To the Editor Coronavirus disease 2019 (COVID-19), which is caused by a new coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) emerged in December 2019 and led to a large-scale outbreak, mainly in Wuhan City, China. Since then, the number of patients with COVID-19 has been increasing in Japan, mostly involving adults. As of April 6, 2020, although no case has been reported in Japan, it is expected that pregnant women with COVID-19 and newborns from infected mothers will appear in the near future. Accordingly, perinatal care workers are being watchful about whether SARS-CoV-2 causes vertical transmission or infection.
