HARTFORD, Conn. (AP) - Connecticut teachers have many questions as they return to the classroom for in-person learning this fall. State officials say some of the answers may come from the day care centers that have remained open during the coronavirus pandemic. Between 1,500 and 1,900 child care programs have stayed open since March. There have been fewer than 50 reported COVID-19 cases among those centers and only 10 among children, according to the state's Office of Early Childhood. By keeping children in small groups and teaching social distancing, the office says the day cares and day camps have had an infection rate of less than 1 case per 1000 people tested.
