Cook County's Animal and Rabies Control today released an interactive map of locations where bats who tested positive for rabies were found in Cook County this year. The Halloween-themed map is designed to raise awareness about rabies prevention.
“It’s important to remember that a significant number of these bats were found inside people’s homes,” said Dr. Tom Wake, DVM, administrator of Cook County's Animal and Rabies Control. “Pets who primarily stay indoors have the potential to be exposed to rabies. Ensuring your dogs and cats are current on rabies and other vaccinations will help keep them healthy and happy.”
According to Dr. Wake, in 2019 cats were diagnosed with rabies nearly four times more frequently than dogs nationally. “We generally don’t hesitate to vaccinate dogs, but there is a misconception that indoor cats cannot be exposed to the virus, which is simply not true,” he said.
Dr. Wake reminds residents that rabies is, with rare exception, fatal to humans if left untreated. It is transmitted through saliva and spread when an infected animal scratches or bites another animal or human. Six rabid bats have been found in Cook County so far this year.
In the United States, rabies is most commonly transmitted by bats, though only about six percent of weak or sick bats captured by animal control officials in the U.S. test positive for the rabies virus, according to the Centers for Disease Control and Prevention. Other common carriers of rabies include skunks, raccoons and foxes.
The incubation period for rabies is usually one to three months. Symptoms of rabies may include: an extreme or irrational fear of water, drooling, excessive salivation, dizziness, fatigue, fever, loss of appetite, delirium, fear, hallucinations, nausea, vomiting, muscle spasms, paralysis, sensitivity to light and aggression. It is important to seek medical treatment after a bite from an unknown animal.
Rabies in dogs can be seen in two forms – furious and somnolent. In the furious form, dogs are very aggressive and snap at anything around them. In the somnolent form, dogs are weak and unaware. Cats always show the furious form of the disease. Skunks and raccoons often show symptoms that are non-specific.
Cook County’s Geographic Information Systems (GIS) Department created the map using data provided by Animal and Rabies Control. "I'm glad we could use GIS to create a themed interactive map for residents that showcases positive rabies cases,” said Wig Ingente, GIS program coordinator.
