COVID-19 Cumulative Cases by Date 12/8/2020

This dataset is no longer being updated as of 12/8/2020. It is being retained on the Open Data Portal for its potential historical interest. For the more recent version of this data (which is also now historical), please visit: https://data.cambridgema.gov/Public-Safety/COVID-19-Case-Count-by-Date/axxk-jvk8 The data represented in this graph are dynamic and may change over time. Since March 20, the Cambridge Public Health Department (CPHD) has provided data regarding COVID-19 case counts based on the date that the Massachusetts Public Health Department (MDPH) reported the case to CPHD (known as report date). Beginning March 31, 2020, CPHD began providing COVID-19 case counts based on the onset time -- the date of a positive diagnosis -- which is preferable for studying disease patterns over time. Both sets of data provide the same number of total cases. CPHD often receives onset time (positive COVID-19 diagnosis) after the report date. Thus, the graph displaying onset time is recommended as a representation of the case counts per day. Daily case counts reflect the total number of cases to date, including active and recovered individuals.
