The Latest Numbers
The above numbers include the cases and deaths confirmed each day by the Department of Public Health (DPH). But because of a lag in reporting, a case could have been diagnosed or a person may have died earlier. To get a more accurate picture of the day-by-day change, scroll down to the interactive charts below.
Each day, the state releases a dashboard of its data tracking cases and deaths by age, race, sex and geography. You can look at the complete data in the state's daily report.
The below map reflects state health officials' risk determination for each community in Massachusetts. Municipalities with the highest rates of infection are marked in red and considered "high risk," followed by yellow and green. Communities in grey have the fewest cases and lowest rates of transmission. More information about the risk levels is here.
The state updates data on deaths and cases by city and town once a week, on Thursdays. Click on the interactive above to see the latest case count in your community.

Tracking New Confirmed Cases And Deaths
Each of the graphs below track the number of new cases or deaths by the day diagnosed. It often takes a few days for hospitals, labs and other facilities to report the data.
You may note that the charts show a sharp drop-off for the last few days. Keep in mind that may not mean an actual decrease in the numbers, but a delay in the state's reporting.
Tracking The State's Positive Test Rate
The graph below shows how many tests taken by residents have come back positive — that's the state's positive test rate.
The orange line shows that rate excluding results from colleges and universities, where students and staff are tested multiple times a week. Because of that, the same person can contribute multiple negative tests and inadvertently skew the positive rate downward. In providing the second, higher rate by removing higher ed results, the state data offers a cleaner picture of the actual positive rate in Massachusetts.
Long-Term Care Facility Cases And Deaths
Cases inside of the state's long-term care facilities are of particular concern because the coronavirus has been especially dangerous for older people and people with existing health conditions. Deaths in these facilities account for almost two-thirds of the lives lost to COVID-19 during the pandemic. The case data provided by the state combined resident and staff cases, and does not include assisted-living facilities.
Coronavirus In The Hospital
A key metric in combating the pandemic has been hospitalization: We want to make sure that any wave of infections does not exceed our ability to treat people with the most serious cases. The following charts reflect the current capacity at the state's hospitals.
