COVID-19 School Return Guidelines

Standard Isolation Period

• The American College of Cardiology recommends that students who test positive for COVID-19 should stay out of school for at least 5 days from symptom onset or positive test date, and may return after being fever-free for 24 hours without fever-reducing medications and showing symptom improvement 1, 2, 3, 4.
• The Centers for Disease Control and Prevention (CDC) stipulates a minimum 5-day isolation period from symptom onset or date of positive test if asymptomatic 1, 2, 3, 4.

Important Considerations for School Return

• Asymptomatic students can return after 5 days of isolation, provided they remain symptom-free 1, 2, 3, 4.
• The 5-day count begins from symptom onset, not test date 1, 2, 3, 4.
• Students must demonstrate clinical improvement before returning 6, 7, 8.
• Isolated loss of smell or taste should not delay return to school 1, 2, 3.

Special Populations Requiring Extended Isolation

• Severely ill students or those on immunosuppressive medications require individualized assessment and may need isolation beyond 10 days 5.

Testing-Based vs. Symptom-Based Strategy

• The CDC primarily recommends a symptom-based approach rather than requiring negative tests for school return 6, 7, 8.
• A test-based strategy may be used in specific circumstances, including two consecutive negative PCR or NAAT tests collected ≥24 hours apart 6, 7, 8.

Return to Physical Education and Sports

• Asymptomatic or mild non-cardiopulmonary symptoms require 3 days of exercise abstinence during the isolation period 1, 2, 3, 4.
• Students with cardiopulmonary symptoms require cardiac evaluation before returning to sports (ECG, troponin, echocardiogram) 1, 2, 3, 4.

Common Pitfalls to Avoid

• Do not require negative tests for routine school return - this is not part of CDC guidance and can unnecessarily prolong absences 6, 7, 8.
• Do not count isolation days from test date if symptoms began earlier - always count from symptom onset 1, 2, 3, 4.
• Do not delay return for isolated loss of smell/taste - these symptoms may persist for weeks without indicating ongoing infectiousness 1, 2, 3.
