The Boston Public Health Commission is alerting the public of a potential measles exposure at two locations in the city, health officials announced Friday.

The alert comes after the BPHC received a confirmed case of measles.

The commission said anyone who visited the following locations during the specified dates and times could become ill between July 26 and August 10:

Tasty Burger, located near Fenway Park at 1301 Boylston Street on July 19 between 7 p.m. – 11 p.m.

Logan Airport Terminal B on July 20 between 8:30 a.m. – 2:30 p.m.

Tasty Burger said in a statement, "We were notified by the Boston Public Health Commission [Thursday] that there was a possible measles exposure last week at our Boylston Street location. On Thursday, July 19 between 7pm and 11pm, a person diagnosed with measles dined at this location."

The restaurant chain went on to say in the statement that they are working closely with the city's health commission and encourage people to call the BPHC with any questions or concerns.

The Massachusetts Port Authority said in a statement it is cooperating with the Boston Public Health Commission "as they are experts on communicable diseases."

Measles is a highly contagious virus that is spread through the air through coughing and sneezing.

The virus may remain in the environment for up to two hours after the infectious person has left the area, and exposure can occur even without direct contact with an infectious person.

Early symptoms may include a high fever, runny nose, cough and red eyes. A skin rash usually occurs three to five days later and begins as flat, red spots on the face.

The health commission said anyone who experiences any of these symptoms should contact their health care provide by phone immediately.

If a person has had measles in the past or has received two doses of the vaccine, they are unlikely to become ill even if exposed.
