The severity of clinical outcome, personal vaccination-2 doses, household vaccination rates, and abnormal defecation were independently associated with negative conversion of viral RNA, suggesting that patients who had abnormal defecation or with more severe conditions would have delayed virological clearance, while patients who had received 2 doses of vaccination or had higher household vaccination rates would have accelerated virological clearance. This study aimed to identify the related risk factors and potential predictors of SARS-CoV-2 RNA negative conversion by describing the dynamics of viral shedding in infected children admitted to two hospitals from Shanghai during the Omicron variant outbreak.
