This document defines four traffic flow steps for individuals at COVID-19 specimen collection sites – traffic controller, public health information gathering, specimen collection, and specimen packaging. It outlines roles for personnel at each step along with infection prevention requirements based on whether they are in a cold (traffic controller), warm (public health information gathering and specimen packaging), or hot zone (specimen collection). A list of needed resources for each specimen collection site, including the contents of each personal protective equipment kit, are also listed.
