Another Hudson Valley county has multiple confirmed cases of measles.

On Thursday, the Sullivan County Public Health Department was notified of two positive cases of measles in Sullivan County residents. The two people were considered to have been contagious from March 4 to March 12.

During the time period, they were mostly in Sullivan County but did spend time in and travel to Brooklyn where there is an ongoing measles outbreak, officials say.

Both Sullivan County and the NYC Health Department, in conjunction with the NYS Department of Health, are working to contact those suspected of having been exposed during this contagious period. There are no known exposures to Sullivan County residents at this time.

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.
