The Philadelphia Department of Public Health is reporting a possible measles exposure at the main campus of Children's Hospital of Philadelphia on Sept. 11.

The Philadelphia Department of Public Health is also encouraging people to check their vaccination status and watch for symptoms. Measles symptoms include fever, runny nose, cough and red, watery eyes, followed by a rash, officials said. "We encourage people to get vaccinated not only to protect themselves, but to protect those who cannot get vaccinated.
This is why it is imperative that everyone who is eligible gets up to date on the vaccines they need so we can protect our most vulnerable," Health Commissioner Dr. Palak Raval-Nelson said. Children's Hospital of Philadelphia declined to comment or share more information.
What is measles? Measles is caused by a virus and is transmitted through the air from coughing and sneezing, according to the Centers for Disease Control and Prevention . It spreads very easily because it can linger in the air for hours.
Two doses of the measles, mumps and rubella (MMR) vaccine are the best protection against the virus. Measles protection is also part of the MMRV vaccine, which includes varicella (chickenpox). The vaccine is safe and is extremely effective at preventing measles, and adults can be vaccinated as needed, Philadelphia health officials said.
If you are not immune to the virus and develop symptoms through Oct. 2, you should contact your doctor right away, according to the health department. You should let your doctor know you may have been exposed to measles if that's the case, and contact your local health department as well.
