The following guidance is provided for definitions and management of contacts of people with COVID-19. Separate guidance is available for international travelers. Healthcare personnel (HCP) should follow CDC’s Interim U.S. Guidance for Risk Assessment and Work Restrictions for Healthcare Personnel with Potential Exposure to COVID-19 regarding work restrictions if they have potential exposure to people with COVID-19. However, such HCP should also follow this Guidance for Community-Related Exposure for what to do in the community. See also CDC’s guidance for Implementing Safety Practices for Critical Infrastructure Workers Who May Have Had Exposure to a Person with Suspected or Confirmed COVID-19. Individuals should always follow guidance of the state and local authorities.
Public health recommendations have been updated to accommodate new scientific evidence, evolving epidemiology, and the need to simplify risk assessment. New recommendations are based on:
- Growing evidence of transmission risk from infected people without symptoms (asymptomatic) or before the onset of recognized symptoms (presymptomatic);
- Increased community transmission in many parts of the country;
- A need to communicate effectively to the general public;
- Continued focus on reducing transmission through social distancing and other personal prevention strategies.
Summary of Changes:
On June 4, 2020
- Added exposure to people with confirmed COVID-19 who have not had any symptoms to this Guidance.
Current guidance based on community exposure, for people exposed to people with known or suspected COVID-19 or possible COVID-19
|Person||Exposure to||Recommended Precautions for the Public|
Note: This is irrespective of whether the person with COVID-19 or the contact was wearing a mask or whether the contact was wearing respiratory personal protective equipment (PPE)
|All U.S. residents, other than those with a known risk exposure||
*For the purpose of this guidance, fever is defined as subjective fever (feeling feverish) or a measured temperature of 100.4°F (38°C) or higher. Note that fever may be intermittent or may not be present in some people, such as those who are elderly, immunocompromised, or taking certain fever-reducing medications (e.g., nonsteroidal anti-inflammatory drugs [NSAIDS]).
Integration of these definitions and actions into communications and actions of public health authorities can be guided by CDC’s “Implementation of Mitigation Strategies for Communities with Local COVID-19 Transmissionpdf icon”
