Potential Rabies Exposure at Grand Teton National Park

Hundreds of visitors might have come into contact with rabies during a stay at a cabin in Grand Teton National Park, Wyoming.

The exposure concerns arise from bats discovered in one of the cabins at Jackson Lake Lodge, affecting individuals from various states and even other countries. Reports indicate that health officials are trying to reach out to those who might have been at risk.

As of Friday, one of the bats found on the premises hasn’t tested positive for the virus, but authorities are actively alerting potentially affected individuals.

People are being cautioned about the possibility of unnoticed bites or scratches from the creatures, as even minor injuries can lead to health risks.

The cabin has been closed since late July when the lodge became aware of the bat situation. The cabins had been operational throughout the winter and reopened in May. Health officials estimate that around 500 guests may have stayed in the affected cabin due to an estimated 250 bookings before the end of July.

Bats have been identified in multiple rooms, sparking further investigation. Health authorities have advised precautionary measures, especially for those who may not have recognized the signs of bat encounters, like deep sleepers or very young children.

While state health officials express no ongoing concerns about visitor safety at the lodge—highlighting that events like the Federal Reserve Economic Policy Symposium occur there every summer—there’s still some caution warranted.

Rabies can be a serious virus affecting mammals, including humans, primarily targeting the central nervous system. If left untreated before symptoms arise, it can lead to severe brain disease and death. Bats, in particular, pose a unique risk since their bites can be small and often go unnoticed. The symptom onset period can also vary significantly, ranging from weeks to months post-exposure.

According to Emily Cullen, a public health veterinarian in Wyoming, three or four deceased brown bats from the area have tested negative for the virus.

The National Park Service is not considering eradication of the bats but is implementing measures to prevent their re-entry into the building after they leave for feeding.
