Maine is reporting 649 new coronavirus infections Wednesday.
That brings the seven-day average to 489. This number has generally been trending downward since the beginning of October, though it remains high.
The Maine CDC says 7 more people have died from the disease, bringing the total deaths to 1,109.
COVID-19 hospitalizations in Maine continue to hover around 200 for the third day in a row. 68 people are in critical care, and 34 need help breathing with a ventilator.
Maine CDC director Nirav Shah says it's not clear what's driving the resurgence, but new data from the U.S. CDC underscore the risk of serious illness for people who are not vaccinated.
"Nationwide, the risk of hospitalization with COVID-19 is approximately 12 times greater for individuals who are not vaccinated, as compared with those who are," Shah said.
Maine's seven-day positivity rate also remains elevated, at 5.3 percent, up from 4.3 percent two weeks ago.
