The Powassan virus, a serious but rare disease, has caught headlines in recent months as cases have popped up and sometimes been fatal in the Northeast. It can cause fever, headache, vomiting, weakness and memory loss, according to the Centers for Disease Control.

There was a lot of press attention after that and of course there have been a few human cases. We have no evidence that Powassan virus can cause illness in companion animals, livestock or wildlife. However, we are screening for it in clinical samples because we just don’t know very much about the virus in animals.”
In general, cases of Powassan are rare. Between 2006 and 2015, there were between one and 12 cases per year in the U.S., according to the CDC.
There have been no positive cases of Powassan in Tompkins County, according to the Tompkins County Health Department. However, physicians are being advised to order a…
