What to Know Two European tourists with measles visited three Jehovah's Witness facilities last week

One was in Brooklyn and the other two were in Orange and Putnam counties

It was at least the fourth time this year European travelers with measles visited the tri-state area

Two European tourists with measles potentially exposed others at three Jehovah's Witness facilities in the greater New York City area, health officials said Saturday night.

The two tourists visited the Kingdom Hall of Jehovah’s Witnesses on New Jersey Avenue in Brooklyn between 10 a.m. and 2 p.m. on April 15.

They also visited Watchtower World Headquarters on Kings Drive in Tuxedo Park between 11 a.m. and 4:30 p.m. on April 16 and the Watchtower Educational Center on Watchtower Drive in Patterson between 10 a.m. and 4 p.m. on April 17.

Officials urged anyone who was exposed and is suffering symptoms to contact a health care provider before seeking treatment in order to minimize exposure.

Symptoms include a fever, rash, cough, conjunctivitis or runny nose. Symptoms usually appear 10 to 12 days after exposure but may appear as early as 7 days and as late as 21 days after exposure, the state said.

This most recent incident marks the fourth month in a row that European tourists with confirmed cases of measles have traveled through the tri-state area. Officials previously warned of one incident in Manhattan and two at Newark Liberty International Airport.
