They say contact tracing, or calls to people who recently tested positive to try to track the virus, find that many of the new cases were picked up over the holiday weekend, at parties where people weren’t wearing masks, and at the Jersey Shore.
Delaware County officials say about 40% of all new cases are among people under the age of 30.
The Bucks County Health Department's most recent update shows an average of 41 new cases daily. Health officials say they haven’t seen numbers that high since mid-May.
The update also shows that about one-third of new cases were spread within households.
Health Department Director Dr. David Damsker says Bucks County is still seeing the effect of out-of-state travel.
Damsker says hospitalizations in Bucks County remain low — only 23, with three patients on ventilators — and no new deaths have been reported.
