Massachusetts reported 616 new confirmed coronavirus cases Thursday, bringing the total during the pandemic to 655,350.
The Department of Public Health also reported that another 51,764 vaccinations were administered.
The department reported 9 new confirmed coronavirus deaths, bringing the state’s total to 17,366.
The state remains in a struggle with the coronavirus more than a year after it arrived. But thanks to the state’s vaccination campaign, millions are now protected and recent coronavirus numbers have been trending downward.
The DPH said 15,833 people were estimated to have active cases of the potentially deadly virus, and 385 confirmed coronavirus patients were in the hospital.
The DPH also reported that 73,865 more tests had been conducted for coronavirus. The total number of tests administered climbed to more than 22.1 million. New antigen tests were completed for 5,236 people, bringing that total to 1,254,030.
The seven-day average rate of positive tests, which is calculated from the total number of tests administered, was at 1.15 percent.
The department said the rate would be 1.98 percent if the effect of college testing programs — in which asymptomatic people can be tested repeatedly in an effort to rapidly identify new cases — is factored out.
New data showed that only six of the state’s 351 cities and towns are considered high-risk for the virus, down from 13 communities last week and 26 the week before.
Brockton, Chicopee, Dracut, Haverhill, Littleton, Nantucket, Rochester, and Springfield dropped out of the high-risk category this week. Only Acushnet was added. Edgartown, Lawrence, Lowell, New Bedford, and Taunton remained in the red zone.
The number of new vaccinations brought the total to 6,959,591.
The number of new vaccinations reported Thursday was smaller than on Wednesday, when 58,254 were reported.
The total number of shots administered amounted to 84.1 percent of the 8,271,330 doses shipped to providers in the state so far, the DPH said.
The total shots administered included 3,870,892 first shots and 2,860,585 second shots of the Moderna and Pfizer two-shot vaccines. It also included 228,114 shots of Johnson & Johnson’s one-shot vaccine.
The number of people fully vaccinated — with either two shots of the Moderna or Pfizer vaccines or one shot of the Johnson & Johnson — rose to 3,088,699.
