See full answer Functioning critical infrastructure is imperative during the response to the COVID-19 emergency, for both public health and safety as well as community well-being. When continuous remote work is not possible, critical infrastructure businesses should use strategies to reduce the likelihood of spreading the disease. This includes, but is not necessarily limited to, separating staff by off-setting shift hours or days and implementing social distancing. These steps can preserve and protect the workforce and allow operations to continue. To ensure continuity of operations of essential functions, CDC 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.
