Health officials say a 28-year-old Alamosa County woman has died of hantavirus in the first Colorado case of the respiratory disease this year.
Health officials are investigating the source of her infection.
Epidemiologist John Pape (POP-ee) with the state health department says a preliminary investigation indicates she contracted the virus in her home.
The woman, whose name and hometown were not released, died Friday.
Hantavirus is commonly spread through exposure to infected deer mice. Humans can be infected by inhaling the virus during direct contact with the mice or if dust or feces from mice nests is disturbed.
