Association between time of onset and Omicron BA.2 RNA clearance time in children: a retrospective cohort study.

ABSTRACT:

Background

The association between the time of onset [time from the date of detection of a positive real-time reverse-transcription polymerase chain reaction (RT-PCR) to the date of detection of a positive RT-PCR in the first child] and viral RNA clearance time (time from first positive RT-PCR to two consecutive negative RT-PCR) remains unclear. Our study aimed to evaluate their association. That can provide a reference for the number of nucleic acid tests.

Methods

We conducted a retrospective analysis of children diagnosed with Omicron BA.2 infection at Fujian Medical University Affiliated First Quanzhou Hospital between March 14, 2022 (date the first child in the outbreak was found positive for RT-PCR) and April 9, 2022 (date the last child was found positive for RT-PCR).
