The Centers for Disease Control and Prevention (CDC) has issued a guidance document titled Testing Strategy for COVID-19 in High-Density Critical Infrastructure Workplaces after a COVID-19 Case is Identified (the Guidance), which describes different testing strategy options for exposed employees when companies determine testing is needed to help support existing disease control measures. As part of the Guidance, CDC issued a decision tree to assist with determining optional testing strategies. CDC specifically notes that outbreaks of illness among workers in food producing facilities and surrounding communities have raised “unique questions that identified the need for testing” to supplement existing CDC recommendations. CDC explains the Guidance is intended to supplement and augment existing guidance with the goal of reducing transmission of SARS-COV-2 in the workplace.
