To ensure continuity of operations of essential functions, the U.S. Centers for Disease Control and Prevention advises that critical infrastructure workers may be permitted to continue work following potential exposure to COVID-19, provided they remain asymptomatic and additional precautions are implemented to protect them and the community.

A potential exposure means being a household contact or having close contact within six feet of an individual with confirmed or suspected COVID-19. The time frame for having contact with an individual includes the period of time of 48 hours before the individual became symptomatic.
