This document summarizes the CDC’s guidelines for isolation and quarantine to help employees
and employers assess when an individual can return to work after a confirmed case of COVID-
19 or after close contact with a confirmed case of COVID-19. Neither the Centers for Disease
Control and Prevention (CDC), Occupational Safety and Health Administration (OSHA), or the
Equal Employment Opportunity Commission (EEOC) recommend that employers require
employees to obtain a note from a doctor or other health care provider before returning to
work after a COVID-19 diagnosis or close contact. Instead, employers are urged to develop
policies that align with these guidelines and recommendations in regards to employee return to
the workplace after a confirmed case of COVID-19 or a close contact with a confirmed case of
COVID-19. Employees are cautioned that this document is general guidance, and employees
should consult with their individual employers for policies applicable to their situation.
Guidelines and Recommendations
Positive Cases
Individuals who have tested positive for COVID-19 should isolate for 5 days after onset of symptoms
(onset day is Day 0), or 5 days after the date of specimen collection of positive test if no symptoms are
present (specimen collection date is Day 0). If an individual is fever-free for 24 hours (without the use of
fever-reducing medication) and their symptoms are improving after 5 days, they are released from
isolation (on Day 6) but need to continue to wear a well-fitting mask for the next 5 days when around
others, including at home.
Close Contacts
Individuals who have been in close contact with a confirmed case of COVID-19 should follow the
quarantine guidelines below depending on whether they have been vaccinated or have had a confirmed
case of COVID-19 within the past 90 days.
If an individual had a confirmed case of COVID-19 within the past 90 days, confirmed with a
viral test (antigen or PCR), OR is up-to-date on recommended COVID-19 vaccinations, including
booster doses, they:
• Do not need to quarantine if they do not have any COVID-19-like symptoms, but should wear a
mask around others for 10 days from the date of last close contact, and test 5 days after the
date of last exposure.
• Should watch for symptoms until 10 days after date of last close contact with someone with
COVID-19. If COVID-19-like symptoms develop, they should immediately isolate from others
until a negative test result confirms that symptoms are not caused by COVID-19.
