These are days with a reporting anomaly. Read more here.

About this data Sources: State and local health agencies (cases, deaths); U.S. Department of Health and Human Services (tests, hospitalizations). The seven-day average is the average of a day and the previous six days of data. Currently hospitalized is the most recent number of patients with Covid-19 reported by hospitals in the state for the four days prior. Dips and spikes could be due to inconsistent reporting by hospitals. Hospitalization numbers early in the pandemic are undercounts due to incomplete reporting by hospitals to the federal government. Tests represent the number of individual P.C.R. viral test specimens tested by laboratories and state health departments and reported to the federal government.

Outbreak clusters

Since March, The Times has paid special attention to cases in the types of places with some of the worst outbreaks, like nursing homes, food processing plants and correctional facilities.

About this data Information on cases linked to these places comes from official releases by governments, companies and institutions directly. The Times is publishing lists of groupings of 50 or more cases related to a specific site, workplace or event.

About the data

In data for Massachusetts, The Times primarily relies on reports from the state. Massachusetts typically releases new data each day. Weekend counts may be lower because fewer sources report to the state. The state reports cases and deaths based on a person*s permanent or usual residence.

The Times has identified the following reporting anomalies or methodology changes in the data:

  • Jan. 2, 2021: Massachusetts reported data for two days after reporting no data on New Year's Day.
  • Dec. 26, 2020: Massachusetts reported data for Dec. 25-26 after reporting no data on Christmas.
  • Nov. 27, 2020: Massachusetts reported data for Nov. 26 and 27 after reporting no data on Thanksgiving.
  • Sept. 2, 2020: Massachusetts revised its methodology for probable cases and deaths, removing 8,050 previously announced cases and 26 deaths.
  • Aug. 23, 2020: Massachusetts did not report new cases or deaths during data system maintenance.
  • June 30, 2020: Massachusetts removed duplicate reports, causing a decrease in the total number of deaths.
  • June 1, 2020: Massachusetts started reporting probable cases and deaths. This included the cumulative total of probable cases and deaths going back to March 1, leading to a large one-day increase.
  • April 24, 2020: Massachusetts announced a backlog of cases from earlier in April.
  • As of Aug. 12, Massachusetts reports only lab-confirmed cases by county. The state previously included probable cases. Massachusetts did not report county-level updates from Aug. 12-17.

The tallies on this page include probable and confirmed cases and deaths.

Confirmed cases and deaths, which are widely considered to be an undercount of the true toll, are counts of individuals whose coronavirus infections were confirmed by a molecular laboratory test. Probable cases and deaths count individuals who meet criteria for other types of testing, symptoms and exposure, as developed by national and local governments.

Governments often revise data or report a single-day large increase in cases or deaths from unspecified days without historical revisions, which can cause an irregular pattern in the daily reported figures. The Times is excluding these anomalies from seven-day averages when possible.
