As noted in previous posts the California strain of the dairy influenza virus has a higher mortality rate among cattle than the initial virus. Apparently dead cattle are piling up and not being disposed of in a biosecure manner.
The esimate is that there are over 1,100 dairy herds in California and 100 have already been confirmed to be infected with more herds detected by California health officials and already submitted for verification.
20% of the dairy herd in the US is in California (over a million cattle).  The mortality rate was initially 2%, but around 15% of the infected cattle are dying in California.  Initially around 10% of the herd was infected at any one time, but now 50% of the herd is found to be infected in some cases.
