Health officials on Wednesday warned of an increase in the number of rodents that have tested positive for hantavirus in the areas of Riverside County.
A visitor to Yosemite National Park has recovered after becoming the ninth person diagnosed with a deadly rodent-borne illness blamed for three deaths among those who spent time at the park this summer, officials said Thursday.
Up to 10,000 people who were guests in certain lodging cabins at Yosemite National Park might have been exposed to a deadly mouse-borne virus, park officials confirmed Friday.
Two more Yosemite National Park visitors have been found with a mouse-borne virus blamed for the deaths of two people, bringing the total number of infections to six, state health officials said Thursday.
Health officials are warning 1,700 Yosemite National Park visitors that they may have been exposed to hantavirus.
Yosemite officials told 1,700 past visitors on Tuesday they may have been exposed to a rodent-borne disease already blamed for the deaths of two people who stayed at the park.
The county Department of Environmental Health said six rodents in the past week have tested positive for the potentially fatal but difficult to contract virus.
