bird flu

A fourth person in the U.S. has caught bird flu after working with infected cows on a farm.

Scientists found that contaminated milking equipment can harbor the H5N1 virus for more than an hour, increasing the risk of dairy farmers getting infected.

A man in Mexico died after catching the world's first laboratory-confirmed case of H5N2 bird flu in humans. However, authorities think he likely died of existing conditions, rather than the infection itself.

New research in marine mammals suggests the virus is increasingly adapting to mammalian hosts.

This infection, tied to an ongoing outbreak in cows, is the first in the U.S. to cause respiratory symptoms, but not the first H5N1 case in the world to do so.

A dairy worker in Michigan contracted an eye infection on a dairy farm where H5N1 had been identified in cows.

The patient is being treated with an antiviral drug and is believed to have been in contact with dairy cows infected with H5N1 avian influenza.

A man developed symptoms of fever earlier this month and tested positive for highly pathogenic avian influenza.

Unpasteurized milk samples and throat and nose swabs from cows on U.S. dairy farms have tested positive for bird flu, marking the second known cases in ruminants in the U.S.

Over 17,000 southern elephant seal pups were found dead on Argentina's Valdés Peninsula in a horrific mass die off attributed to the deadly H5N1 avian influenza virus.
