Massachusetts health officials reported another 3,196 confirmed COVID-19 cases -- the most in one day since February -- and eight new deaths Thursday.
The report pushed the state's number of confirmed COVID-19 cases to 826,996 since the start of the pandemic and its death toll to 18,834.
The number of new confirmed cases in Wednesday's report from the Department of Public Health had been the most in one day since September, according to archival data. But that report included "a backlog of testing results" from several prior days. The prior single-day high had been in February -- and Feb. 6 was the last time more than 3,196 cases were confirmed in one day.
Massachusetts' COVID metrics, tracked on the Department of Public Health's interactive coronavirus dashboard, dashboard, had been far lower than they were in spring, but have been rising lately.
