European visitor enjoyed Boston area; now health officials sound warning because person had measles

State public-health officials have released the itinerary of a European visitor to the Boston area earlier this month and say anybody who might have been in the same area at the same time as this person might want to check with their health-care provider because that person came down with measles.

The locations include the Cambridgeside Galleria on the afternoon of May 1, the 1 bus that morning and the Green Line later that afternoon and the Star Market at the Pru and the Nespresso on Newbury Street on the afternoon of May 4.

Officials say this is the state's first measles case this year.

Those who think they may have been exposed to measles should immediately confirm that they have had two doses of MMR vaccine or have laboratory evidence of immunity to measles. Those without immunity to measles should contact their healthcare provider to get a dose of MMR vaccine as soon as possible. People born in the US before 1957 are unlikely to be susceptible to measles, but may consider getting a dose of vaccine. Young infants, pregnant women, and those with severe immunocompromising health conditions who may have been exposed are at particular risk and should contact their healthcare providers as soon as possible. A medicine called immune globulin may be given to help modify measles. Those who are unable to get vaccinated and have no other proof of immunity may need to refrain from all public activities for up to 21 days after the exposure to avoid spreading the infection.
