Massachusetts health officials reported another 1,796 confirmed COVID-19 cases -- the most in one day since mid-April -- and 11 new deaths Wednesday.
The report pushed the state's number of confirmed COVID-19 cases to 711,395 since the start of the pandemic and its death toll to 17,885. The last time more than 1,796 new cases were reported in one day was April 16.
Massachusetts' COVID metrics, tracked on the Department of Public Health's interactive coronavirus dashboard, are far lower than they were several months ago, though they 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.
