Newer Bird Flu Strain Detected In Dairy Cattle

This marks the first time this strain has been found in dairy cattle.

A newer strain of the H5N1 bird flu virus has been detected.

Six dairy herds in Nevada have tested positive for the variant that has been associated with severe infections in humans.

The strain is not the same one that has been circulating in other dairy herds nationwide.

The newer version has previously been detected only in birds and in people who came in contact with infected birds.

This marks the first time this strain has been found in dairy cattle, meaning these cows caught it from wild birds, instead of another infected herd.

The situation hints that the bird flu infection could continue spreading.
