Using an online questionnaire, we asked Japanese board-certified radiologists to register their patients' information including patient age and sex, the CT examination date, the results of PCR test for COVID-19 infection, CT findings, and the postal code of the medical institution that performed the CT. We conducted the present study to reveal that CT-surveillance could demonstrate the epidemiologic features of COVID-19 infection as well as simultaneously investigate the type and frequency of characteristic imaging findings on CT by using clinical CT data. CT findings in CT surveillance might distinguish the group that is considered Fig. 2 The epidemic curve of the diurnal patient number in the CT surveillance (a) shows a distribution similar to that of the PCR surveillance (b).	./cache/cord-336453-cbq0ui4p.txt	./txt/cord-336453-cbq0ui4p.txt
