The City and the Public Health Department's COVID-19 Data Center presents charts, maps, and other information on COVID-19 in Cambridge. Recently, several changes have been made. A chart displaying the total number of Cambridge cases who have recovered from COVID-19 replaced two charts that showed recoveries over time. The time-based charts were discontinued because a substantial portion of recovered cases were missing a date of recovery and therefore could not be displayed. Due to this change, the number of reported recoveries increased significantly. In addition, the Data Center now shows a breakdown of Cambridge cases by classification: confirmed cases (positive viral test) and probable cases (positive antibody test or clinical diagnosis). Data include:

In November 2020, the City of Cambridge began collecting and analyzing COVID-19 data from municipal wastewater which can serve as an early indicator of increased COVID-19 infections in the city. The Cambridge Public Health Department and Cambridge Department of Public Works are using technology developed by Biobot, a Cambridge based company, and partnering with the Massachusetts Water Resources Authority (MWRA). This Cambridge wastewater surveillance initiative is being funded through a $175,000 appropriation from the Cambridge City Council.
