The Los Angeles County Department of Public Health is investigating a rabies-positive raccoon found in the Westlake Village area of Los Angeles County. The raccoon was encountered in a backyard and reportedly appeared sick but not aggressive towards people. One dog that was up to date on rabies vaccine may have been exposed to the raccoon, is under quarantine and is currently doing well. Four people at a worksite may have been exposed to the raccoon and are receiving recommended follow-up for rabies post-exposure prophylaxis.

The last known confirmed rabid raccoon in Los Angeles County was detected in 1973, when the skunk variant (strain) of rabies was still present in the County. That strain has not been detected in LA County since 1979. The last non-bat animal confirmed to have rabies in Los Angeles County was a skunk infected with the bat variant of rabies in Long Beach in 2014.

The rabies variant this raccoon was infected with has not yet been determined. Variant typing is important for understanding the likely source of the infection. Based on current knowledge of rabies occurrence in Los Angeles County, it is likely this raccoon was infected with rabies from a bat. However, Public Health is awaiting subsequent variant testing, which can take several weeks.

Rabies remains a public health concern worldwide. Although it is preventable, it causes tens of thousands of human deaths globally each year, with most human cases linked to exposure to dogs in countries where the dog strain of rabies is still present. While the dog strain of rabies was eradicated in the United States through routine vaccination of pets, other strains of rabies continue to circulate in wildlife, including bats. All strains can infect any mammal and cause disease.

“The detection of rabies in a raccoon is an important reminder to never touch, handle, or feed any wild animals, even when they appear healthy,” said Muntu Davis, MD, MPH, Los Angeles County Health Officer. “Always keep a safe distance from wildlife and contact your local animal control if you encounter an animal that appears sick, injured, or is behaving unusually. It is also critical to ensure your pets are up to date on rabies vaccination so they are protected before any potential exposure. Keeping your pets vaccinated is one of the most important steps you can take to protect your entire family.”

Rabies in Los Angeles County

Historically, rabies exposures in Los Angeles County have been associated with contact with bats. Rabid bat detections can vary year-to-year, but Los Angeles County has seen a steady upward trend for more than a decade. Peak season typically occurs in late summer. So far this year, there has been a record-breaking 70 rabid bats confirmed in Los Angeles County.

Public Health Reminds Everyone in Los Angeles County: Never Touch a Wild Animal & Vaccinate Your Pets

The two most important rules are simple:

• Never touch a bat or any wild animal, and never allow pets to interact with them. Even small or unnoticed bites can transmit rabies.
• Vaccinate your pets: Rabies is 100% fatal in animals once symptoms begin, but completely preventable through vaccination. This includes vaccinating indoor-only cats and older pets, and ensuring your pets stay current on their rabies vaccine. Protecting your pets from rabies is one of the best ways to protect your whole family.

Other safety practices include:

• If you are bitten by a wild mammal (raccoon, skunk, opossum, coyote, etc.), seek medical advice immediately and report to Public Health: Rabies is preventable with post-exposure prophylaxis (PEP), a series of timely vaccines.
• If your pet is bitten by a wild mammal (raccoon, skunk, opossum, coyote, etc.), seek veterinary care immediately and report to your local animal control and Public Health. Your pet will need rabies vaccine and temporarily quarantine at home for observation.
• Know signs of illness in bats and other wildlife: Wildlife that are ill may act more aggressive, may try to interact more with humans and pets, act sick or uncoordinated. Bats are nocturnal. Bats that are active during the day, on the ground, or unable to fly may be sick. Contact your local animal control immediately for collection and testing.
• Report bats and sick wildlife right away: If you notice sick wildlife, do not approach it, nor let your pet approach it. Call your local animal control. If you find a bat in or outside your home, especially near a sleeping person, child, or pet, carefully cover it with a box or container if it is safe to do so and call animal control immediately for collection and testing. Do not release it.
• Avoid attracting wildlife or free-roaming animals: Do not leave pet food outdoors. Do not feed or touch free-roaming animals.
• Maintain your property: Keep trash in containers with tightly fitting lids. Close off crawl spaces and seal openings where animals can enter, hide, or find food. Keep your yard free of debris and trim overgrown plants and bushes.
