A man from Lake County, Illinois died from rabies a month after he woke up to find a bat in his room, biting his neck. It marks the first human case of the virus in the state since 1954.

According to the Illinois Department of Public Health, the man, who was in his 80s, declined postexposure treatment for the disease despite testing positive. A month after exposure, the man experienced debilitating neck pain, headache, numbness in his fingers, and difficulty speaking and controlling his arms, health officials said. The department said other people also had contact with secretions from the man and had to be given rabies preventative treatment.

The bat reportedly was part of a larger colony that was living inside the man’s home.
