A raccoon found sick in a Westlake Village backyard has tested positive for rabies, marking Los Angeles County's first confirmed rabid raccoon in more than 50 years. Four people at a worksite were identified as potentially exposed, as was a family dog, and health officials have launched an investigation into how the virus reached a species that almost never carries it in Southern California.
The raccoon appeared sick but was not aggressive toward people when it was found in the yard, according to CBS News. Four people at the worksite were identified as potentially exposed and are undergoing evaluation for rabies post-exposure prophylaxis, while a dog that came into contact with the raccoon, which was up to date on its vaccinations, was placed under home quarantine and is reportedly doing well, per ColoradoBoulevard.net.
A Decades-Long Gap Finally Broken
Los Angeles County had not documented rabies in a raccoon since 1973, and that earlier case carried the skunk variant of the virus, which has not otherwise surfaced in the county's animal population since 1979. The last non-bat animal confirmed with rabies in the county before this case was a Long Beach skunk infected with a bat rabies variant back in 2014, the same outlet notes.
Health officials are now working to determine which rabies variant infected the Westlake Village raccoon, a process that can take several weeks but will help pinpoint the exact source of the infection. Per a news release cited by CBS News, the raccoon was likely infected with rabies from a bat rather than representing a new terrestrial strain circulating locally.
Why a Bat, Not an Eastern-Style Outbreak
That distinction matters because California has no endemic raccoon rabies variant of its own. The Centers for Disease Control and Prevention notes that terrestrial raccoon-variant rabies is established along the Eastern Seaboard, while California instead relies on bats and skunks as its primary wildlife reservoirs, according to a CDC-sourced risk assessment from SaferAbies. The Westlake Village case comes amid rising bat rabies detections in the region, while testing to identify the raccoon's variant remains pending.
That bat surge has been building all year. As of late September, Los Angeles County Public Health officials had confirmed 69 rabid bats in 2026, matching the county's all-time annual record set in 2025, with peak bat season still underway, according to the Los Angeles County Department of Public Health. More than two-thirds of those detections came from the Santa Clarita Valley and were predominantly canyon bats, LAist reports.
A Record Summer for Bat Rabies
The numbers climbed fast over the summer. In August alone, the county confirmed 24 rabid bats, with nearly 32% of all bats submitted by residents for testing coming back positive, according to data from the county health department. LAist adds that roughly one-third of bat encounters in the county happen indoors, where a tiny bite can go unnoticed by a sleeping resident, which is why health officials advise possible-exposure assessment when someone wakes to find a bat in the room or a bat is near a sleeping person, child or pet.
The surge extends well beyond Los Angeles. The CDC reported a 17% nationwide jump in rabies exposure inquiries during July and August compared to the same months in 2025, along with a 33% increase in post-exposure prophylaxis vaccine usage, per WWL-TV. Hoodline has reported similar cases elsewhere in California this year, including a Sutter County child who contacted a rabid bat on September 25.
Why the Vaccinated Dog Avoided a Harsher Fate
The Westlake Village dog's outcome highlights why state pet vaccination law matters. California Health and Safety Code Section 121690 requires every dog owner in the state to vaccinate their dog against rabies once it reaches four months of age, according to FindLaw. Because the exposed dog was current on its shots, California Department of Public Health regulations required a 30-day observation quarantine, compared with up to six months of quarantine or potential euthanasia for unvaccinated pets exposed to rabid wildlife.
Raccoons sharing backyard space with dogs and cats can put pets in contact with infected wildlife. Rabies is fatal in animals once symptoms begin and is transmitted through the bite or scratch of an infected animal, or when its saliva contacts an open wound or a mammal's eyes, nose or mouth, per the CBS News report. In animals, symptoms can include vomiting, respiratory distress, circling, difficulty walking, aggression, paralysis and hydrophobia; in humans, early symptoms include fever, weakness and headache, progressing in advanced cases to tingling sensations, agitation, hallucinations, difficulty swallowing and coma.
Public health officials continue to urge residents to keep a safe distance from wild animals, never touch, handle or feed them, and make sure pets are vaccinated. Genetic variant testing on the Westlake Village raccoon remains underway, and confirming whether the virus is a bat strain will formally establish how the infection crossed into a species the county hasn't seen carry rabies in more than 50 years.
