No One Should Get Measles in America | Pittsburgh Post-Gazette
UNITED STATES AND CANADA, JUL 16 – Vaccination rates have dropped below herd immunity thresholds, leading to over 1,300 U.S. cases and more than 1,300 in Alberta, Canada, health officials said.
- The United States has recorded over 1,300 confirmed measles cases and three deaths by mid-2025, marking its worst year since 1992.

- The ongoing outbreak threatens public health progress, emphasizing that vaccination protects individuals and communities, especially those unable to receive vaccines.
