Chester County COVID-19 Message

IMPORTANT NOTES ABOUT COVID-19 DATA

 5/21/20  There are multiple dates associated with a test record – everything from the date the test was collected to the date the test was reported.  Chester County has been reporting COVID-19 data based on test report date – when a test result is reported by the laboratory.  Effective May 21, we are transitioning to use the date the test was collected.  This date is closer to symptom onset date and removes the variability of laboratory processing capacity and reporting capability.  This move will allow us to more accurately reflect the current conditions of COVID-19 in our county, further supporting our readiness to relax restrictions.

05/20/2020: Chester County and Delaware County data is reliant on daily data received by the Pennsylvania Department of Health. The State’s data is not available as of noon today, May 20, 2020. The data maps will be updated as soon as the data is received. Thank you for your patience.
05/5/2020: The unusual jump in the number of Chester County COVID-19 deaths reported by the PA Department of Health on 5/5/20 reflects a reconciliation in systems between numbers previously reported by hospitals and coroners, and numbers provided to health departments. This reconciliation includes a retrospective review of COVID-19 deaths between both original reporting systems.
04/27/2020: Many positive case records without a valid address currently posted as “Location Pending Investigation” have been cleaned up. While this cleanup will not change the overall county totals, it will change the totals within municipalities.
04/23/2020: The PA Department of Health has removed the deaths published yesterday from their reconciliation to allow more time for further review by the state. We apologize for this confusion this is causing.
04/22/2020: The unusual jump in the number of Chester County COVID-19 deaths reported by the PA Department of Health today reflects a reconciliation in systems between numbers previously reported by hospitals and coroners, and numbers provided to health departments. This reconciliation includes a retrospective review of COVID-19 deaths between both original reporting systems, and this process will be used from this point on to help all reporting to be more consistent and accurate.
