Massachusetts health officials reported another 4,838 confirmed COVID-19 cases -- the most in one day since January -- and 25 new deaths Wednesday, as the state's death toll surpassed 19,000 and its positive test rate continued to surge.
The report from the Department of Public Health pushed the state's number of confirmed COVID-19 cases to 860,280 since the start of the pandemic and its death toll to 19,016.
The last time Massachusetts reported more than 4,838 COVID cases over one day was on Jan. 22, as last winter's surge was receding.
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. The discovery of omicron, a new COVID strain labeled a variant of concern by the World Health Organization over the Thanksgiving weekend, is being monitored in case it accelerates the recent surge statewide and across the U.S. -- though no cases have been identified in the Massachusetts so far.
