Baystate Medical Center announced Saturday afternoon that they are treating a patient that has a confirmed case of measles.
Hospital officials said anyone who was in proximity of the patient on April 2 or 3 may be at risk for developing the disease.
Baystate said the group of people potentially exposed at the hospital was around 300 individuals.
The hospital is now directly contacting people who they believe are at an elevated risk.
People with the potential for exposure are being asked to be watchful for symptoms of measles and should call their healthcare provider if they develop symptoms.
The hospital said those symptoms would occur 10 days to two weeks after exposure and may resemble a cold, but a rash occurs on the skin two to four days after the initial symptoms develop.
Baystate said people who were born before 1957, have had measles in the past or who have been vaccinated against measles per Centers for Disease Control and Prevention recommendations are considered immune.
