Massachusetts health officials reported another 1,452 confirmed coronavirus cases -- the most in a single day since April -- and 11 new deaths on Wednesday.
The report pushed the state's number of confirmed COVID-19 cases to 691,720 since the start of the pandemic and its death toll to 17,795. The last time at least 1,452 new cases were confirmed in one day was April 23.
Massachusetts' COVID metrics, tracked on the Department of Public Health's interactive coronavirus dashboard, are far lower than they were several months ago, though some have been rising in recent weeks. While breakthrough cases are being reported, officials say most new cases, and especially serious infections, are in the unvaccinated.
Massachusetts' seven-day average of positive tests fell to 2.78% on Wednesday. It was once above 30%, but had dropped under 0.5% until the delta variant began surging in the state.
