Powassan Virus (POWV), also known as Deer Tick Virus (DTV), is a member of the same family of viruses as West Nile Virus, Dengue Fever, Zika, and Hepatitis C. and is found mostly in the northeast United States as well as the Great Lakes area.
Symptoms of POWV infection are very similar to those of Lyme disease, but reportedly can be more severe. The Powassan virus attacks the nervous system and can cause encephalitis or meningitis. Serious infections can result in muscle weakness, headache, confusion and even seizures. Ten percent of POWV encephalitis infections are fatal. Long-term neurologic effects that mimic those of Post-Treatment Lyme Disease Syndrome (PTLDS) have been reported.

Through our research, we were first to identify that the tickborne flavivirus Powassan/Deer Tick (POWV/DTV) Virus can commonly be found as a co-pathogen in ticks infected with Lyme disease borrelia with evidence that both the Lyme borrelia and POWV/DTV can be concurrently transmitted to humans from the bite of the deer tick I. scapularis.
