Pediatric cases of the coronavirus disease 2019 (COVID-19) are generally mild or asymptomatic, and are usually detected by virological examination following close contact with COVID-19 patients, often the children's parents. The detailed clinical features and virological data of pediatric patients with COVID-19, particularly young infants, remain unclear. Here, the clinical and virological characteristics of four children with COVID-19 including two young infants were investigated. One- and 4-month-old boys with COVID-19 were both asymptomatic, and seroconversion was demonstrated. These findings suggest that even young infants can mount an immune response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), despite having weaker immune defenses than adolescents and adults. Three-year-old boy, who was SARS-CoV-2-negative, was admitted to the same room as his SARS-CoV-2-positive father due to the lack of caregivers. Although he was asymptomatic, he had seroconverted to SARS-CoV-2. Eleven-year-old boy, who was sibling of the 3-year-old boy, was also SARS-CoV-2-negative. He was isolated in his own room and did not seroconvert. If young children are SARS-CoV-2 negative, they should be isolated from their SARS-CoV-2-positive parents. This may be difficult in practice, if parents with COVID-19 are the only available caregivers. In such situations, the most appropriate measures should be taken for each patient.
