1 dead, multiple people sickened in Legionnaires' disease cluster in New York City
The New York City Department of Health said July 30 that it is investigating the cluster, which has left one dead and 22 others sick in Central Harlem.
Legionnaires' disease is a severe pneumonia caused by a type of bacteria called Legionella, according to the CDC.
The risk to most people is low, and the disease is not contagious, the agency said. Some people, including those older than 50, smokers or those with a weakened immune system, are at higher risk for the disease, according to NYC Health.
NYC Health said it believes the source of the bacteria causing this cluster is a cooling tower in the area. Here's what to know.
Where is NYC Legionnaires' cluster?
The Legionnaires' disease cluster is in Central Harlem. According to NYC Health, the following zip codes are affected:
People who live or work around these ZIP codes and develop flu-like symptoms should see a health care provider right away, the agency said.
What caused NYC Legionnaires' cluster? Is water safe to drink?
NYC Health said the likely source of the bacteria causing the Legionnaires' cluster is a cooling tower in the area.
Cooling towers, which are water systems typically found on the top of buildings, spray mist that can contain the bacteria that causes Legionnaires' disease, the agency said.
All of the cooling towers in the affected area are being tested for the bacteria, the health department said.
The health department also said the cluster does not involve any building's plumbing system, meaning it is safe to drink water, bathe, shower, cook and use air conditioners.
What is Legionnaires' disease?
Legionnaires' disease is a type of pneumonia caused by consuming water or mist contaminated with Legionella bacteria, according to the CDC. Symptoms of the disease, which can take up to 14 days after exposure to show up, include:
The disease can be treated with antibiotics, and most healthy people who get infected usually get better, but complications are possible. About 1 in 10 people who get Legionnaires' disease die from it, according to the CDC.
How to stay safe from Legionnaires' disease
Legionnaires' disease is a waterborne illness, so the CDC recommends cleaning pipes and devices that use water to remove germs and debris.
Prevention methods include flushing showerheads and faucets that haven't been used recently, and regularly cleaning devices that use water, per the CDC.
Owners of cooling towers, decorative fountains and hot tubs should follow manufacturer instructions for cleaning, disinfecting and maintenance, the CDC said.

Utah vaccine exemption rate rises to No. 2 in nation
Utah now has the nation's second highest rate of vaccine exemptions for kindergartners, as the state's share of fully immunized children continues to drop. Threat level: Utah's kindergarten vaccination rates have long fallen below the 95% needed for herd immunity against highly contagious illnesses — and kids are about to return to school amid a measles outbreak. As of fall 2024, just 88.6% of Utah kindergartners were up to date on their measles-mumps-rubella (MMR) vaccines, per new CDC data. Whooping cough was at 88.1%. Meanwhile, whooping cough is spreading in southwest Utah, health officials announced last week. What we're watching: Kindergarten vaccination rates in parts of Utah are dropping toward the 80% herd immunity threshold for polio, per the latest data from the state health department. More than 19% of kindergartners in southwest Utah were not fully vaccinated for polio, with nearly 15% in the central counties. The big picture: Anti-vax sentiments — once considered a liberal trend — gained ground on the political right amid hostility toward COVID prevention measures. A Gallup poll last year found that 69% of respondents viewed childhood vaccines as "extremely" or "very" important, down from 94% in 2001 — a drop researchers attributed to those who lean Republican. By the numbers: More than 10% of Utah kindergartners obtained immunization waivers last fall, up a full percent from the previous year. Only Idaho had a higher rate of exemptions, at 15.4%. The intrigue: Of the 10.3% of Utah kindergartners who sought exemptions, just 0.3% were for medical reasons. About 85% were for "personal" reasons, with "religion" accounting for another 12.5%. Catch up quick: A 2022 Axios analysis of Utah immunization data by ZIP code showed exemptions after 2020 largely spiked in politically conservative areas. Caveat: Vaccine waivers are far more common among online students, covering more than half of the state's nearly 1,500 online kindergartners. Of the 44,000 in-person kindergartners, 9% had exemptions, up from 7.9% a year before. Another 1% were out of compliance — neither vaccinated nor exempt. Flashback: Trump cut more than $30 million in Utah childhood immunization funding in April. Zoom in: Salt Lake County's exemption rate was the lowest of any local health district in the state at 5.5%.

New Lyme Blood Test Bests Standard Diagnostics
A new blood test for Lyme disease outperforms standard diagnostic testing across all stages of the disease, according to new data presented at the 2025 Association for Diagnostics and Laboratory Medicine annual meeting in Chicago. The test, which pairs a multiplexed assay with a machine learning algorithm, showed over 90% accuracy in diagnosing Lyme disease in 308 human serum samples. The CDC estimates that about 476,000 individuals may be diagnosed and treated for Lyme disease each year in the US. The tick-borne disease, caused primarily by infection with Borrelia burgdorferi , is most treatable in the first few weeks of infection, but diagnosis during this early stage poses a challenge to clinicians. Barriers to Early Diagnosis The most common sign of early infection is a skin rash called erythema migrans (EM) that often occurs at the site of the tick bite. While a bull-eye-shaped rash is telltale sign of Lyme disease, this type of EM is actually not a common presentation, said Liz Horn, PhD, MBI, principal investigator of the Lyme Disease Biobank, a biorepository of samples from people with Lyme disease, headquartered in Portland, Oregon. She was not involved with the work. EMs can present in different forms, and about 30% of people with Lyme disease do not develop a rash. 'If you don't have a rash, you have to rely on serologic tests,' Horn said, which are notoriously insensitive in early disease, as antibodies can take weeks to develop. The CDC currently recommends a two-test format. Standard two-tier testing (STTT) involves an enzyme immunoassay as the first step, which, if positive or indeterminate, is followed by a Western Blot. In the first few weeks of disease, antibody levels can be too low to detect, leading to false negatives. In a recent study led by Horn using samples from individuals with signs and symptoms of early Lyme disease who were enrolled in the Lyme Disease Biobank, just 34% of patients presenting with EM > 5 cm tested positive on serologic tests. Among patients without EM, only 16% had positive results, and among those with EM ≤ 5 cm, the positivity rate dropped to just 5%. 'If we could get a serology test that works better in early disease, that could have great benefits for both patients and providers,' Horn said. Pairing AI With a Multiassay This new blood test, called LymeSeek, works differently by detecting 10 different antigens simultaneously. An algorithm developed using deep learning 'sorts through all of the responses,' explained Holly Ahern, MS, MT, the chief scientific officer of ACES Diagnostics, the company developing LymeSeek, in Paradise Valley, Arizona. 'That is what gives the test its very high sensitivity and specificity,' she said. Ahern is also an associate professor of microbiology at State University of New York at Adirondack (SUNY Adirondack) in Queensbury, New York. To validate the test, developers analyzed the human serum samples of 150 control individuals and 158 Lyme disease cases, across all phases of Lyme disease. Samples were provided by the Lyme Disease Biobank, the CDC, and the Johns Hopkins University Lyme Disease Research Center in Baltimore. The control samples were from patients in endemic and nonendemic areas and included individuals with non-Lyme look-like diseases, like mononucleosis and rheumatoid arthritis. The test correctly classified 281 samples as Lyme cases or control individuals, resulting in a test sensitivity of 91.7% and a specificity of 90.7%. In an additional analysis, the ACES diagnostics team also compared LymeSeek to STTT using samples from the Johns Hopkins Lyme Disease Research Center. In very early stages of disease (0-72 hours after appearance of an EM rash), LymeSeek diagnosed 100% of Lyme cases, whereas standard testing identified only 37% of cases. In samples taken 3-4 weeks after EM appearance, LymeSeek's results remained consistent, and standard testing identified 76% of cases. 'The observed seroconversion indicates the enrolled patients did have Lyme disease and is a confirmation that the test result given by LymeSeek is a true positive test result,' Ahern added. In patients with post-treatment Lyme disease (6 months or more after infection), LymeSeek identified 97% of cases, whereas standard testing identified less than half (46%). 'With this one single test, we can detect [Lyme] in the early stages, but we can also detect it across all stages of the disease' Ahern said, which includes through 1 year from first Lyme diagnosis. ACES Diagnostics is now working to develop a clinical trial plan with the FDA. The test has received a De Novo classification, meaning it's being evaluated on its own merits rather than compared to the current standard diagnostics. 'We're not just showing that we are as good as two-tier serology because what's the point of being as good as a test that really isn't very good?' Ahern said.

Teenager and Toddler Contract Parasite Spread by Exposure to Raccoon Feces
The two unrelated children were hospitalized and treated for B. procyonis infectionsNEED TO KNOW Two California children contracted a rare parasite commonly spread by raccoon feces and occasionally by dogs The two unrelated kids — a teenager and a toddler — were hospitalized and treated for B. procyonis infections in 2024 The Centers for Disease Control and Prevention (CDC) says people should "avoid contact with raccoons and their feces"Two children in California contracted a rare parasite that is commonly spread by raccoon feces and occasionally by dogs. The Centers for Disease Control and Prevention (CDC) detailed two 2024 cases of a B. procyonis infection found in two unrelated children — a 14-year-old boy and a 15-month-old boy — in its latest Morbidity and Mortality Weekly Report, published on Thursday, July 31. The infection, commonly referred to as raccoon roundworm infection, is caused by the Baylisascaris procyonis roundworm, which is often spread by exposure to raccoon feces and can also be transmitted to dogs in rare cases. According to the report, the Los Angeles County Department of Public Health (LACDPH) was notified last year of two patients with neurological signs and symptoms — such as behavioral change, lethargy and "gait instability" — consistent with the infection. Both cases were in the South Bay area of Los Angeles County, according to a LACDPH release from September 2024. According to the CDC, raccoons can "shed millions of roundworm eggs in their feces every day," which then become infective after a few weeks and can develop into larvae when consumed by "nondefinitive hosts." There have only been 35 cases in humans reported in the U.S., the health organization said. The teenage boy, who is autistic, had a history of ingesting non-food items and was initially hospitalized in May 2024 due to a series of "behavioral changes," according to the new information from the CDC. After "enhancing" lesions were detected in the boy's brain, doctors discovered and treated what the CDC called "a live parasitic nematode" in his eye. The teen was prescribed medication for a six-week period, before symptoms "subsequently resolved" and he returned to his "baseline neurologic status," according to the agency. The second patient, a toddler, was also hospitalized that June, before a brain MRI found "diffuse white matter abnormalities." Months later, doctors eventually discovered a "live parasitic nematode" in his eye — which, like the older boy, was treated with a laser. Both boys were also treated with a drug for paramedic worms, albendazole and the anti-inflammatory corticosteroids. While a source of the infection was not clear for the toddler, the CDC reported that a raccoon latrine — or an area where the animals defecate — was located on the rooftop of the teenager's home, "directly above the entrance to the premises, allowing feces to roll onto the landing below." The child was suspected to have consumed the feces or feces-contaminated soil. Due to the extent that raccoons visit the home, and unsuccessful efforts to move the animal's latrine, the family is planning on moving, the CDC said. "Given the severity of disease in humans, the high prevalence of B. procyonis infection in raccoons, and the proximity of raccoons to humans and pets, B. procyonis is a substantial public health concern," the CDC said. "To prevent infection, the public should avoid contact with raccoons and their feces, not keep raccoons as pets, ensure that children or persons with developmental disabilities do not place contaminated objects or fingers into their mouths, practice good hand hygiene after outdoor activities and safely remove raccoon latrines on properties, paying special attention to flat surfaces such as rooftops, decks, tree stumps, or unsealed attics and other areas where raccoons prefer to defecate," they continued. Since dogs can also be infected, the CDC encourages dog owners to prevent their pets from eating raccoon feces and said pets should be treated with a "year-round parasite prevention product."
