Introduction
While coronavirus disease 2019 (COVID-19) has spread rapidly worldwide, evidence on effective treatments for it is scant. To the best of our knowledge, we describe here the first report on patients undergoing a successful treatment consisting of a combination of antiviral agents that included favipiravir.
Informed consents from the patients were obtained, and a written consent for publication in this journal was also obtained from each patient. The ethics committee of the Komatsu Municipal Hospital approved the off-label use of both lopinavir/ritonavir and favipiravir before the administration of each drug.
