Suffolk officials on Friday said a person infected with the measles visited three locations on the East End.

They say the infected person, who is from overseas, was taking part in a student work program and visited three places on Saturday, April 20. The locations include BNB Bank at 48 East Montauk Highway in Hampton Bays, between 12:15 and 1 p.m.; King Kullen at 52 East Montauk Highway in Hampton Bays, between 2:30 and 5 p.m.; and CVS at 111 South Main St. in Southampton, between 4:45 and 7 p.m.

The virus remains alive in the air and on surfaces for up to two hours.

Health officials say anyone who was at those locations between those times and has not received the measles vaccination is at risk. They add that this case does not appear to be related to other measles cases in New York state.

Mikele Stanfield was working at the Hampton Bays King Kullen when the infected person was there. She says was immediately worried about her 4-year-old daughter and made sure the girl had her shots.

Suffolk County Executive Steve Bellone says the case serves as a reminder for people to take precautions, such as vaccinations, against the highly contagious measles.
