Editor’s Note: Initially, MyChesCo pulled county-specific COVID-19 data from the Chester County Health Department’s COVID-19 Dashboard. However, over time, that data became inconsistent and unreliable. Therefore, going forward, except where noted, MyChesCo will be using data from the Pennsylvania National Electronic Disease Surveillance System (PA-NEDSS) as the primary data source for our daily updates. Unfortunately, this means we will no longer publish a breakdown by municipality. We apologize for any inconvenience. All data is provisional and subject to change as new information becomes available.
