Massachusetts’ Governor Charlie Baker announced a crisis after the state’s coronavirus cases more than doubled overnight, surging by 51 new cases.

“Today there are 51 new presumptive positive cases of COVID-19, bringing the total number of confirmed or presumptive positive cases in the commonwealth to 92,” said Marylou Sudders, secretary of Massachusetts’ health and human services.

Sudders said 70 of the total cases all originate from a meeting of senior managers at Biogen Inc. in the Boston zone before the end of last month. Presumptive positive cases have been affirmed by state or local labs, however not by the Centers for Disease Control and Prevention.

The presentation of a crisis gives the state greater adaptability to react to the advancing outbreak, Baker said.

“We believe it’s important to start taking more aggressive action now to mitigate spread based on the information we have available. There’s no question that the efforts to mitigate the spread of this virus will be disruptive. We expect this disruption to continue for the foreseeable future and understand it will cause inconvenience for many,” Baker said during a press conference.

Baker included that the state’s department of public health would give guidance to local superintendents on how to address cases that show up at schools, including closures.

Prior in the day, Harvard University told its students that it would hold all classes online for the remainder of the spring term and instructed students to vacate the campus by Sunday.

Massachusetts, where Harvard is found, had one affirmed case of COVID-19 and 40 presumptive cases as of Tuesday morning, as indicated by the state’s department of public health. There are as of now 249 individuals experiencing monitoring or under quarantine in the state.

The decision comes as COVID-19 has cleared over the U.S., tainting at least 805 in the U.S. and killing at least 28 as of Tuesday afternoon, as indicated by information assembled by Johns Hopkins University.
