The coronavirus disease 2019 (COVID-19) pandemic has been observed in Japan since March 2020. This study investigated the retrospective clinical backgrounds of patients tested for SARS-CoV-2 at this hospital. During this period, 325 cases were included, of which, 15 (positive rate 4.6%) were positive for SARS-CoV-2. They had a history of more significant contact with COVID-19 patients when compared to the 310 negative cases (p=<0.0001). The symptom of fever was most common among the positive cases with symptoms (8/11 cases). However, no significant difference was found between positive and negative cases. Olfactory and taste disorder was significantly more common in the positive cases than in the negative ones (p=0.0039). It was difficult to distinguish the symptoms between the positive and negative cases. Contact history presented by interview is useful for identifying COVID-19 in children.
