Review revealed that COVID-19 is relatively milder with better prognosis in pediatrics. However, patients with comorbidity are at higher risk. Meta-analysis of reviews showed that 21.17% (95% CI: 17.818\u201324.729) of the patients were asymptomatic and mortality rate was 0.12% (95% CI: 0.0356\u20130.246). Though there was no publication bias, significant heterogeneity was observed. Fever (48\u201364%) and cough (35\u201355.9%) were common symptoms, affecting almost every alternate patient. Ground-glass opacities (prevalence range: 27.4\u201361.5%) was most frequent radiographic observation. Rise in C-reactive protein, lactate dehydrogenase and D-dimer ranged from 14% to 54%, 12.2\u201350% and 0.3\u201367%, respectively. Some of the included reviews (44.7%-AMSTAR; 13.2%-GRADE) were of lower quality.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Current umbrella review provides most updated information regarding characteristics of COVID-19 infection in pediatrics and can be used to guide policy decision regarding vaccination prioritization, early screening and identification of at-risk population.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/qjmed\/hcab206","type":"journal-article","created":{"date-parts":[[2021,7,20]],"date-time":"2021-07-20T19:32:11Z","timestamp":1626809531000},"page":"476-495","source":"Crossref","is-referenced-by-count":12,"title":["Epidemiological, clinical and biomarker profile of pediatric patients infected with COVID-19"],"prefix":"10.1093","volume":"114","author":[{"given":"K","family":"Shah","sequence":"first","affiliation":[{"name":"Department of Public Health, Indian Institute of Public Health Gandhinagar, Opp. Air Force Head Quarters, Nr.
