Measles is a dangerous and potentially deadly disease, is highly contagious, and can remain in the air for up to two hours after the infectious person has left the area, according to health officials. A brief exposure of 15 minutes can result in measles transmission.
Symptoms can appear up to 21 days after exposure. They can include rash, high fever, cough, runny nose, and red, watery eyes. The rash usually begins on the face and spreads to the trunk. A person is generally contagious for four days before and four days after the onset of a rash.
Anyone who develops symptoms is asked to call a healthcare provider before going to a medical office or emergency department for evaluation. Special arrangements can be made to prevent further exposure to others.
The best way to prevent measles is with vaccination. A two-dose measles, mumps, and rubella (MMR) vaccine provides 97% protection.
