COLOMBIA, SC (AP) – The South Carolina Department of Health reports that it is giving up trying to track each individual case of coronavirus in the state. The Department of Health and Environmental Control said Thursday that it was moving from a “containment” approach to a “mitigation” approach. This means that contact trackers will focus on exposed domestic contacts and people in places where widespread dissemination is possible. Health officials say people should no longer expect to receive calls from contact trackers if they are exposed to a case. The agency said on Thursday that it will now allow medical students, retired nurses and other qualified professionals to administer the COVID-19 vaccine.
