To evaluate the severity and clinical outcomes of the SARS-CoV-2 gamma variant in children and adolescents hospitalized with COVID-19 in Brazil. In this observational retrospective cohort study, we performed an analysis of all 21,591 hospitalized patients aged < 20 years with confirmed SARS-CoV-2 infection registered in a national database in Brazil. The cohort was divided into two groups according to the predominance of SARS-CoV-2 lineages (WAVE1, n = 11,574 and WAVE2, n = 10,017). The characteristics of interest were age, sex, geographic region, ethnicity, clinical presentation, and comorbidities. The primary outcome was time to death, which was evaluated by competing-risks analysis, using cumulative incidence function. A predictive Fine-Gray competitive risks model was developed based on WAVE1 cohort with temporal validation in WAVE2 cohort.

The COVID-19 pandemic resulted in unprecedented implementation of wide-ranging public health measures globally. During the pandemic, dramatic decreases in seasonal influenza virus detection have been reported worldwide. Information on the impact on paediatric influenza-related hospitalisations is limited. This study describes influenza-related hospitalisation in children in Canada following the onset of the COVID-19 pandemic. Data on influenza-related hospitalisations, intensive care unit (ICU) admissions and in-hospital deaths in children across Canada were obtained from the Canadian Immunisation Monitoring Program, ACTive (IMPACT). This national active surveillance initiative comprises 90% of all tertiary care paediatric beds in Canada. The study period included eleven influenza seasons, from the 2010/2011 season until the 2020/2021 season inclusive. Time series modelling was used to compare the observed to predicted influenza-related hospitalisations following the COVID-19 pandemic.

There is an urgent need to inform policy deliberations about whether children with asthma should be vaccinated against SARS-CoV-2 and, if so, which subset of children with asthma should be prioritised. The authors were asked by the UK's Joint Commission on Vaccination and Immunisation to undertake an urgent analysis to identify which children with asthma were at increased risk of serious COVID-19 outcomes. This national incident cohort study was done in all children in Scotland aged 5–17 years who were included in the linked dataset of Early Pandemic Evaluation and Enhanced Surveillance of COVID-19 (EAVE II).

Coronavirus disease (COVID-19) is milder with favorable outcomes in children than in adults. However, detailed data regarding COVID-19 in children from Saudi Arabia are scarce. This study aimed to describe COVID-19 among children in Al-Madinah, Saudi This retrospective observational study included children <14 years old hospitalized with COVID-19 between May 1, 2020 and July 31, 2020. Clinical data, COVID-19 disease severity, and outcomes were collected. The total number of presenting symptoms and signs were computed by counting those recorded upon presentation. The Kruskal-Wallis non-parametric test was used to compare the number of symptoms and signs across all levels of COVID-19 severity.

There is limited research on children infected with Covid-19 after initial diagnosis. The aim of this study was to describe changes in symptoms in children infected by Covid-19 after 1st and 3rd months of diagnosis. Covid-19 patients age under 18 admitted to the Dokuz Eylul University Hospital, Izmir, Turkey during December 2020 (n = 144) and completed three months follow-up (n = 123) were included in this prospective cohort study. Data on age, sex, parents' educational status, perceived economic status, presence of Covid-19 patient at household, chronic diseases history, initial and existing symptoms and perception of recovery were collected via telephone interviews. Persistent symptom was defined as any symptom reported within a week of the interview. Chi-square and Mann-Whitney U Test were used for univariate analyses.

This study aims to o assess the impact of the COVID-19 pandemic on rates of hospital visitation and rates and durations of developmental care practices for infants born preterm. It analyzed electronic medical record data from 129 infants born at less than 32 weeks gestational age (GA) cared for in the Lucile Packard Children's Hospital neonatal intensive care unit (NICU) in a COVID-19-affected period (March 8, 2020 to Nov 30, 2020, n = 67) and the analogous period in 2019 (n = 62). Rates of family visitation and of family- and clinical staff-delivered developmental care were compared across cohorts, adjusting for covariates.

This study aimed to capture key epidemiological data on SARS-CoV-2 infection in Nicaraguan children (≤18 years) seeking medical care, between 6 October and 16 November 2020. In this cross-sectional study, 418 children were recruited: 319 with symptoms characteristic of COVID-19 and 99 with no symptoms of illness. Children were tested for SARS-CoV-2 RNA using loop-mediated isothermal amplification. A questionnaire was employed to identify symptoms, risk factors, comorbidities and COVID-19 prevention measures. Research was carried out in four hospitals and two clinics in Managua, Nicaragua, where schools and businesses remained open throughout the COVID-19 pandemic.
