Dig deeper:

Measles spreads through the air when a person coughs, sneezes or breathes, and the virus can stay infectious in the air and on surfaces for up to two hours. Early signs of measles include fever, cough, runny nose and red, watery eyes, with a rash following a few days later. Symptoms can start 7 to 21 days after exposure.

"My deepest sympathies are with the loved ones who are facing this unimaginable loss." Secretary of Health Dr. Debra Bogen said. "Because measles was largely eliminated in the Commonwealth for more than three decades, people are not familiar with this disease and don't fully understand the potential severity of the illness."

Stronger call for vaccination from state officials

What they're saying:

The MMR vaccine is given in two doses and boosts a person’s immune system, providing 97% lifetime protection against measles, according to the Pennsylvania Department of Health.

"As a physician, I want to make sure that people understand that the MMR vaccine is safe and provides the best protection we have against measles," Dr. Bogen said.z

What's next:

The Pennsylvania Department of Health will not release more details about the individuals or their families, citing privacy concerns as a core responsibility. The department continues to advise Pennsylvanians to check their vaccination status and contact a healthcare provider if they have symptoms or may have been exposed.
