58 Measles Cases Confirmed in the U.S.

The U.S. Centers for Disease Control and Prevention (CDC) and the World Health Organization say the increased number of measles outbreaks is a global threat in 2024.

As of March 14, 2024, a total of 58 measles cases were reported by 17 U.S. jurisdictions: Arizona, California, Florida, Georgia, Illinois, Indiana, Louisiana, Maryland, Michigan, Minnesota, Missouri, New Jersey, New York City, Ohio, Pennsylvania, Virginia, and Washington.

In 2023, a total of 58 measles cases were reported by 20 U.S. jurisdictions.

In 2024, the Chicago Department of Public Health (CDPH) confirmed twelve measles cases, including an active outbreak at a local shelter in Pilsen. CDPH is coordinating a comprehensive, city-wide response to the first measles cases in Chicago in five years.

CDPH is encouraging all new arrivals to Chicago and every Chicagoan to get the measles-mumps-rubella (MMR) vaccine if they haven't already done so.

The vast majority of Chicagoans are vaccinated against measles and therefore not at high risk," said CDPH Commissioner Olusimbo 'Simbo' Ige, MD, MPH, in a press release on March 12, 2024.

"But those who are unvaccinated need to take precautions. If they're exposed, quarantine immediately and connect with their healthcare provider. Above all else, get vaccinated so you, too, can be protected from this virus."

In the U.S., MMR vaccines are available at most community pharmacies as of March 18, 2024.
