Nature reports that genetic (RNA) evidence shows H5N1 bird flu has been circulating among US dairy cows for months. The findings suggest the outbreak in cattle went undetected for longer than previously recognised.
The report focuses on the virus's spread within herds.
Longer undetected spread in dairy herds raises the likelihood of ongoing milk production losses and tighter surveillance. This is a disease development with limited direct effect on feed prices.
