More than two dozen Central Park raccoons have died in an ongoing viral outbreak that causes “zombie” behavior in the critters, authorities determined.

Of 26 raccoons found dead or sick inside the park since June 24, two tested positive for the canine distemper virus, which doesn’t affect humans but can spread to unvaccinated dogs, officials with the city Health and Parks departments revealed on Saturday. The other 24 are believed to be infected by distemper because they were found clustered in such a short time and area.

The latest raccoon was found at East 106th Street and East Drive on Saturday morning.

Parks staff also have witnessed distemper symptoms in living raccoons. “They looked like they were circulating, wandering, having spasms,” said Dr. Sally Slavinski, an assistant director at the Health Department. “Some of the raccoons had some sort of nasal discharge.”

Raccoons with distemper act strange — appearing tame or confused before losing their coordination, becoming unconscious and sometimes dying. They can also get aggressive.

None of the raccoons have tested positive for rabies so far. Once authorities ruled out that deadly virus, they sent samples from two dead raccoons to a state lab. The city found out Friday that they were dealing with distemper.

While officials stressed humans can’t contract the disease, dog owners in Central Park were alarmed Saturday when told of the outbreak.

“Now I’m freaked out. Holy moly!” said Upper East Sider Bob Cucurullo, 40, with his beagle terrier Charlie. “He sees a raccoon once a week, and he goes nuts after it. Now I’ll have to be careful where I let him go.”

Most dogs are vaccinated for distemper. The city mandates all dogs and cats get the rabies vaccine, but distemper immunization is only required if pups are going to a boarding or grooming facility.

Distemper spreads when animals make contact with infected saliva, urine, feces or respiratory discharge. Central Park skunks can get the virus. So can coyotes, foxes, ferrets and exotic large cats, like the snow leopards at the Central Park Zoo.
