For more than five decades, Los Angeles County had not recorded a confirmed rabid raccoon. That changed in October 2026, when two infected animals were discovered in residential backyards in Westlake Village. Six workers potentially exposed during the separate incidents were receiving follow-up for rabies post-exposure prophylaxis. Testing found that the first raccoon carried a bat-associated rabies variant during a year of record rabid bat detections.

A Sick Raccoon Appears in a California Backyard

In late September 2026, residents of Westlake Village, California, encountered a raccoon behaving unusually in their backyard.

The animal appeared sick but was not aggressive toward people.

At first glance, the situation might not have seemed particularly alarming. Raccoons are common in suburban areas of Southern California, where they search for food around gardens, garbage containers, and residential properties.

However, public health officials examined the animal and discovered that it was infected with rabies.

On October 5, the Los Angeles County Department of Public Health announced the finding.

It was the first confirmed rabid raccoon in the county since 1973.

Authorities identified four people at a nearby worksite who might have been exposed to the infected animal.

County officials said those individuals were receiving recommended follow-up for rabies post-exposure prophylaxis, a preventive treatment given when indicated after possible contact with the virus.

A vaccinated dog had also potentially encountered the raccoon.

The animal was placed under quarantine for observation, and officials reported that it was doing well.

The unusual discovery prompted a countywide warning about contact with wild animals.

Less than three weeks later, another infected raccoon was identified in the same community.

A Second Rabid Raccoon Is Found Nearby

On October 23, 2026, Los Angeles County officials confirmed a second rabies-positive raccoon.

The animal had been discovered in another Westlake Village backyard, near the location of the first case.

Unlike the earlier raccoon, this one reportedly appeared both sick and aggressive.

Authorities identified two people at a worksite who may have been exposed.

Both were receiving recommended follow-up for rabies post-exposure prophylaxis.

According to the county health department, no residents or pets were exposed during the second incident.

The discovery brought the total number of people receiving recommended exposure follow-up after the two raccoon incidents to six.

There was no announcement that any of the six had developed rabies.

The distinction is important.

Post-exposure prophylaxis is given to prevent infection from developing following a possible exposure. Referral for follow-up does not mean that a person has been diagnosed with rabies, and the county did not specify which of the six workers completed treatment.

Nevertheless, two infected raccoons discovered within weeks of each other represented an unusual occurrence in a county where the disease had not been documented in that species for 53 years.

A Bat-Associated Variant in the First Raccoon

The most significant development involved laboratory testing of the first raccoon.

Initial investigators suspected that the animal might have acquired the virus from a bat.

Further testing supported that possibility.

On October 23, the county confirmed that the first raccoon carried a rabies variant typically associated with bats.

That result distinguished the new incident from the county's last confirmed rabid raccoon in 1973.

At that time, a rabies variant associated with skunks was circulating locally.

According to the Department of Public Health, that skunk variant has not been detected in Los Angeles County since 1979.

The county's last confirmed rabid animal other than a bat before the current raccoon discoveries was a skunk found in Long Beach in 2014. That animal also carried a bat-associated variant.

The new raccoon cases therefore raise questions about how rabies is moving between wildlife species.

Rabies variants are generally associated with particular reservoir animals, but transmission can occur between species.

A raccoon can become infected with a bat-associated variant if it has sufficient contact with an infected bat, such as through a bite.

However, the specific route by which the first raccoon became infected has not been publicly established.

Testing of the second raccoon's variant remained pending as of October 25.

Until those results are available, investigators cannot determine whether the two animals carried the same variant.

Even matching variants would not, by itself, establish that one raccoon infected the other.

Los Angeles Has Recorded 77 Rabid Bats in 2026

The raccoon cases occurred during a year of unusually high detected rabies activity among bats.

According to the October 23 health department announcement, Los Angeles County had confirmed 77 rabid bats during 2026, a new local record.

The county has documented an upward trend in rabid bat detections over more than a decade.

Bats are the wildlife species most frequently associated with rabies exposure investigations in Los Angeles County.

The numbers reflect infected bats that were recovered, submitted, and tested. They do not establish what percentage of all bats in the county carry the virus.

Most bats are not rabid, and healthy bats play important ecological roles, including consuming insects.

But the confirmed cases demonstrate that the rabies virus continues circulating in local wildlife.

Peak detections generally occur during late summer, although infected bats can be found throughout the year.

The unusual appearance of two infected raccoons has added another concern to an already record-setting year.

Why Rabies Is So Dangerous

Rabies is a viral infection that attacks the central nervous system.

It primarily spreads through the saliva of infected mammals, most commonly through bites.

Transmission may also occur when infectious saliva contacts broken skin or mucous membranes, including the eyes, nose, or mouth.

The virus travels through the nervous system and can eventually reach the brain.

One of the most dangerous features of rabies is the delay between exposure and the appearance of symptoms.

The incubation period commonly lasts weeks to months, although it can vary.

During that time, an infected person may feel completely healthy.

Early symptoms can resemble ordinary illnesses, including fever, weakness, headache, and discomfort.

As the infection progresses, patients may develop anxiety, agitation, confusion, abnormal behavior, hallucinations, difficulty swallowing, and neurological dysfunction.

Hydrophobia, a severe reaction associated with attempting to swallow liquids, is among the disease's most recognizable symptoms.

Once clinical symptoms appear, rabies is almost always fatal.

However, it is preventable when appropriate treatment is administered promptly after exposure and before symptoms develop.

That is why public health officials responded quickly to the possible exposures in Westlake Village.

Why Six Workers Were Referred for Follow-Up

The preventive treatment administered after a possible rabies exposure is known as post-exposure prophylaxis, or PEP.

According to the Centers for Disease Control and Prevention, treatment for someone who has not previously received rabies vaccination generally includes thorough wound cleaning, human rabies immune globulin, and a series of vaccine doses.

The standard vaccine schedule for previously unvaccinated people consists of doses on days 0, 3, 7, and 14. Some patients require different schedules depending on their medical circumstances.

The treatment is designed to prevent the virus from establishing a fatal infection.

Officials have not publicly detailed the exact manner in which each of the six Westlake Village workers may have encountered the raccoons.

It has not been established that all six were bitten.

Exposure assessments can consider several possibilities, including bites, scratches, and contact involving infectious saliva.

Simply being near an infected animal does not necessarily constitute a rabies exposure.

Nor is rabies ordinarily transmitted through casual contact with an animal's fur or through its urine or feces.

The workers' preventive follow-up represents a precaution following potential exposure, not evidence of a human outbreak.

The First Raccoon Wasn't Aggressive

One of the more important details in the Westlake Village incidents is the difference in the animals' behavior.

The first raccoon appeared sick but was not aggressive.

The second was described as both sick and aggressive.

Rabies can cause several neurological and behavioral changes in wildlife.

An infected animal may become unusually aggressive, appear disoriented, lose coordination, or show little fear of humans.

Other infected animals become unusually quiet, weak, or paralyzed.

Some may approach people or pets in ways that are inconsistent with their normal behavior.

Not every rabid animal behaves aggressively.

Likewise, an aggressive raccoon is not automatically rabid.

Other injuries, illnesses, defensive reactions, or environmental circumstances can influence an animal's behavior.

Laboratory testing, rather than appearance alone, is required to confirm rabies.

The first Westlake Village case illustrates why residents should avoid touching wildlife even when an animal appears relatively calm.

Can Rabies Spread Through an Entire Raccoon Population?

Raccoons are an established rabies reservoir in parts of the eastern United States.

However, the wildlife-rabies situation in California is different.

Bats and skunks account for most detected wildlife cases in the state.

The Los Angeles County raccoon detections are unusual precisely because the animals are not part of a historically documented, locally established raccoon-rabies cycle.

The first animal's bat-associated variant suggests transmission involving another wildlife species rather than the reappearance of the old skunk-associated variant.

But two nearby cases do not establish that rabies has begun spreading sustainably among Los Angeles County raccoons.

Determining whether there is ongoing transmission would require additional surveillance, laboratory results, and investigation of possible contacts among infected animals.

As of October 25, authorities had confirmed two infected raccoons, not a widespread raccoon rabies outbreak.

Officials Warn Residents Not to Feed Wildlife

Following the second case, Los Angeles County Health Officer Dr. Muntu Davis urged residents to avoid touching, handling, or feeding wild animals.

Health officials also emphasized the importance of keeping pets current on rabies vaccinations.

Vaccination is especially important because dogs and cats may encounter wildlife even when their owners do not.

Outdoor pets can come into contact with raccoons, skunks, bats, and other animals near yards, fences, sheds, and crawl spaces.

Even indoor-only pets can occasionally be exposed if a bat enters the home.

The county recommends keeping outdoor garbage containers securely closed, avoiding leaving pet food outside, and sealing openings through which wild animals might enter buildings.

Residents who encounter an animal acting unusually should contact local animal control rather than attempt to capture or handle it.

Anyone bitten or scratched by potentially rabid wildlife should immediately wash the wound thoroughly with soap and water for 15 minutes and seek urgent medical evaluation.

A person should not wait for symptoms to appear before asking whether preventive treatment is necessary.

What Happens Next in Westlake Village?

The Los Angeles County Department of Public Health continues investigating the two raccoon cases.

The most important pending result is the rabies variant identified in the second animal.

If the second raccoon carries the same bat-associated variant as the first, that finding could help investigators assess possible connections between the two cases.

If it carries a different variant, the result could point toward separate introductions of rabies.

Either outcome would require additional interpretation.

Public health officials are also monitoring rabies activity in bats and other wildlife.

The available announcements have not established that additional raccoons have tested positive or that any of the six potentially exposed people have developed the disease.

The confirmed situation is limited but significant: two infected raccoons were found in the same general neighborhood, six workers received recommended exposure follow-up, and one vaccinated dog was quarantined following possible exposure.

A Disease That Returned After More Than Half a Century

For 53 years, Los Angeles County had no confirmed rabid raccoon.

Then two appeared within weeks of each other in suburban backyards.

The animals showed different symptoms. One was not aggressive, while the other was.

Both tested positive for a virus that is almost always fatal once symptoms develop.

Investigators also discovered that the first animal carried a rabies variant usually associated with bats, during a year when the county recorded an unprecedented 77 rabid bats.

The cases have not produced a confirmed human rabies infection, and the available evidence does not demonstrate a widespread outbreak.

Nevertheless, they show how a virus circulating in one wildlife species can occasionally appear in another.

The most unsettling detail is that the first infected raccoon was not aggressive. It was simply a sick animal discovered in an ordinary backyard — and it carried a virus that had not been confirmed in a Los Angeles County raccoon for more than five decades.
