Measles 2026: 910 confirmed cases in 23 states since January 1; South Carolina and Florida outbreaks growing
As of February 12, CDC reported 910 confirmed measles cases in 23 states in 2026. Six new outbreaks started in 2026. Since the current national measles surge began in 2025, 276 people have been hospitalized due to measles. According to CIDRAP News, the upstate South Carolina outbreak, now at more than 950 confirmed cases since October 2025, is the largest single outbreak of measles in the United States in more than 30 years. CIDRAP News also reports a growing outbreak at Ave Maria University in south central Florida is up to at least 54 cases, although case counts vary by reporting source.
CDC only requires reporting of laboratory-confirmed measles cases. Cases without laboratory testing for confirmation are not included in these numbers. Actual numbers of cases are, therefore, higher than confirmed case counts.
