Health officials warn a Hudson Valley Target, a supermarket and other popular local businesses were recently exposed to measles.

On Thursday, Rockland County Executive Ed Day and County Health Commissioner Dr. Patricia Schnabel Ruppert announced there are now 151 confirmed reported cases of measles in the county.

The measles outbreak is affecting residents of Spring Valley, New Square and Monsey, officials say.

"Due to Rockland County's small geographic size, exposure to the measles may occur anywhere in Rockland. People may shop, dine, and run errands around the county before they realize they are ill, but are contagious," Day and Ruppert said in a press release.

As the county continues to deal with the massive outbreak they announced a host of several new locations where residents may have been exposed to the virus.

Since October, there have been at least 211 confirmed cases of measles in New York State. Some 145 cases come from Orange and Rockland counties with 64 cases found in Brooklyn.

Measles is a highly contagious respiratory disease caused by a virus that is spread by direct contact with nasal or throat secretions of infected people. People first develop a fever, then often a cough, runny nose and watery eyes, followed by an appearance of a rash. People are considered infectious four days before to four days after the appearance of the rash.

Symptoms include a fever, rash, cough, conjunctivitis or a runny nose. Symptoms usually appear 10-12 days after exposure but may appear as early as seven days and as late as 21 days after exposure.

In October, it was reported an international traveler with measles visited multiple locations in Rockland and Westchester counties. Among the locations infected with measles was the Costco in Nanuet and Westchester Medical Center.

The Rockland County measles outbreak spread into Orange County in November. Health officials in Orange County later warned that a taxi was exposed to measles. 

Around Thanksgiving, shoppers at the Palisades Mall were potentially exposed to measles.
