Jamestown Canyon Virus in Connecticut: Lessons Learned from 24 years of Surveillance and Research

Wednesday, September 23, 2020
1:00 p.m. (Eastern Time)

Presented by: Philip M. Armstrong, ScD, Virologist/Medical Entomologist, Department of Environmental Sciences Center for Vector Biology & Zoonotic Diseases The Connecticut Agricultural Experiment Station


Jamestown Canyon virus circulates in a mosquito-deer transmission cycle and is broadly distributed throughout North America. Infection in humans occasionally results in neurological illness and the number of reported human cases has risen sharply in the northeastern and midwestern US during the past decade. Researchers at the Connecticut Agricultural Experiment Station have trapped and tested mosquitoes in Connecticut since 1997, and have sequenced and analyzed numerous isolates of Jamestown Canyon virus obtained during statewide surveillance. In this presentation, Dr. Armstrong will discuss major findings from these studies and explain its relevance to understanding the ecology and epidemiology of this under-studied virus.
