Sept 21 (Reuters) – The Pennsylvania Department of Health reported 792 measles cases on Monday, 25 more than on Friday, ​as the state’s outbreak grew ‌further, remaining at the center of the nation’s worst measles resurgence in decades.

Here are some more details:

• The state health department confirmed 155 hospitalized ‌measles ​patients, up from the ⁠150 reported on September ⁠18.

• Lancaster County has remained the hardest-hit area in the state throughout the outbreak.

• Earlier this month, Pennsylvania reported measles-related ​deaths among unvaccinated residents, a toll that sparked disagreement between Governor Josh ⁠Shapiro and U.S. Health ⁠Secretary Robert F. Kennedy Jr. over ​how many fatalities were directly caused by ​the virus.

• The Centers for Disease Control ‌and Prevention has not yet added Pennsylvania’s 2026 measles deaths to its national count. The agency has said it is ⁠reviewing how it classifies such deaths.

• The US has recorded 3,471 measles cases this year as ⁠of September ‌17, according to CDC data.

• ⁠Measles, a highly contagious viral ​disease, ‌can cause fever, rash and respiratory ​complications, but ⁠is easily preventable with the measles, mumps and rubella vaccine, a routine childhood immunization that is 97% effective after two doses.
