Work-up algorithm for the study of suspected cases of acute SC2 infection in Pediatric Emergency Room.

^aDone in the previous 3 months, except in special cases; ^bOr not done; ^cWith positive antigenic test, no PCR confirmation is required. The presence of fever, cough, odynophagia, respiratory distress, ageusia, anosmia, and gastrointestinal symptoms are considered suggestive symptoms of COVID-19. Isolated rhinorrhea would not be considered clinically suggestive (also take into account the family epidemic environment and context); ^dIf the patient already had a confirmed infection by PCR or presents positive SC2-IgG in the previous 3 months, it is not recommended to perform the antigenic test or PCR, except in special cases (immunosuppressed or cohabitants at risk or need for admission).
