In more bad news about antibiotic resistance, new research suggests that people and their pets may be able to transmit multidrug-resistant germs to each other.

Still, cases of cross-transmission are rare and it's not clear if pets are giving germs to people or people are giving germs to their pets, the study authors noted.

"In urban areas in high-income countries, pets do not seem ...

A new theory about the start of the COVID-19 virus points to illegally traded raccoon dogs at a market in Wuhan, China.

A strain of avian (bird) flu appears to be killing seals off the New England coast, heightening fears among scientists that mammal-to-mammal transmission could be happening.

If so, it would be a step towards something health experts have long dreaded: A strain of H5N1 bird flu that might spread easily among people, with potentially devastating effects.

    The findings were published March 9 in

    Some people may have a gene that helps protect them from respiratory diseases like COVID-19 -- and helped their ancestors fight the plague.

    It comes at a cost.

    This same gene variation may be linked to an increased risk of autoimmune disease, including rheumatoid arthritis and inflammatory bowel disease, according to British researchers.

    “This gene essentially chops up prote...

    U.S. Federal health officials have issued recall notices for two more brands of eyedrops.

    In the latest round of recalls, the U.S. Food and Drug Administration posted notices after the companies voluntarily pulled several lots of their eyedrops from the market.

    Two major pharmaceutical companies published clinical trial results this week that pave the way for an RSV (respiratory syncytial virus) vaccine to be avail...

    HBO’s hit series “The Last of Us" envisions a world decimated by a fungal apocalypse.

    A real-life insect fungus called Cordyceps makes the leap into humans, turning those stricken into violent zombie-like creatures that spread it to others through bites. Society collapses in a matter of days after the fungus emerges.

    Kidney disease patients on dialysis are 100 times more likely to contract a dangerous blood infection than people not receiving the treatment -- and that risk is borne primarily by Hispanic and Black Americans, U.S. government health officials say.

    Hispanic patients are 40% more likely than white patients to develop a staph bloodstream infection while on dialysis, according to a new

    While COVID-19 variants Alpha, Gamma and Delta are no longer circulating among humans, they continue to spread in white-tailed deer.

    The animals are the most abundant large mammal in North America. Scientists aren’t sure whether the deer could act as long-term reservoirs for these obsolete variants.

    In a new study, researchers at Cornell University, in Ithaca, N.Y., collected 5,...

    Having sepsis -- a life-threatening response to infection -- may put patients at risk for future heart failure and rehospitalization, according to a new study.

    As colds, flu and COVID continue to circulate this winter, a new U.S. government study finds that young children infected with COVID plus a second virus tend to become sicker.

    While the origins of smallpox has remained a mystery for centuries, researchers now believe that it dates back 2,000 years earlier than previously thought.

    Until recently, the earliest genetic evidence of smallpox, the variola virus, was from the 1600s. And in 2020, researchers found evidence of it in the dental remains of Viking skeletons, pushing its existence 1,000 years earlier.

    Despite routine use of a childhood vaccine, the United States still sees outbreaks of mumps. Now, a new study reinforces the belief that it's due to waning immunity post-vaccination.

    One of the hallmarks of a COVID-19 infection has been a lost sense of smell after the infection ends.

    In a new study, researchers blame an ongoing immune assault on the olfactory nerve cells — cells found at the top of the nasal cavity — and a decline in the number of those cells. The study was led by a team at Duke Health in Durham, N.C.

    “One of the first symptoms that has ty...
