County health officials are warning of another measles outbreak - the second this month-- after a Spring Valley man got sick in Israel and traveled back.

County Health Commissioner Dr. Patricia Schnabel Ruppert estimates more than a half-dozen people may now have the measles, exposed after the infected traveler visited a Costco in Nanuet, a spa in New City, several Jewish congregations in Monsey and a handful of other places in Rockland and New Jersey, as well as the Westchester Medical Center emergency room.  This occurred between Oct. 4 and Oct. 11.

List of visited locations: 

By law, children who enter public school must be vaccinated.

People over age 60 are also protected, along with anyone who has had both doses of the measles vaccine.

Symptoms of the measles include fever, runny nose, red eyes that are sensitive to light, coughing and a red rash. The virus remains alive in the air and on surfaces for up to two hours. The illness usually appears 10 to 12 days after exposure, but can sometimes take up to three weeks to develop.

People considered to be high risk if they were exposed are women who are pregnant, children under 6 months of age, people who have problems with their immune systems and people who have not been vaccinated against the measles.

Health officials say to call your health provider right away if you've been to any of those spots during the days and times listed.

Rockland County health officials say the infected person is now being treated and is isolated.
