Five children in Orange County have measles, with two of those children attending local schools.
"Typically we don't see measles cases often, but currently there are five confirmed cases in Orange County," said Orange County Health Commissioner Dr. Irina Gelman.
According to Gelman, the onus rests on her department to step in and make sure it does not spread.
"The children that are exhibiting symptoms of the measles, as well as anyone who may be unimmunized or underimmunized, will be contacted by our nursing staff here, and they would be excluded from school," Gelman said.
The measles may start off with a cough and runny nose, but symptoms get more intense.
"So you should worry about measles if you have a high fever, you feel sick, you have a rash, and you know you haven't been vaccinated," said Greater Hudson Valley Health System Epidemiologist Dr. Marina Keller.
Spectrum News also asked if the community should be worried with these cases.
"Well, there's always concern with a highly communicable disease. Definitely this is the opportunity to make sure you are up to date on your vaccinations," Gelman said.
If you think you or someone in your family may have the measles, it is important to call your doctor or medical office ahead of time Gelman says.
"You don't want to expose other people in the waiting room to this highly contagious infection. So you want to call ahead, and when you get there, you put on a mask to protect the other people in the doctor's office or the emergency room," Keller said.
The state Department of Health says measles can be passed on four days before, and up to four days after the rash appears.
Rockland County is reporting 95 confirmed cases of measles as of Friday. That's up from 90 confirmed cases of the contageous disease a week ago.
