In this undated photo provided by DNC Parks and Resorts at Yosemite, Inc., is the interior of a signature tent cabin at Yosemite National Park in California. Yosemite officials are expanding their efforts notify visitors to a complex of tent cabins who may have been exposed to a rare but potentially deadly rodent-carried virus. Officials said Wednesday they have notified 2,900 visitors who stayed in the Curry Village "Signature Cabins" since mid-May, up from 1,700 initially notified.
