SARS-CoV-2/COVID-19 ha amenazado con bloquear los circuitos asistenciales habituales. En este sentido, la detección
de SARS-CoV-2 en pacientes con necesidad de contacto reiterado con el sistema sanitario ha obligado a establecer
estrategias seguras de control clínico y de negativización.
Se analizaron los datos de los pacientes diagnosticados
de infección por SARS-CoV-2 mediante PCR en muestra respiratoria entre el 11 de marzo y el 30 de abril de 2020 en
un hospital terciario pediátrico de referencia de Barcelona
(España), a los que se hubiera practicado posteriormente
un nuevo estudio para comprobar la negativización de la
PCR en aspirado nasofaríngeo. Dicho estudio se realizó a
pacientes con necesidad de asistencia seriada en hospitales de día, procedimientos, hospitalizaciones programadas,
etc. Para estos controles clínicos y de negativización, y pos357
