The death toll from confirmed cases of the coronavirus in Massachusetts rose by 29 to 8,360, state officials reported Wednesday, and the number of cases climbed by 356, bringing the total to 109,096.

The case number marks the first time the state has reported more than 300 new cases since June 27 and the first time it’s been over 350 cases since June 11.

In a statement, the Department of Public Health explained that the total was inflated by delayed reporting.

“The number of new cases reported today appears higher because a hospital group had a technical issue that caused a delay in their reporting to DPH,” the agency said in a statement. “However, these positive test results have been assigned retrospectively to the appropriate date of test.”


Key metrics the state is eyeing for its phased reopening plan hovered well below the numbers reported during the springtime surge.

The numbers come as confirmed deaths from the coronavirus in the United States hit 150,000, by far the highest toll in the world. On Wednesday, hard-hit Florida reported 216 deaths, breaking the single-day record it had set a day earlier. South Carolina’s death toll passed 1,500 this week, more than doubling over the past month.

Massachusetts has seen its own uptick in coronavirus cases recently, making some doctors uneasy. On Nantucket, the local Board of Health is mulling measures such as earlier restaurant closings in an effort to stem the spread as the island has seen a rise in cases.

In neighboring Rhode Island, new infections have risen gradually over the past month, leading Governor Gina Raimondo to reduce the state’s limit on social gatherings from 25 people to 15 and to extend Phase 3 of the state’s reopening for another month instead of moving on to Phase 4.


The state Department of Public Health on Wednesday reported no new probable-case deaths, keeping that total at 220. There were 146 new probable cases, bringing that total to 7,588.

State officials said 15,556 more people had been tested for the coronavirus as of Wednesday, bringing the total tested to 1,149,230. The total number of tests administered climbed to 1,489,896.

The state reported that new antibody tests had been completed for 1,224 people, bringing that total to 94,348.

The state is monitoring four key metrics as part of its phased reopening process. Here’s what the latest data show for each of them:

The seven-day weighted average of positive tests ticked up from 1.9 percent to 2 percent on Tuesday. That metric has generally hovered between 1.7 percent and 2 percent since mid-June. The current number represents a 93 percent drop from mid-April highs.
