Measles in Arizona: Signs, Symptoms and Prevention

PHOENIX (June 17, 2025) – The Maricopa County Department of Public Health recently reported a measles exposure at Phoenix Sky Harbor Airport, bringing renewed attention to the importance of prevention when it comes to this highly contagious disease.

Measles is spread through the air when a person coughs or sneezes, and can linger in the air for up to two hours after an infected person leaves a room. The best way to protect yourself is by getting the measles, mumps and rubella (MMR) vaccine.

“When it comes to viral diseases like measles, it is important that we all do our part to protect ourselves and those around us by staying up to date on the MMR vaccine,” said Dr. Omar Gonzalez, epidemiologist for Dignity Health in Arizona. “In fact, there is a 90% chance a person will become infected with measles if they are exposed and unprotected. We all have to do our part to keep our community healthy.”

Those most at risk of developing serious complications from measles include young children, pregnant women and the immunocompromised.

Symptoms typically appear seven to 21 days after exposure and include cough, runny nose, fever, rash and watery eyes that are red and sometimes itchy.

Anyone who develops these symptoms or believes they may have been exposed to measles, should call their provider for instructions before visiting a clinic. Calling ahead helps prevent additional exposures.

If you have a life-threatening emergency - such as chest pain, trouble breathing, or stroke symptoms - do not delay care. Go to the ER or call 911 immediately.

More information about measles and the MMR vaccine can be found on the CDC website.
