PITTSBURGH -- Officials in Pittsburgh have diagnosed another case of measles and now are urging everyone to take extra precautions.

This is the second case of the measles this past month and the third case so far this year.

Measles is highly contagious and symptoms include a runny nose, watery eyes, a cough and a high fever.

After 4 days a rash starts but infected people can spread measles even before the tell-tale signs of the rash kick in.

"People with measles are infectious four days before the rash starts and four days after --so those were places where that person had been during that time of he/she would have been infectious," said Allegheny County Health Department Dr. Kristen Mertz.

Now doctors advise everyone that if you think you or a family member might have measles to call your doctor and the health department ahead of time before you show up at the doctor's office.
