As of mid-2025, the CDC no longer mandates a strict 5-day isolation for children with COVID. Instead, children can return to school once their symptoms are improving and they’ve been fever-free without fever‑reducing medication for a full day. But they should still take extra precautions—masking, hygiene, distancing—for five full days after returning. 

If asymptomatic, students may return immediately, but take extra precautions—masking, hygiene, distancing—for 5-10 days after returning.
