Officials in Wyoming have said a woman who was bitten by a bat has died after contracting what is believed to be the state’s first case of rabies.

Reports said a 77-year-old woman from the town of Lander became infected after being bitten in August.

She began showing symptoms weeks later and was treated at a Lander hospital. She was recently transferred to a Salt Lake City-area hospital, where officials say she died on Saturday, the Daily Ranger newspaper reported.

The woman has not been identified.
