bird flu

So far, all nine cases reported nationally this year at dairy and poultry farms have been mild, consisting of respiratory symptoms and eye irritation.

The worker, who had direct contact with infected cows, experienced an eye infection and has since recovered after receiving antiviral treatment.

Experts fear human exposure to the virus can cause it to adapt and spread among humans and create a pandemic. For now, the risk is low.

Health authorities say the man died from a type of bird flu called H5N2 that has never before been found in a human. It isn't known how the man became infected.

The spread of an avian flu virus in cattle has again brought public health attention to the potential for a global pandemic. Fighting it would depend, for now, on 1940s technology that makes vaccines from hens’ eggs.

The dairy worker had mild eye symptoms from the infection and has recovered, health officials said. The worker had been in contact with cows presumed to be infected.

The virus is deadly for birds, but humans aren’t necessarily at risk for infection despite one case in Colorado.

Three genetic changes could be enough to make a bird flu strain that's already killing some people in China highly contagious. Are experiments with a deliberately mutated version too risky?

A type of bird flu that appeared in China a few months ago has infected more than a hundred people. Some scientists are worried that this virus has the potential spread globally. But a look at the virus's genes suggests the pathogen doesn't have the typical features of pandemic.
