As we were watching episodes of “1923” about a wolf with rabies, an email from the McHenry county Health Department about the subject appeared in my inbox:
Bat in McHenry County tests positive for rabies, first of 2025 season
MCHENRY COUNTY, IL – The McHenry County Department of Health (MCDH) has confirmed that a bat found inside a Ringwood home has tested positive for rabies.
The bat was collected by the MCDH’s Veterinary Public Health division (McHenry County Animal Control) and sent for testing.
In this instance, it was confirmed there was no human exposure, so rabies post-exposure prophylaxis (also referred to as PEP) is not recommended.
The MCDH is therefore sharing this for educational purposes and to remind residents what steps to take if they encounter a bat.
Bite and scratch exposures from a bat can be very small and may go unnoticed.
Therefore, McHenry County residents who find a bat in their home, encounter it, or were in the same room as the bat while sleeping should confine the bat to an enclosed room by closing the door and sealing any gaps at the base with a towel.
If the bat is in a main living area and there has been potential exposure to a person or pet, place an upside-down bucket over the bat, if possible, to contain it. In both situations, residents should immediately contact McHenry County Animal Control at (815) 459-6222 to arrange for the bat’s collection, and potential testing following an exposure risk assessment by the MCDH’s Communicable Disease Program.
For rabies testing, it is crucial that the bat be in good condition (i.e., head intact) and either alive or recently deceased.
If you have questions or concerns about rabies exposure, please contact the MCDH’s Communicable Disease Program by calling (815) 334-4500.
Bats become more active during the warmer months. During this period, the best way to prevent rabies is to avoid exposure. A bat that is active during the day, found in an unusual location such as inside a home, or unable to fly is potentially rabid. Children should also be educated to avoid handling wild animals.
Maryellen Howell, Director of McHenry County Animal Control, urges residents to avoid direct contact with bats and to take proactive steps to bat-proof their homes. “The best way to prevent exposure is to avoid handling wild animals, especially bats,” Howell said. “Since bats can enter through very small gaps, sealing cracks and replacing damaged or loose screens can help keep them out of your home.”
The MCDH offers the following tips to prevent exposure to rabid bats, both inside and outside the home:
- Ensure that doors, windows, and vents have securely framed screens free of holes, chimneys are capped, and gaps around utility lines are sealed.
- Do not touch, feed, or unintentionally attract wild animals with open garbage cans or litter.
- Never adopt wild animals or bring them into your home. Do not try to nurse sick, wild animals back to health. Instead, contact McHenry County Animal Control for assistance.
