The CDC is now warning travelers about the potentially deadly virus known as MERS, or Middle East Respiratory Virus.
Notices are going up at 22 airports, including Philadelphia International.
The risk for catching MERS is very low, but the CDC recommends if you are traveling in or near the Arabian Peninsula, pay attention to your health during and after your trip.
They're asking passengers if they experience fever, cough or shortness of breath within 14 days of travel in or near the Arabian Peninsula, visit a doctor and tell that doctor where you have spent time.
Right now, the CDC is not recommending anyone change their travel plans because of MERS.
In most cases when the virus has spread from person to person, it has been in healthcare workers with very close contact to someone infected.
The virus is not believed to be spread through casual contact, meaning if someone coughs and you are a good distance away, chances are you will not get it.
Health officials say this is not a public health emergency, but they are closely monitoring the situation.
