Amid a recent surge of new COVID-19 cases among younger adults, an additional 589 new infections were reported Thursday, pushing the number of cases past the 40,000 mark.
Altogether, 40,163 people are known to have caught COVID-19, including 1,490 who have died.
Five more deaths due to the new coronavirus were announced, with four among residents of long-term care facilities.
In the past week, the number of COVID-19 cases among people in their 20s increased 13%. With 8,990 cases since the pandemic began, they are the largest age group of those who have been sickened.
"Young people from across the state are accounting for the bulk of cases in the last two weeks," Kris Ehresmann, state infectious disease director, said Wednesday.
Many of the exposures are happening at bars and restaurants, she noted.
While the reopening of those establishments was expected to lead to more COVID-19 cases, Ehresmann has said that wearing masks and maintaining social distancing can help control the growth rate of new cases.
An additional concern is that once infected, younger adults will spread the disease to others in the community, including those who are most vulnerable to COVID-19 complications.
