Measles Updates
- Measles Cases and Outbreaks | Measles (Rubeola) | CDC ─ As of July 29, a total of 1,333 confirmed measles cases were reported to CDC by 40 jurisdictions. There have been 29 outbreaks reported in 2025, and 87% of confirmed cases (1,156 of 1,333) are outbreak-associated.
- Preparing and Responding to Measles: Checklist for K-12 Schools and Preparing and responding to Measles: Checklist for early care and education centers ─ CDC developed measles preparedness and response checklists tailored for K-12 schools and early care and education centers. These checklists are intended for staff working in these facilities and settings to use in collaboration with their state or local health department. The checklists focus on implementation, specifically how to prepare for measles and what to do in the first 10 minutes after a measles case is suspected.
- Both checklists are also included in the Be Ready for Measles Toolkit.
- Behind the Model: Interactive Measles Outbreak Simulator | CFA: Behind the Model | CDC ─ The Center for Forecasting and Outbreak Analytics (CFA), in collaboration with the CDC Measles Response, developed an interactive simulator for public health decision-makers to explore the potential impact of three key public health interventions—isolation, quarantine, and vaccination—on measles outbreaks. This webpage provides in-depth information about the underlying methodology.
- Since April 2025, CDC has hosted the National Measles Response Call to share updates about measles outbreaks, including epidemiologic data trends, case updates, and new resources. To streamline response-related communication, CDC has sunset this Wednesday 3 p.m. EDT call series. However, measles updates will continue to be shared during the biweekly CDC Response All-STLT Update calls, which require a one-time registration to receive future meeting invitations.
