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 rate without higher ed results, the state data offers a cleaner picture of the actual positive rate in Massachusetts.


Coronavirus In The Hospital
