The Massachusetts Department of Public Health issued a public health warning after an infected international traveler potentially exposed individuals to measles while traveling from Hanover, New Hampshire to Logan Airport in Boston, and then onward to Amsterdam on a KLM flight. The incident occurred on June 22, as specified in the alerts.

Recounted by WCVB, the traveler was present on a Dartmouth Coach bus that left Dartmouth College at 11:40 a.m. and arrived at Logan Airport around 2:40 p.m. During the interval stretching from 2:40 p.m. to 8:40 p.m., the individual awaiting their flight was in Terminal E, potentially exposing others in the vicinity. The flight, KLM6016, left from Gate E5 according to the department's warning.

Public Health Commissioner Robbie Goldstein emphasized the high contagion risk associated with measles, especially for unvaccinated persons. "Measles is a highly contagious airborne disease that has seen an increase in cases and outbreaks worldwide," Goldstein said in a statement obtained by GetPocket. He further stressed the importance of vaccination as the most effective protection against measles.

Typical symptoms of measles, which include fever, cough, and a characteristic rash, may manifest up to two weeks following exposure. In attempting to reach those potentially affected by the exposure, officials have faced the challenge of tracking individuals who had shared public transportation with the traveler. The Massachusetts Department of Public Health advises anyone who suspects they may have been exposed to verify their immunization status.

If administered within 72 hours of exposure, the vaccine can still prevent measles, and also offers future protection. Unvaccinated individuals exposed to the virus may face a quarantine period of up to 21 days, a preventive measure to curb further spread of the disease.
