ALLEGHENY COUNTY, Pa. — (WPXI) – With rising COVID-19 cases, especially among children younger than 12, Allegheny County officials said Wednesday they’re worried about the numbers and that events like football games could be canceled. “We continue to see an increase in cases among children, especially among children who are not old enough to get vaccinated,” said Allegheny County Health Department director Dr. Debra Bogen. At a news conference Wednesday, Bogen said there were 157 cases in children younger than 12 in July. That number skyrocketed to 773 cases in August. She said the county reported 450 new cases of COVID-19 Wednesday, with more than half of them classified as probable cases. She said cases are being tracked back to large and small gatherings, weddings, parties, concerts and youth football games.
