Children with COVID-19 behaving milder may challenge the public policies: a systematic review and meta-analysis
BMC Pediatrics(2020)
摘要
The emerging virus is rampaging globally. A growing number of pediatric infected cases have been reported. Great efforts are needed to cut down the transmission. A single-arm meta-analysis was conducted. We searched PubMed, Google Scholar, Web of Science, and several Chinese databases for studies presenting characteristics of children confirmed with Coronavirus Disease 2019 (COVID-19) from December 12, 2019 to May 10, 2020. Quality Appraisal of Case Series Studies Checklist was used to assess quality and publication bias was analyzed by Egger’s test. Random-effect model was used to calculate the pooled incidence rate (IR) or mean difference (MD) with 95% confidence intervals (CI), or a fixed model instead when I2 < 50%. We conducted subgroup analysis according to geographic region. Additionally, we searched United Nations Educational Scientific and Cultural Organization to see how different countries act to the education disruption in COVID-19. 29 studies with 4300 pediatric patients were included. The mean age was 7.04 (95% CI: 5.06–9.08) years old. 18.9% of children were asymptomatic (95% CI: 0.121–0.266), 37.4% (95% CI: 0.280–0.474) had no radiographic abnormalities. Besides, a proportion of 0.1% patients were admitted to intensive care units (0, 95% CI: 0.000–0.013) and four deaths were reported (0, 95% CI: 0.000–0.000). Up to 159 countries have implemented nationwide school closures, affecting over 70% of the world’s students. Children were also susceptible to SARS-CoV-2, while critical cases or deaths were rare. Characterized by mild presentation, the dilemma that children may become a potential spreader in the pandemic, while strict managements like prolonged school closures, may undermine their well-beings. Thus, the public policies are facing challenge.
