Massachusetts reported 1,431 new confirmed coronavirus cases Thursday, while the seven-day average edged down to 1,418 from 1,483 the day before.
The Department of Public Health also reported that the high-stakes campaign to vaccinate people administered another 94,047 shots.
The new cases brought the total number in the state during the pandemic to 636,476.
The department also reported 17 more coronavirus deaths, bringing the state’s total to 17,168.
The state remains in a struggle with the coronavirus more than a year after it arrived. Officials are racing to vaccinate the population and urging people not to let their guard down in the meantime.
The number of municipalities considered at high risk dropped to 48 from 59 last week, according to weekly data released Thursday.
The DPH said 31,215 people were estimated to have active cases of the potentially deadly coronavirus, and 645 confirmed virus patients were in the hospital.
The DPH reported that 102,071 more tests had been conducted for coronavirus. The total number climbed to more than 20.7 million. New antigen tests had been completed for 5,412 people, bringing that total to more than 1.1 million.
The seven-day average rate of positive tests, which is calculated from the total number of tests administered, was at 2 percent.
The department said the rate would be 3.59 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.
The nine municipalities added this week to the high-risk category were Bellingham, Berkley, Carver, Hampden, Palmer, Peabody, Townsend, Upton, and Winchendon.
The number of new vaccinations brought the total to 5,397,052.
The number of new vaccinations reported Thursday was greater than on Wednesday, when 93,385 were reported.
The total number of shots administered amounted to 83.5 percent of the 6,465,170 doses shipped to providers in the state so far, the DPH said.
The total shots administered included 3,216,855 first shots and 1,976,054 second shots of the two-shot vaccines from Moderna and Pfizer. It also included 204,143 shots of the one-shot Johnson & Johnson 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 2,180,197.
