The number of Mainers hospitalized with COVID-19 reached the highest figure in more than a month on Thursday.

One hundred-seven Mainers were hospitalized with the virus on Thursday, while 18 people are in critical care with two on ventilators, according to data from the Maine Center for Disease Control.

The last time the number of people hospitalized above Thursday’s point came on March 17 when 111 people were hospitalized with the virus.

The highest wastewater concentrations in the past week again came from Aroostook County, while wastewater testing sites in central and southern Maine also reported significant jumps.
