US measles cases reach 35-year high, threatening elimination status
Axios·US·1 day ago
Measles infections in the United States have reached a 35-year high, exceeding the total case count for the entirety of 2025. The surge represents a significant deviation from recent epidemiological trends, though the specific drivers of this transmission spike remain under investigation.
The United States has confirmed 2,295 measles cases in 2026, surpassing the total for 2025 and marking a 35-year high. Pennsylvania has reported 132 cases, with 27 new cases in the past week, indicating ongoing community transmission. The primary driver is assessed to be low vaccination coverage, threatening the nation's measles elimination status.
