Two Cases of COVID-19 Pneumonia：One Case from the Cruise ship, Diamond Princess, and the Other, A Case of Community Transmission

Abstract

We encountered two female patients with COVID-19  Eone transferred from the cruise ship, Diamond Princess, docked in the Yokohama port, and the other with community transmission of the infection The former patient had asymptomatic pneumonia, which subsided spontaneously The latter patient suffered from severe rapidly worsening pneumonia which necessitated mechanical ventilation and extracorporeal membrane oxygenation, but eventually showed complete resolution of the disease Although the lung involvement in those two cases at their first evaluation seemed to be equal, they exhibited very different clinical courses  Eone showing self-limiting asymptomatic pneumonia and the other showing severe progressive pneumonia
