State public health officials confirmed Tuesday that a child has been diagnosed with measles, the second case of the contagious disease diagnosed recently in Greater Boston.
State officials did not share details of where the child is currently located. The patient’s exact age and hometown were not released.
“Over the weekend, DPH confirmed a second case of measles in Greater Boston and reminds you that getting vaccinated is your best protection against the disease,” the Department of Public Health said in a press release.
The child visited several locations in Quincy and Weymouth earlier this month.
Public health officials urged anyone who did not know their measles immunization status to get vaccinated with at least one dose of the measles, mumps, and rubella (MMR) vaccine.
Measles vaccine given within 72 hours of exposure may prevent the disease, officials said in the statement.
Vaccination beyond this window will provide protection from subsequent exposures, according to the state health department.
The person first diagnosed with measles in Massachusetts was not a child, a department spokesman said.
The Massachusetts cases are part of an outbreak both nationally and internationally that public health authorities have linked to people refusing to be vaccinated against the highly contagious disease.
The health department provided this timeline for the child who was diagnosed:

Between Jan. 1 and May 24 this year, 940 cases of measles have been confirmed in 26 states, according to the Centers for Disease Control and Prevention.
That number represents the highest number of cases reported in the country since 1994, according to the CDC. According to that agency, the majority of people who get measles are unvaccinated.
Early symptoms of measles occur 10 days to two weeks after exposure, state officials said.
Such symptoms may resemble a cold, with a fever, cough, runny nose, and red eyes. A rash occurs on the skin two to four days after the initial symptoms develop, usually first appearing on the head and then moving downward, officials said.
According to the state, people with measles may be contagious up to four days before the rash appears and for four days after the day the rash appears.
