OTC nasal spray seemed to cut COVID infections by 67% in mid-sized trial

Daily squirts of a safe, over-the-counter allergy nasal spray may prevent COVID-19 infections from taking hold, according to results published Tuesday in JAMA Internal Medicine. In a mid-staged trial, the spray appeared to reduce infections by promising 67 percent, though a larger trial will need to confirm that robust efficacy. The trial was a randomized, double-blind, placebo-controlled Phase 2 trial conducted by researchers at Germany's Saarland University between March 2023 and July 2024. T

At Least 2 People Died of ‘Flesh-Eating’ Bacteria After Eating Tainted Oysters

“Flesh-eating” bacteria are continuing to claim lives this summer. Louisiana health officials reported this week that two more people have died from Vibrio infections this month, potentially caused by eating tainted oysters. The Louisiana Department of Health announced the latest deaths during a meeting of the Louisiana Oyster Task Force held Tuesday. Both deaths are linked to oysters harvested in the state, but the oysters were eaten at separate restaurants in Louisiana and Florida. Louisiana

Two men fell gravely ill last year; their infections link to deaths in the ’80s

Four men in Georgia, all living in the same county, mysteriously became infected with a potentially deadly soil bacterium that's normally found in the tropics and subtropics, particularly Southeast Asia and northern Australia. The four cases were tied together not just by their shared location but also by the bacterial strain; whole genome sequencing showed the bacteria causing all four infections were highly related, suggesting a shared source of their infections. But this bacterium doesn't te

Missouri Man Dies After Water Skiing Leads to Brain-Eating Amoeba Infection

A Missouri man’s lake outing has ended in tragedy. Local health officials announced this week that a resident died from a rare but nearly always fatal brain amoeba infection likely caught while water skiing. The Missouri Department of Health and Senior Services disclosed the resident’s death Wednesday, following its initial report of the case last week (though few details about the case were released, several outlets reported the resident was a man). Officials are still investigating the source

Measles Cases Are Soaring in Mexico

The spread of measles is showing no signs of slowing down in Mexico. Between July 21 and 25, the country’s number of confirmed infections in 2025 rose from 3,553 to 3,730, an increase of 197 in only four days, according to the Ministry of Health. Experts and health officials in Mexico have warned that the virus’s speed of transmission appears to be increasing. So far, the outbreak has claimed the lives of 12 people: 11 in the state of Chihuahua—which borders Texas to the north, the epicenter of

Man’s heart stopped after common bacterium caused ultra-rare infection

A 51-year-old man showed up at a hospital in Germany looking as though he was wasting away, with swelling and tenderness in his ankles and knees. Then, his heart stopped. Doctors were able to resuscitate him. Then, they got to work trying to figure out what was wrong. The man told them that for three months he had been suffering from diarrhea, weight loss, joint pain, and fever. His case was reported in this week's issue of the New England Journal of Medicine. Blood tests didn't detect any inf

Kidney Transplant Patient Got Incredibly Rare Infection from Her Cat

An immunocompromised woman’s cat stirred up a lot more trouble than usual (for a cat). In a recent case report, doctors detail how the feline likely spread a seldom-seen bacterial infection that landed its owner in the hospital. Doctors in Slovenia wrote the report, published in the June issue of Emerging Infectious Diseases. The 56-year-old woman, a kidney transplant recipient, developed a severe, rare bout of Mycoplasma arginini infection that was eventually traced back to her cat. Thankfully

A Vaccine for Yeast Infections Could Soon Be Reality

Hold your horses, The Last of Us. Scientists have created an experimental vaccine that could be effective against multiple types of fungal germs, including those that cause vaginal yeast infections. Researchers at the University of Georgia developed the vaccine candidate, code-named NXT-2. In their latest study with mice, NXT-2 appeared to protect the animals from a common culprit of yeast infection, Candida albicans. The team is now planning to forge ahead with human trials of the vaccine. Co
