CDC Guidance for Employees Following a COVID-19 Diagnosis or Exposure

On April 4, 2020, the Centers for Disease Control and Prevention (CDC) issued guidance for discontinuing home isolation following a COVID-19 diagnosis. The CDC also issued guidance for what essential workers should do following exposure to COVID-19.

 

CDC Guidance for Discontinuing Isolation Following a COVID-19 Diagnosis 

The decision to discontinue isolation should be made in the context of local circumstances. Options now include both a time-since-illness-onset and time-since-recovery (non-test-based) strategy, and test-based strategy. 

Time-since-illness-onset and Time-since- recovery (non-test-based) Strategy

Persons with COVID-19 who have symptoms and directed to care for themselves may discontinue isolation under the following conditions: 

• At least three days (72 hours) have passed since recovery defined as resolution of fever without the use of fever-reducing medications, and 
• Improvement in respiratory symptoms (e.g., cough or shortness of breath), and 
• At least seven days have passed since symptoms first appeared. 

 

Test-based Strategy 

Previous recommendations for a test-based strategy remain applicable; however, a test-based strategy is contingent on the availability of ample testing supplies and laboratory capacity and convenient access to testing. For jurisdictions that choose to use a test-based strategy, the recommended protocol has been simplified so that only one swab is needed at every sampling.

 

Individuals Who Have COVID-19 and Symptoms 

Persons who have COVID-19 who have symptoms and directed to care for themselves at home may discontinue isolation under the following conditions: 

• Resolution of fever without the use of fever-reducing medications, and 
• Improvement in respiratory symptoms (e.g., cough or shortness of breath), and 
• Negative results of an FDA Emergency Use Authorized molecular assay for COVID-19 from at least two consecutive nasopharyngeal swab specimens collected ≥24 hours apart (total of two negative specimens).

 

Individuals Who Have COVID-19 Without Symptoms

 Persons with laboratory-confirmed COVID-19 who have not had any symptoms may discontinue isolation when at least seven days have passed since their first positive COVID-19 diagnostic test and have had no subsequent illness provided remain asymptomatic. For three days following discontinuation of isolation, these persons should continue to limit contact (stay 6 feet away from others) and limit the potential of dispersal of respiratory secretions by wearing a covering for their nose and mouth whenever they are in settings other persons are present. This covering may be a barrier mask in community settings, such as a bandana, scarf, or cloth mask. The cover does not refer to a medical mask or respirator.

 

CDC Guidance for Essential Workers Who Have Been Exposed to COVID-19

To ensure continuity of operations of essential functions, the CDC advises that critical infrastructure workers may be permitted to continue work following potential exposure to COVID-19, provided they remain asymptomatic, and additional precautions are implemented to protect them and the community. 

A potential exposure means being a household contact or having close contact within 6 feet of an individual with confirmed or suspected COVID-19. The time frame for having contact with an individual includes 48 hours before the individual became symptomatic.

Employers of critical infrastructure workers who have had exposure but remain asymptomatic should adhere to the following practices before and during their work shift: 

• Prescreen—Measure the employee’s temperature and assess symptoms before they are starting work. Ideally, temperature checks should happen before the individual enters the facility. 
• Practice regular monitoring—As long as the employee doesn’t have a temperature or symptoms, they should be advised to self-monitor under their employer’s occupational health program’s supervision. 
• Wear a mask—Require the employee to wear a face mask while in the workplace for 14 days after the last exposure. Employers can issue facemasks or can approve employees supplied cloth face coverings in the event of shortages.
• Social distance—Ensure that the employee maintains 6 feet of distance from others and practices social distancing as work duties permit in the workplace.
• Disinfect and clean workspaces—Clean and disinfect all areas such as offices, bathrooms, common areas, and shared electronic equipment routinely.

 

If the employee becomes sick during the day, they should be sent home immediately. Surfaces in their workspace should be cleaned and disinfected. Information on persons who had contact with the ill employee during the time the employee had symptoms and two days before symptoms should be compiled. Others at the facility with close contact within 6 feet of the employee would be considered exposed. 

Employers should implement the recommendations in the Interim Guidance for Businesses and Employers to Plan and Respond to Coronavirus Disease 2019 helps prevent and slow the spread of COVID-19 in the workplace. Additional information about identifying critical infrastructure during COVID-19 can be found on the DHS CISA website or the CDC’s specific First Responder Guidance page.
