Contact tracing is what is now on everyone’s radar in order to help in the next step to begin to open up the country. Contact tracing is a process designed to halt the chain of transmission of an infectious pathogen–like the coronavirus–and slow community spread. When someone tests positive for an infectious disease, they become a “case.” Public health workers then reach out to the case to make sure they have what they need and that they are self-isolating. They will then figure out who they had contact with who may be at risk of infection, too. NPR recently released a guide on the basics of the process and how it might help society restart after the current wave of coronavirus cases.
