PORTLAND, Maine (AP) — The Long Creek Youth Development Center in South Portland is testing all staff and residents for the new coronavirus after a youth detainee tested positive for the virus. The Maine Department of Corrections announced the decision to adopt universal testing Sunday after learning of the positive test result. Officials say the youth was tested Friday before being released, and test results became available Saturday. Officials say the minor who tested positive was asymptomatic while at the detention center and is now self-quarantining. Maine has reported more than 3,100 cases of the virus along with 104 deaths.
