Hundreds possibly exposed to rabies at bat-infested cabins in Wyoming national park
Health officials are working to notify hundreds of people across 38 states and seven countries who may have been exposed to rabies after staying in bat-infested cabins at Wyoming’s Grand Teton National Park.
The alert follows the discovery of a bat colony in the attic above eight cabins at Jackson Lake Lodge. Although none of the bats tested so far have been positive for rabies, experts warn the risk can’t be ruled out. Most of the bats never entered guest rooms, but some did — and that’s where concern arises.
“People may not realize they’ve been bitten or scratched, especially if they were asleep,” said Dr. Alexia Harrist, Wyoming State Health Officer. “We’re urging anyone who saw a bat in their cabin or suspects contact to talk to their doctor immediately.”
Rabies is nearly always fatal once symptoms appear, but a five-dose post-exposure vaccine series is highly effective if given promptly.
The cabins — numbers 516 through 530, even numbers only — were opened for the summer in May and closed on July 27 after the issue was discovered. Health officials estimate up to 500 guests may have stayed in the affected units.
Those at highest risk include children and deep sleepers who may not recall bat encounters. Authorities are contacting potential visitors through state health departments and the CDC.
While a few dead bats tested negative for rabies, the full extent of the infestation remains unclear. All bats found were brown bats — either “little” or “big” — species common in Wyoming and known to form colonies of up to 100.
“There’s just no way to rule out rabies risk for every bat involved,” said Emily Curren, Wyoming’s public health veterinarian.
Grand Teton Lodge Company has since sealed off entry points to prevent the bats from returning, and there are no ongoing safety concerns for visitors, including attendees of the upcoming Federal Reserve symposium scheduled for August 21–23 at the lodge.
No extermination is planned. Instead, one-way devices are being used to let bats leave the building without returning.
