This systematic review included the results of 14 studies (1 from Spain and 13 from China), with data on COVID-19 in a total of 410 children. The analysis found that across all of the studies, 40% of the COVID-19 cases in children were asymptomatic and 84% of child cases also had a family member with a confirm diagnosis, indicating a family cluster infection. Ten percent (10%) of children with COVID-19 were found to have coinfections; the most common pathogens detected among coinfections were influenza or parainfluenza viruses and Mycoplasma pneumonia.
