The coronavirus disease (COVID-19) outbreak that occurred in Wuhan City, Hubei Province, China in December 2019 has developed into a global pandemic. Even now, the number of people that are infected, seriously ill, and dead continues to increase, and the disease spread is showing no signs of slowing down. In Japan as well, the number of COVID-19 patients without any traveling history or contact history is increasing, and there is a concern that this disease will spread in Japan. Many patients have reported dry cough and fever as clinical symptoms, but the clinical manifestations can range from asymptomatic to multiple organ failure. It is rarely severe in children, but there are some pediatric cases presenting serious symptoms including hypotension, shock, and acute heart failure.
There are relatively fewer studies on pediatric COVID-19 than adult COVID-19, and Japan has limited reports of pediatric cases.
A 2-month-old boy was admitted to our hospital for fever. Though his general condition was good, he was hospitalized due to his young age and because his father had fever, dysgeusia, and olfactory dysfunction 10 days prior to the first visit and was suspected of having COVID-19. Pharyngeal swabs were collected from both infant and father, and polymerase chain reaction (PCR) was performed for severe acute respiratory syndrome coronavirus 2, which showed positive results. The infant was hospitalized for 11 days, but the course of illness mainly presented mild upper respiratory symptoms. Pharyngeal PCR was conducted again on day 17 after onset, which showed a negative result.
