The COVID-19 pandemic in Massachusetts is part of an ongoing pandemic of coronavirus disease 2019 (COVID-19) in the U.S. state of Massachusetts. The first confirmed case was reported on February 1, 2020, and the number of cases began increasing rapidly on March 5. Governor Charlie Baker declared a state of emergency on March 10. By March 12, more than a hundred people had tested positive for the virus. Most early cases were traceable to a company meeting held in Boston in late February by the Cambridge-based biotechnology firm Biogen. In May, Massachusetts was third in the U.S. for both overall number of cases and for cases per capita, behind New York and New Jersey.[4]

Massachusetts experienced a first wave of COVID-19 that peaked in April and May 2020 with almost 4,000 people hospitalized with the disease, and nearly 3,000 new cases and 200 deaths a day. A second wave began in the autumn of the same year, with a large spike in cases beginning in October and, in the first days of December, daily case numbers surpassing those seen at the height of the first wave.[5][6] As of March 18, 2021, Massachusetts was experiencing a rolling average of 1,543 new confirmed cases and 26 confirmed deaths per day.[7][g]

As of March 30, 2021, Massachusetts had the 17th-highest number of cases in the United States, and the 34th-highest number of cases per capita. It had the 11th-highest number of deaths due to the virus, and the third-highest number of deaths per capita, behind New York and New Jersey.[8] There had been 633,081 total COVID-19 cases and 17,148 deaths among cases of COVID-19 in Massachusetts since the beginning of the pandemic. 52% of confirmed and probable deaths were among residents of long-term care facilities. The state had tested more than 5.1 million people for the virus via molecular test, and more than 645,000 via antigen test.[1]
