Health officials are investigating a case of a Florida child with measles who they say was not vaccinated.
Pinellas County Department of Health said Monday that it will be identifying and notifying others who may have been exposed to the virus.
Measles is a virus that is easily spread by air droplets when infected persons breathe, cough, or sneeze. The first symptoms are a high fever that may spike to 105F, cough, runny nose and red, watery eyes. Symptoms are followed by a blotchy rash that spreads from the head to the feet.
It's unclear how the child contracted the virus.
Officials are urging parents to vaccinate their children as the only way to protect against the virus.
