A Chicago dog under observation for biting an individual tested positive for rabies, the state’s first confirmed canine case in decades.
According to the Illinois Department of Public Health, the dog bit an individual on December 11, and was held in accordance with state law.
Due to the dog’s behavior, it was euthanized on December 18, and tested positive for rabies on December 19 at a Chicago laboratory, officials said.
According to the IDPH, the dog was the first in the state to test positive for rabies since 1994, and is the first to test positive in Cook County since at least 1964.
