Note about comparisons to previous two-week period: Symbols indicate change when compared to prior two-week period.  For new cases, incidence per 100,000, and total tests: Higher (upward arrow) means the number in the current two-week period is higher than the prior period. Lower (downward arrow) means the number in the current two-week period is lower than prior two-week period. No change (equal sign) means the number in the current two-week period is the same as the prior period. For percent positivity: less than 0.10% difference in the percent positivity is considered No change (equal sign).

Community-Level COVID-19 Data Over Time

On November 6, 2020, the Baker-Polito Administration released updated metrics for communities that adjust for a municipality's population size.  The new metrics incorporate cases per 100,000 residents and the test positivity rate when determining a color designation.  More details about the color designations can be found in the table below.  To see community designations, please download the incidence rate spreadsheet below.

Data Sources

  • MDPH Weekly COVID-19 Public Health Report. Current two week data is from most recent Public Health Report. Prior two week data is from prior week’s Public Health Report. Please note that there is an overlap in periods as MDPH reports weekly on rolling two week reporting periods, which they use for their comparisons. We report data in this way to be consistent with MDPH reporting.
