Retrospective cohort study

Medical records

104 patients on the Diamond Princess cruise ship with laboratory-confirmed COVID-19 hospitalised in the Self-Defense Forces Central Hospital in Japan

The patient age ranged from 25 to 93 years (median, 68 years; IQR, 46?75??75 years), and 54 (51?9%) patients were male. Most of the patients were from Eastern Asia, with Japanese and Chinese ethnicities as the majority. The range of observation period was 3??15 days (median, 10 days; IQR, 7??10 days). Fifty-two (50?0%) patients had comorbidities.
