Boston health officials are reporting five new cases of measles, including a 40-year-old man who worked at Boston's South Station while he was contagious.
Officials said Tuesday the other patients ranged in age from 16 months to 65 years. One lives in Boston, and the others were treated at Boston health facilities while visiting, but no other connections exist between the patients.
"There may eventually be a link that's been identified, but at this time there is no link that is obviously connecting people," said Julia Gunn, director of Communicable Disease Control for the Boston Public Health Commission.
Health officials say they're visiting any places the five may have visited and are urging residents to check their vaccination history to make sure they are protected.
There have been 10 confirmed measles cases in Massachusetts this year.
The Massachusetts Department of Public Health sent an advisory about the latest cases to clinicians and health care professionals across the state.
