Summary

Nutrition label

71% Informative

There is no indication that the mutated virus has traveled beyond this patient.

The H5N1 bird flu virus is not the same strain that is transmitting in dairy cattle in the U.S. It is more closely related to a strain in wild birds such as geese in the Pacific Northwest .

The virus becoming better adapted to the human cells is a start, but it wouldn’t necessarily be enough on its own to ignite an outbreak.

The mutations don’t seem to be random and are at important positions where the virus would need to change to survive in its human host.

In the United States , 53 bird flu cases have been identified in humans and there are ongoing outbreaks in dairy cattle, sporadic outbreaks in poultry and wild birds.
