Clinical characteristics of patients with COVID-19 in Japan: a single-center case series

Abstract

We report a case series of 6 patients with confirmed COVID-19 in Wakayama prefecture, Japan. All 6 of the patients tested positive in pharyngeal swab PCR tests, and 2 of the 6 were still positive at 3 weeks after onset. All of the patients exhibited bilateral ground glass opacities (GGO) on computed tomography (CT). This paper also reports narrative information on the spectrum of symptoms collected directly from the patients. It would be difficult to triage patients with COVID-19 based on the typical symptoms of fever and/or cough, although PCR and CT are definitive in diagnosis.
