for adults to swallow water while swimming, children are far more prone to do so, according to VCU Health. Researchers are unsure why boys appear to be most at risk of being infected. It may be because they are more prone to play in the sediment at the bottom of lakes or jump and dive into the water, according to the CDC. Progression of infection: Know the symptoms Because of the life-threatening results, it is important to be know of symptoms and significance of seeking immediate medical assistance following any exposure. Here is a comparison of symptoms of the flesh-eating bacteria vs. the brain-eating amoeba: CONTRIBUTING Julie Garisto, T. Sudore and C.A.
