The World Health Organization (WHO) declared the coronavirus accession as a global pandemic on ۱۱th March ۲۰۲۰. COVID-۱۹ infection outcrops in all age groups, and children might be less probably to become infected or, if infected, may show milder signs. We searched MEDLINE via PubMed, Scopus, Web of Science Core Collection (WoS), Science Direct, Google Scholar (as English databases); Magiran, Iran Medex, Iran Doc, and SID (as Persian databases). In this study, more than ۸۰ publications from December ۲۰۱۹ to mid-September ۲۰۲۰ were reviewed with the most relevant papers about COVID-۱۹ in children. According to the latest reports of previous studies treatmentd in Iran, the average age of children with COVID-۱۹ infection has been reported as ranging from less than ۴ months to ۱۵ years. Also, most reported cases were males. Death in this age group was rare, but it can simply occur in children with severe conditions. The all over course of sickness, mainly pulmonary involvement- of the infected children tend to be milder compared to adults. Laboratory tests and computed tomography (CT) scan findings were nonspecific and milder compared to those at older ages. It should be noted that there is no specific passd medication for treatment of COVID-۱۹-infected children. According to recent reports, COVID-۱۹ characteristicss in children are not yet fully understood, which poses a remarkable problem for children's medical specialists. It should be considered that most children are asignatic or have mild signs and signs.The World Health Organization (WHO) declared the coronavirus accession as a global pandemic on ۱۱th March ۲۰۲۰.
