 The transmission is likely due to some very indirect epidemiology links, such as shared personnel between the different locations. 20% of affected dairy employees and 70% of dairy employee family members work on other dairies. So when you're going from one place to the other, if you're not following careful biosecurity procedures, that will be part of the problem. 7% of affected dairy employees also work on a poultry operation. So now you have that potential connection between the dairy and the poultry.
