Pennsylvania Reports More Than 1,000 Measles Cases Across 39 Counties

Pennsylvania’s measles outbreak has grown to more than 1,000 cases across 39 counties, making it one of the largest outbreaks reported in the United States in decades.

The Pennsylvania Department of Health reported 1,004 cases on Monday, with Lancaster County accounting for 391 confirmed infections.

The state has reported a hospitalization rate of about 20% among 977 patients, more than twice the national rate of 9%. Adults account for 69% of Pennsylvania’s reported cases. Five residents have died, although the fatalities were added to the CDC’s national dashboard only recently following delays in federal reporting.

International health officials are expected to meet in November to assess whether the US has lost its measles-free status. The country is experiencing its worst measles year since 1991.
