COCA Call: Thurs., 8/14: Clinician update on measles cases and outbreaks in the U.S.

August 11, 2025

This year, record-breaking numbers of measles cases and outbreaks have been reported in the U.S., despite measles being declared eliminated in 2000. While the risk of widespread measles remains low for the general population due to high population-level immunity, measles importations continue to occur. Outbreaks of three or more related cases continue to be reported, especially in communities with low vaccination coverage. Healthcare providers should remain vigilant to rapidly recognize measles and take steps to mitigate its spread.

During this COCA call, presenters will discuss the current epidemiology of measles in the U.S. and address the most common questions from clinicians about preventing, identifying, and testing for measles. Presenters will also summarize MMR vaccination recommendations and considerations.
