Yosemite National Park said a second person died after staying in Curry Village. It is one of the park's most popular lodging areas.

Officials sent e-mails and letters on Wednesday to 1,000 people who stayed in tent cabins in Curry Village. That's in addition to 1,700 Curry Village guests who had previously been sent such a warning.

It's unclear whether authorities extended the dates of potential exposure beyond June, July and August.
