Episode 27: Neuro Invasion - The Silent Siege of West Nile Virus
Update: 2025-09-10
Description
West Nile virus is back in the headlines, with new human cases in the U.S. and steady activity in Europe. In this episode of Infectious Dose, Heather tracks the current outbreak season through CDC and ECDC surveillance and state-level reports, explores how the virus cycles between birds and mosquitoes, and examines what happens when you get infected. Most infections are silent, but for a small fraction, West Nile unleashes a devastating attack on the nervous system. With no proven treatments and no human vaccine, prevention remains our best defense—making this one of the most enduring mosquito-borne threats in the U.S. and beyond.
