Introduction
In late 2019, an outbreak of pneumonia with unknown etiology was found in Wuhan, Hubei province, China. Then the pathogen was isolated soon and named the 2019 novel coronavirus (2019-nCoV) on 12 January 2020 [1] And on 11 February, the International Committee on Taxonomy of Viruses announced that its official classification is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus spread very fast in Wuhan. Even more unfortunate, as the Chinese Spring Festival is approaching, aggregation of large numbers of people flow caused it to spread quickly across the country and even spread to more than 100 countries [2]. The current case reports are mainly concentrated in Hubei Province and adults, but cases of children outside Hubei Province are rare. Meanwhile, the clinical characteristics of cases in Hubei Province and other provinces were significantly different. Here, we report the clinical manifestations, laboratory test results, imaging characteristics, and treatment regimen of nine SARS-CoV-2 infected children and their families in Jinan, Shandong province to increase awareness of this disease, especially in children.
