FORT COLLINS, Colo. (AP) - Larimer County health officials say this year's outbreak of the West Nile virus is the worst in two decades.
Health officials say 30 people have been infected with virus so far this year and those numbers are expected to climb.
Human infections from the mosquito-borne disease can occur without symptoms or can cause mild or severe illness, fever and aches. Infections can also lead to disability and even death.
