Current strains of bird flu are “poorly suited for pandemic potential,” said Dr. Shira Doron, a Tufts Medicine infectious disease expert.

Avian flu is rampant in poultry farms and in wild birds in the U.S. Every mutation brings the virus one step closer to the brink of human-to-human transmission, but predicting whether a virus will cross that threshold remains an uncertain science.

America should have more aggressively intervened almost a year ago.

Farmers, animal rescues and zookeepers in Rhode Island are taking precautions to protect animals, their workers and the general public from bird flu.

The first person in the U.S. just died from a strain of the virus in Louisiana, but there’s still some simple ways to stay safe.

The bird flu, which seemed to be fading away, has once again set off alarms. With the first death recorded in the United States and the virus detected in every state, the situation is becoming increasingly complex.
