COVID-19 in Western MA

As of July 26, 2020, there were 9,412 confirmed or suspected COVID-19 cases and 917 COVID-19 confirmed or suspected deaths in Western Massachusetts.

Data Source: 

The number of new COVID-19 cases each week in Western Massachusetts has remained fairly steady since the beginning of June, with less than 200 new cases each week.  The graph below shows the number of new COVID-19 cases each week in Western MA as well as milestones for the reopening MA.

As stated in previous newsletters, caution should be exercised when interpreting COVID-19 data. For example, the rate of confirmed COVID-19 cases is dependent upon who is tested and not necessarily reflective of the distribution of COVID-19 in the general population. Testing has been limited thus far.  Because many people who have the disease are asymptomatic and have not been tested, prevalence of people testing positive is unlikely to reflect the prevalence in communities. As testing and contact tracing increase, we will have a better understanding of impacts on communities and populations, and more targeted actions can take place to mitigate spread and support those who are disproportionately impacted.

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 spreadsheets below or visit the county pages.

COVID-19 Vaccine

Based on best available data as of 2/18/21

The state now has a weekly COVID-19 vaccination report.  This weekly report features information on COVID-19 vaccine supply distribution, administration, and other data for Massachusetts.  It is updated each Thursday at 5pm.

Please Note: Some federal facilities in MA receive vaccine from a separate federal distribution system that is not included in this data.


The map below shows COVID-19 vaccine doses shipped to providers in different counties as a percentage of the population.  It is important to note that the providers shown are the initial recipients, and doses may be redistributed to other providers (and other counties).

Data Sources and Notes

  • Sources: 
  • 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). 
  • Race and ethnicity data by county and community is not available at this time.
  • Change in reporting: MDPH changed their reporting of county data on 8/12/20. Previously, county cases were in the Daily COVID-19 Dashboard report and included probable and confirmed cases. Beginning 8/12/20, county data is now reported in the Weekly COVID-19 report and cases only include confirmed cases. Thus, we are not currently able to show new case county-level data and other county-level data over time for periods prior to 8/12/20.
