Covid-19 cases are on the rise again in Allegheny County, sending the county into “medium” community level as defined by federal guidelines and triggering mandatory masking across Pittsburgh Public Schools.

The levels laid out by the Centers for Disease Control and Prevention — low, medium, and high — take into account the number of new cases per 100,000 people over a week’s time, the number of hospital admissions and the percentage of hospital beds occupied by covid patients.

The move to medium triggered mandatory masking at all Pittsburgh Public Schools buildings. The district lifted its mask mandate last month with the stipulation that it would be reinstated if Allegheny County rose above the low level. Outbreaks at several schools already had prompted closures at several buildings.
