The USDA is listing 2 more dairies infected in Nevada.  That likely 
makes 9 herds detected in the latest D1.1 oubreak (one detection of the 
original B3.13 dairy virus in Dec for 10 total herds listed for Nevada). 
  The rapid spread of the D1.1 infection likely means that dairy workers 
are spreading the virus to more herds because it is unlikely to be dairy 
cattle movements that were likely restricted in Dec with the first dairy 
infection detected.  The USDA and CDC continue to refuse to test dairy 
workers and stop the spread of the infection by limiting dairy worker 
movements between farms.  Google says that Nevada has "just over 20" 
dairy farms ranging in size from 500 to 25,000 cows.  This means that 
half the herds are already infected, and they still are not doing 
anything to stop the spread in terms of testing the dairy workers and 
restricting their movements.  It is what they needed to do in
