SLIDESHOW: Count and Rate of Confirmed COVID-19 Cases and Tests Performed in MA by City/Town, January 1, 2020 – November 11, 2020:

Data are current as of 8 am on 11/11/2020; For populations <50,000, <5 cases are reported as such or suppressed for confidentiality purposes.

  • Number of new cases occurring over the current two-week period (10/25/2020 – 11/07/2020) compared to the previous two-week period (10/18/2020 – 10/31/2020).
  • Higher=number of new cases in the current two-week period higher than the number of new cases during the last two-week period. Lower=number of new cases in the current two-week period lower than number of new cases during the last two-week period.
  • No change=number of new cases in current two-week period is equal to the number of new cases
  • during the last two-week period.
  • Change in percent positivity compared to the previous week’s (11/5/2020) report.
  • No Change= <0.10% difference in the percent positivity. Municipalities marked with an asterisk (*) have either a long-term care facility, institution of higher education and or correction facility with:
    • More than 10 confirmed cases in the last 14 days
    • These cases make up more than 30% of the total cases for that municipality in the last 14 days.
  • DPH calculates rates per 100,000 population using denominators estimated by the University of Massachusetts Donahue Institute using a modified Hamilton-Perry model (Strate S, et al. Small Area Population Estimates for 2011 through 2020, report, Oct 2016.)
  • As of 11/5/2020, the Massachusetts Department of Public Health is using the 2019 population estimates, the most current available data.
  • Please note: Data for these tables are based on information available in the DPH surveillance database at a single point in time. Case counts for specific cities and towns change throughout the day as data cleaning occurs (removal of duplicate reports within the system) and new demographic information (assigning cases to their city or town of residence) is obtained.

Department of Public Health Revises COVID-19 Daily Dashboard

BOSTON (Mass.gov) – Beginning November 2, the Massachusetts Department of Public Health (DPH) will post a revised COVID-19 daily dashboard. This revised dashboard will continue to provide critical information for the public’s understanding of the current and cumulative impact of the pandemic in Massachusetts, reflecting the metrics that are most useful to track on a daily basis.

The Commonwealth already produces one of the most comprehensive public data reports on COVID-19 in the nation and includes detailed municipal-level, college and university, contact tracing, long-term care facilities, and, most recently, cluster data.

The revised dashboard will help the public more easily access the Commonwealth’s growing amount of COVID-19 information as the Department prepares to launch an interactive digital dashboard early next year.

A key new data point presented in the dashboard is “Case Growth by Age Group,” which will help contextualize the impact of COVID on different age ranges over time. The Commonwealth is currently seeing a larger proportion of cases in younger people compared to earlier in the pandemic.

The dashboard will now include the average turnaround time for COVID-19 test results to be reported to the Department, so contact tracing can begin. The dashboard will also now report the impact of college and university-testing to greater clarify how this testing impacts the Commonwealth’s overall positivity rate and case numbers.

The updated dashboard provides a more granular look into the daily positivity rate.  Since August, the Commonwealth’s universities have been conducting at least 25,000 daily tests of students, faculty, and staff. While this testing has helped to control the spread of COVID on college campuses, it has also impacted the overall positivity rate. The dashboard will include three positivity rates: the overall state positivity rate, the positivity rate on college campuses, and the statewide positivity rate excluding on-campus testing.

Many existing data points, including testing, deaths, and hospitalization rates, have been reorganized to report on current numbers, trends over the past six weeks, and trends going back to March.

Going forward, the daily dashboard will be posted at 5 p.m. The daily dashboard, Weekly Public Health Report, raw data feeds, and other COVID-19 data and information can be found at www.mass.gov/info-details/covid-19-response-reporting.
