First Veterinary Positive for West Nile Virus in 2012

The West Nile Virus program is reporting the euthanization of a horse due to an active case of West Nile in Northampton County. This case heralds the arrival of West Nile Virus in 2012 and is the earliest report of a horse illness since the disease reached Pennsylvania in 2000. This case also serves as a reminder to vaccinate horses against West Nile Virus. Program staff will conduct surveillance and necessary control measures to reduce the risk of further WNV transmission. The WNV program will begin the full-time monitoring, controlling and testing of mosquitoes in April. Collection and testing of dead birds begins May 1 and can be reported on www.westnile.state.pa.us or by calling (717) 346-8238.
