Can CDC tell me or my employer when it is safe for me to go back to work/school after recovering from or being exposed to COVID-19?
section_content: CDC cannot address the policies of any business or organization. CDC shares
recommendations based on the best available science to help people make
decisions that improve their health and safety. Employers, schools, and
organizations may decide to visibly screen for symptoms or perform on-site
symptom checks.
If your employer, school, or organization requires you to present
documentation regarding COVID-19 before returning to work or school (for
example, proof of a negative COVID-19 lab test, if a test was performed,
contact your healthcare provider to ask if he or she would be able to provide
a form of documentation for you. Documentation of self-isolation and self-
quarantine may not be possible.
CDC has guidance for when and how people with COVID-19 can discontinue home
isolation: https://www.cdc.gov/coronavirus/2019-ncov/if-you-are-sick/steps-
when-sick.html.
CDC also has guidance for what people should do if they think they have been
exposed or feel sick: https://www.cdc.gov/coronavirus/2019-ncov/prevent-
getting-sick/social-distancing.html.
In all cases, follow the guidance of your healthcare provider and local
health department. Local decisions depend on local circumstances.

section_headers: Cleaning and Disinfection
How long do companies need to close for disinfection after an exposure? How long before other workers can come back to work?
section_content: Companies do not necessarily need to close after a person with confirmed or
suspected COVID-19 has been in a company facility. The area(s) used or visited
by the ill person should be closed for 24 hours or as long as possible. Open
outside doors and windows as much as possible ensuring that doing so does not
pose a safety risk to children using the facility (i.e. make sure that
children are not able to enter the closed off area through any windows or
doors). and use ventilating fans to increase air circulation in the area. Once
the area has been appropriately
disinfected, it can be opened for use. Workers without close contact with
the person with confirmed or suspected COVID-19 can return to work immediately
after disinfection is completed.

Reviewer feedback on this answer:
The answer gave information about steps to be taken in the event of COVID-19.
The question is about CDC notifications to business and this doesn't touch on that. This really only talks about coming back to work after exposure which mostly misses the point

page_title: General Business Frequently Asked Questions
section_headers: Suspected or Confirmed Cases of COVID-19 in the Workplace
What should I do if I find out several days later, after an employee worked, that they were diagnosed with COVID-19?
section_content: 
If it has been less than 7 days since the sick employee used the facility, clean and disinfect all areas used by the sick employee following the CDC cleaning and disinfection recommendations.
If it has been 7 days or more since the sick employee used the facility, additional cleaning and disinfection is not necessary. Continue routinely cleaning and disinfecting all high-touch surfaces in the facility.
Other employees may have been exposed to the virus if they were in “close contact” (within approximately 6 feet or 2 meters) of the sick employee for a prolonged period of time. 
Those who have symptoms should self-isolate and follow CDC recommended steps.
In most workplaces, those potentially exposed but with no symptoms should remain at home or in a comparable setting and practice social distancing for 14 days.
Critical infrastructure workers should follow Implementing Safety Practices for Critical Infrastructure Workers Who May Have Had Exposure to a Person with Suspected or Confirmed COVID-19. A critical infrastructure worker who is symptom-free and returns to work should wear a face mask at all times while in the workplace for 14 days after last exposure. Employers can issue facemasks or can approve employees’ supplied cloth face coverings in the event of shortages.


Employees not considered exposed should self-monitor for symptoms such as fever, cough, or shortness of breath. If they develop symptoms, they should notify their supervisor and stay home.


Reviewer feedback on this answer:
This mostly talks about the self quarantine period but this isn't what the question was asking. They wanted to know about what the CDC does and doesn't tell businesses which isn't mentioned here
the response contains guidelines from official organizations.
