The CDC has put together the Interim Guidance for Businesses and Employers to help
Plan, Prepare and Respond to the Coronavirus in the workplace

The interim guidance may help prevent workplace exposures to acute respiratory illnesses, including COVID-19, in non-healthcare settings. The guidance also provides planning considerations if there are more widespread, community outbreaks of COVID-19.

To prevent stigma and discrimination in the workplace, use only the guidance described below to determine risk of COVID-19. Do not make determinations of risk based on race or country of origin, and be sure to maintain confidentiality of people with confirmed COVID-19. There is much more to learn about the transmissibility, severity, and other features of COVID-19 and investigations are ongoing. Updates are available on CDC’s COVID-19 web page.
