US health authorities reported 178 new measles cases this week, bringing the total to 4,588 cases nationwide, more than double the number from 2025.
The Centers for Disease Control and Prevention (CDC) reported 4,588 cases of measles across the United States as of Friday, more than double the number recorded in 2025. This includes 1,338 cases in Pennsylvania, with large outbreaks also reported in South Carolina and Utah, each exceeding 500 cases. The CDC confirmed the new cases as part of at least 43 outbreaks across the country.
Health Secretary Robert F Kennedy Jr has faced criticism for his handling of vaccine-related policies, including changes to vaccine injury reporting systems and the removal of CDC statements about vaccines and autism. The CDC has also been accused of lacking transparency in reporting measles deaths, with one death location undisclosed. Kennedy reportedly asked senior CDC officials in September to remove a measles death from the official tally after he questioned whether the disease contributed to the death, according to Reuters.
