YOSEMITE NATIONAL PARK, Calif. (AP) - Yosemite National Park officials say a second person has died of a rare, rodent-borne disease after visiting the park earlier this summer.

Spokesman Scott Gediman says this weekend health officials learned of a second death of a person who contracted hantavirus after visiting the park in June.

There is one other confirmed case of the illness, and a fourth is being investigated.

Park officials are warning visitors who stayed in tent cabins at Curry Village from mid-June through the end of August to beware of any symptoms of hantavirus, which can include fever, aches, dizziness and chills.

Federal health officials say symptoms may develop up to 5 weeks after exposure to urine, droppings, or saliva of infected rodents.
