A third person has died as a result of the Hantavirus outbreak in Yosemite National Park.
So far eight people who stayed in the park's Curry Village this summer were exposed to the potentially deadly mouse-born virus. Three people have died and the other five are either improving or recovering.
Six of the cases are from California, the other two are from Pennsylvania and West Virginia.
Park officials are working with other state and public health offices to heighten public health awareness and detection of the disease.
