How many measles cases are there in the Valley?

So far in 2026, there are total of 13 confirmed measles cases in Maricopa County, according to MCDPH.

The sixth measles case was confirmed on April 16,and health officials warned that families who attended an Arizona Youth Sports basketball game at Highland Junior High School may have been exposed.

That exposure site came after there were three Queen Creek locations that were identified the week before. In that case, someone who tested positive for measles visited a Costco, a Walmart and an Easter egg hunt at Generation Church Queen Creek before being officially diagnosed.

Arizona has recorded 90 measles cases around the state so far this year.

Health officials urged residents to ensure they are up to date on their measles, mumps and rubella vaccines, adding that 90% of unvaccinated people who are exposed become infected.

Measles symptoms to watch for

Measles symptoms typically appear seven to 12 days after the person has been exposed but can appear up to 21 days post-exposure.

Symptoms of measles include a fever above 101 degrees, red and watery eyes, a cough, runny nose and a rash that is red, raised and blotchy.

It was noted that rash begins after the other listed symptoms and typically appears on the face at the hairline before moving down the body.

Those who develop symptoms are urged to stay home and call a healthcare provider to receive care and testing. It was noted that anyone who believes they’ve been exposed should call ahead and warn the provider about their symptoms and possible exposure.
