This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Importance Adults with Down syndrome (DS) are at higher risk for severe outcomes of coronavirus disease 2019 (COVID-19), but further evidence is required to determine the exact risks for children with DS. The clinical features and epidemiological characteristics of COVID-19 in children with DS, and risk factors for severe outcomes, must be established to inform COVID-19 shielding advice and vaccination priority. Objective:
To determine risk factors for a severe course of COVID-19 in pediatric DS patients and to compare the prevalence of severe COVID-19 between pediatric patients with and without DS.Design:
This retrospective cohort study included pediatric cases (aged <18 years) with DS from the Trisomy 21 Research Society international survey and pediatric cases from the general population published by the US Centers for Disease Control and Prevention (COVID-NET) collected during the first wave of the COVID-19 pandemic (controls).Setting:
Cohorts included 328 children with DS (127 hospitalized, 39%) and 224 children without DS (all hospitalized) with COVID-19. Of the pediatric DS patients, 64.1% were from low-to-middle-income countries (LMICs), and 35.9% from high-income countries (HICs).Participants:
Clinicians, family members, or caregivers completed the survey on behalf of children with DS affected by COVID-19.Results:
Among the 328 COVID-19 patients with DS; older age, obesity, and epilepsy were significant risk factors for hospitalization; and age and thyroid disorder were significant risk factors for acute respiratory distress syndrome. The 127 hospitalized COVID-19 patients with DS had a higher incidence of cough, fever, nasal signs and shortness of breath than controls. Compared with controls, hospitalized children with DS (especially those from LMICs) had a higher prevalence of COVID-19-related medical complications (pneumonia, ARDS, acute renal failure). Conclusions and relevance Children with DS are at higher risk for severe COVID-19 than the general pediatric population. Efforts should be made to monitor the health of children and young people with DS during the ongoing pandemic and to report any COVID-19 signs and symptoms in a timely manner, especially for those who have comorbidities which are risk factors for severe COVID-19. When vaccination rollout for pediatric populations begins, children with DS should be prioritised.
