  • The flu season typically coincides with our peak ski season, meaning people congregating at restaurants and ski lodges and other public areas creating the opportunity for flu transmission. Despite 2020's lack of high numbers of flu cases, Residents should protect themselves with the flu vaccine and other common hygiene practices.

Cleaning out your ski cabin? Sprucing up tack room? Cleaning out the attic? If mice can live there, so can the Hantavirus. Hantavirus is uncommonly transmitted to humans, but found in the Northwest Colorado Region. Few cases have been reported in Routt County since 1993. If you think there are mice droppings around, protect yourself by wearing gloves and a dust mask.
