BOSTON (WPRI) — Massachusetts officials are encouraging people who have recently participated in a large gathering such as a protest to get tested for COVID-19.

Gov. Charlie Baker announced pop-up testing sites will be available at more than 50 locations around the state on Wednesday and Thursday.

The tests are free and the results will be given confidentially.

Baker warned that COVID-19 can spread easily within large groups of people in close contact, and people not experiencing any symptoms can still have the virus and spread it.

“Any time large groups of people come together, there is a risk of transmission,” he said. “We certainly support people’s rights to express their views peacefully, but we need to keep up the fight to stop the spread of COVID-19 here in Massachusetts.”

On Tuesday, the Mass. Department of Public Health reported an additional 140 confirmed cases and 55 probable cases, along with 18 more deaths.
