Pennsylvania surpasses 900 measles cases

Pennsylvania on Monday surpassed 900 measles cases , after adding more than 100 additional cases in the past week.

The Pennsylvania Department of Health updated its measles dashboard Monday, putting the total number of cases in the state at 903, after 115 new infections were recorded in the past week.

Pennsylvania is currently reporting the highest total number of measles cases in the U.S., according to the Centers for Disease Control and Prevention (CDC), followed by South Carolina and Utah.

The state has become embroiled in a feud with the Trump administration in recent weeks after it reported the first measles-associated deaths of 2026. When local officials reported being unaware of any measles deaths, federal health leaders like Health and Human Services Secretary Robert F. Kennedy Jr. openly questioned whether the deaths had even occurred .

The deaths were later confirmed to have been caused by measles. While Pennsylvania currently reports four measles-associated deaths, the CDC’s total tally only lists one death as of Monday.

According to Pennsylvania’s health department, less than 1 percent of measles cases occurred in people who were fully vaccinated against the virus; 176 have been hospitalized; and about 31 percent of cases occurred in people under 18.

This year has been one of the worst for measles in the U.S. in more than 30 years, with the highest number of annual cases reported since 1992.

The U.S. eliminated measles in 2000, but that status is set to be reevaluated in an upcoming November meeting with the Pan American Health Organization. Canada lost its elimination status last year.
