Identifying Critical Infrastructure During COVID-19

As our nation continues to labor in halting the spread of the coronavirus, states and local governments are promulgating quarantine orders and mandatory business closures. While these steps are considered important public health measures that will help limit the spread of the virus, the term “essential workforce” is easily misunderstood and debated. 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. Certain critical infrastructure industries have a special responsibility in these times to continue operations.

This guidance and accompanying list, provided by the Department of Homeland Security, are intended to support State, Local, and industry partners in identifying the critical infrastructure sectors and the essential workers needed to maintain the services and functions Americans depend on daily and that need to be able to operate resiliently during the COVID-19 pandemic response.
