Two people have died and another was sickened by the
hantavirus syndrome.
The park has sent out 3,000 emails to visitors who stayed in
the Curry Village camping area from June through
August.
Ranger Kari Cobb says part of Curry Village has been closed
off to visitors.
COBB: "We also temporarily relocated all those individuals
who currently have reservations for what we call our signature tent
cabins here in Curry Village in Yosemite National Park."
The disease is carried by deer mice, transmitted by droppings
stirred up by the air.
Both state and federal officials are at the park and trapping
mice to see the extent of the infestation.
Cobb says the park is finding more ways to safeguard
visitors.
COBB: "They have been providing
ways to rodent proof those cabins, they have also give us ways to
clean up after that that keeps us safe."
Some visitors have cancelled reservations, but other walk-in
visitors are filling in the empty campsites.
