Measles Cases Surge in Wyoming, Utah, and Michigan

Measles cases in the United States have surged to near 30-year highs, with Wyoming confirming its first case since 2010 in an unvaccinated child from Natrona County whose source of infection remains unknown. Exposures occurred at Banner Wyoming Medical Center's emergency department, and health officials urge those exposed to monitor for symptoms and avoid crowded places for 21 days. Utah has reported nine cases, all in unvaccinated individuals, with at least two hospitalizations and two cases involving pregnant women; local health authorities are monitoring exposures and emphasizing vaccination. Michigan has also reported new cases as part of the broader national rise. The CDC reports most U.S. measles cases are in unvaccinated people and linked to outbreaks, often involving travel or healthcare settings. Health officials nationwide highlight the importance of the MMR vaccine, which is about 97% effective after two doses, especially for vulnerable populations.
