Should the CDC Change Its Close Contact Definition?

Whether or not the definition changes should be based on what we understand about how COVID-19 is transmitted, particularly with new variants that are more infectious, David Souleles, MPH, director of the COVID-19 Response Team at the University of California, Irvine, told Verywell in an email. “If there were to be a change, I think it should be based on a thorough review of epidemiological data and studies accumulated over the course of the pandemic,” he said.
