Fourteen states and 197 herds have been affected by H5N1 bird flu in US dairy cows.

The outbreak has now spread to three herds in California , the largest milk-producing state in the country.

The virus is thought to spread from cow to cow, as well as from contaminated milking equipment, dirty hands, and boots.

Four dairy farmworkers and 10 poultry farmworkers have contracted the virus behind the dairy outbreak.
