Blair, Jefferson, Elk, and Cameron Counties are currently in the “moderate” level of transmission.

For counties with a substantial or high level of transmission, the CDC recommends that people wear masks indoors, even if they are fully vaccinated. Vaccine data shows 63.3% of Pennsylvanians age 18 and older are fully vaccinated in the commonwealth, according to the Pennsylvania Department of Health.

The Department of Health also reports 1,731 new cases of COVID-19 since Aug. 4. In Pennsylvania, 642 individuals are hospitalized with COVID-19 and 141 patients are in the intensive care unit.
