U.S. Measles Cases Exceed Previous Year's Total by July

Why it matters locally: While the CDC report is national, public health officials in South Dakota would closely monitor these trends to ensure local vaccination efforts are robust and to prepare for any potential local outbreaks, safeguarding the health of the state's 919,318 residents.

The United States has recorded 2,318 measles cases through July of this year, according to a report released Friday by the Centers for Disease Control and Prevention (CDC). This count exceeds the 2,289 cases documented throughout all of last year. The CDC compiled these figures based on reports received up to this point in 2026.
