Rabid raccoons are back in Manhattan. Vaccinate your pets, health officials say

New York City health officials want you to keep your distance from creatures like this raccoon and other wild animals that can carry rabies.

(CNN)Years after an outbreak was stamped out, rabies has returned to the raccoons of New York City's most densely populated borough.

Four raccoons with rabies have been found since the start of the year in the upper portion of Manhattan, the first seen on the island since 2011, the city health department said Friday.
Officials are using the discoveries to remind city residents to vaccinate their pets against the deadly disease.
"The city has done a great job keeping our wildlife free from rabies, but sometimes Mother Nature has other ideas," state Sen. Robert Jackson said in a news release.
