Bourbon virus is a rare, potentially fatal infection spread by the Lone Star tick. According to the Centers for Disease Control and Prevention (CDC), there is currently no known cure or vaccine for Bourbon virus. Bourbon virus is a tickborne disease that was first detected in 2014 in Bourbon County, Kansas. In other words, because Bourbon virus is a virus, none of the treatments that work against the diseases listed above will treat it. While cases of Bourbon virus are increasing across the country, this is still considered a rare disease, Russo says.
