A second park visitor has died from hantavirus at Yosemite National Park.
Nearly 2,000 past visitors are getting warned they may have been exposed to the rare, rodent-borne disease.
There's at least one other confirmed case of the illness and other possible cases are being investigated.
The symptoms are flu-like aches and pains. Officials are urging anyone who’s visited the park who is experiencing those symptoms to see a doctor immediately.
