This bulletin describes the Centers for Disease Control and Prevention (CDC) guidance for discontinuation of self-isolation for those that have been able to care for themselves at home. It is intended for employers and businesses; health care providers; and public health officials managing persons with COVID-19 (cases that received a positive PCR test for COVID-19) and under isolation who are not in health care settings. This includes, but is not limited to, at home, in a hotel or dormitory room, or in a group isolation facility.
The most recent CDC recommendations, published on July 17, 2020, no longer supports the test based strategy for self-isolated cases. According to CDC, in most cases the test-based strategy is no longer the method of choice for the discontinuation of home isolation, so it should not be used as a requirement for recovered individuals to return to the workplace, unless it has been found by a health care provider to be clinically necessary.
A test-based strategy is no longer recommended to determine when to discontinue home isolation, except in certain circumstances. A test-based strategy may result in prolonged isolation of patients who may continue to shed detectable viral RNA fragments that are no longer infectious.
Symptom-based strategy for patients with mild to moderate* illness who are not severely immunocompromised or persons with COVID-19 who have symptoms and were able to care for themselves at home may discontinue isolation under the following conditions:
- At least 10 days have passed since symptoms first appeared, and
- At least 24 hours have passed since last fever without the use of fever-reducing medications, and
- Symptoms (e.g., cough, shortness of breath) have improved
For patients who are not severely immunocompromised and who were asymptomatic throughout their infection, self-isolation and transmission-based precautions may be discontinued when at least 10 days have passed since the date of their first positive viral diagnostic test.
*Mild Illness: Individuals who have any of the various signs and symptoms of COVID-19 (e.g., fever, cough, sore throat, malaise, headache, muscle pain) without shortness of breath, dyspnea, or abnormal chest imaging.
Moderate Illness: Individuals who have evidence of lower respiratory disease by clinical assessment or imaging, and a saturation of oxygen (SpO2) ≥94% on room air at sea level.
Severe Illness: Individuals who have respiratory frequency >30 breaths per minute, SpO2 <94% on room air at sea level (or, for patients with chronic hypoxemia, a decrease from baseline of >3%), ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FiO2) <300 mmHg, or lung infiltrates >50%.
Critical Illness: Individuals who have respiratory failure, septic shock, and/or multiple organ dysfunction.
In pediatric patients, radiographic abnormalities are common and, for the most part, should not be used as the sole criteria to define COVID-19 illness category. Normal values for respiratory rate also vary with age in children, thus hypoxia should be the primary criterion to define severe illness, especially in younger children.
