IRVINE, Calif. — A bat found in the popular Irvine Regional Park has tested positive for rabies, prompting health officials to issue an urgent advisory to the public.
The bat was discovered on Sunday, May 24, 2026, at 9:30 a.m. in the park, a frequent destination for families, hikers, and outdoor enthusiasts in South County. According to the Orange County Health Care Agency, anyone who may have had physical contact with the bat, or witnessed someone else having contact with it, should call the agency’s Communicable Disease Control Division right away.
“Rabies is a viral disease found in an animal’s saliva,” the health agency explained in its announcement. It spreads primarily through bites from infected animals, though it can also transmit if saliva contacts the eyes, mouth, or an open wound. Bat bites can be particularly tricky because the animals have very small teeth, and the bites may go unnoticed.
Once symptoms appear, rabies is extremely dangerous. As the press release stated: “Once a person begins showing signs and symptoms of rabies, the disease is nearly always fatal.”
That is why prompt action matters. Health officials stress that preventive treatment, which includes thorough wound cleaning and a series of rabies vaccinations, is safe and highly effective when started soon after possible exposure. The treatment stops the virus before it can cause illness.
Pet owners whose dogs or cats may have come into contact with the bat should reach out to their veterinarian immediately. Rabies vaccinations for pets are strongly recommended as a key preventive step.
What to Do If You Were Exposed
Health authorities recommend the following precautions to reduce rabies risk:
- Avoid all contact with wild animals.
- Vaccinate cats and dogs against rabies.
- Keep windows and doors screened at night.
- If a bat enters your home, close off the area and contact animal control.
- Wash any animal bite thoroughly with soap and water, then seek medical care right away.
- Report potential exposures or bites to the proper authorities.
Anyone concerned about possible contact with the bat should call the Orange County Health Care Agency Communicable Disease Control Division at (714) 834-8180, available during business hours or after hours. Animal bites or bats found indoors can be reported to OC Animal Care at (714) 935-6848.
This incident serves as a reminder of the importance of staying vigilant around wildlife, even in well-used recreational areas like Irvine Regional Park. While human rabies cases remain rare in the United States, most recent instances have involved bat strains of the virus.
