A Maricopa County COVID-19 case investigative team consisting of Arizona State University students, assisted by faculty and staff from the ASU School of Social Work in Tucson, has closed nearly 15,000 cases since June through extensive interviews and contact tracing.
Effective contact tracing involves identifying infected individuals and anyone with whom they’ve been in contact, then working with those people to halt further spread of the disease, according to the Centers for Disease Control and Prevention.
