The numbers will not match the daily reports from the State of Massachusetts for several reasons:
- Some people are tested more than once (for example, as a confirmation or re-test, or as part of an ongoing college/university testing program). The figures here reflect the number of tests performed, not the number of people tested.
- Broad Institute processes some tests from other states.
The "percent positive" pertains to the tests submitted to Broad. Because different organizations use different criteria for selecting individuals for testing, it is not possible to draw meaningful conclusions about infection rates or trends from these data.
