Four recent outbreaks of disease in the west
There are four disease outbreaks among bighorn sheep herds in the news this winter, two in Montana, one in Nevada, and one in Washington State. This is the time of year when bighorn sheep are concentrated so diseases are more easily transmitted.
There has been no mention of where these sheep contracted pneumonia but, as I mentioned in the recent story about this, there is domestic sheep grazing in an effort to control weeds in the nearby mountains. Could this be the cause?
