Summary The total number of COVID-19 tests administered and the 7-day average percent positive rate in each Maryland jurisdiction.

Description Testing volume data represent the total number of PCR COVID-19 tests electronically reported for Maryland residents; this count does not include test results submitted by labs and other clinical facilities through non-electronic means. The 7-day percent positive rate is a rolling average of each day’s posi"tivity percentage. The percentage is calculated using the total number of tests electronically reported to MDH (by date of report) and the number of positive tests electronically reported to MDH (by date of report). Electronic lab reports from NEDDSS. Upon reaching a limit to the Socrata Platform, we decided to break the data into two parts (now 3 parts). We now have "MD COVID-19 - Total Testing Volume by County", "MD COVID-19 - Total Testing Volume by County 2020 Archive", "MD COVID-19 - Total Testing Volume by County 2021 Archive", and "MD COVID-19 - Total Testing Volume by County 2022 Archive".
