New York State has confirmed the second and third cases of West Nile in the state this year.  Remember your mosquito prevention for both your family and your pets.

We are reporting the second and third confirmed cases of West Nile Virus for 2016 in NY. We share this information with everyone because it is important for both you and your clients to take precautions against arboviruses.  In addition to the equine and zoonotic disease threats, arboviruses such as EEE and WNV may impact dogs and other species.  Your clients are well-advised to reduce their animals’ exposure to mosquitoes.
