Objectives: To compare the clinical characteristics and the dynamics of viral load between imported and non-imported patients with COVID-19. Design and methods: Data from 51 laboratory-confirmed patients were retrospectively analyzed. Results: The incubation period in the tertiary group was longer than that in the imported and secondary groups (both p 0.05). For the tertiary group, the viral load was undetectable in half of the patients (52.63%) on day 7, and in all patients on day 14. For one third of the patients in the imported and secondary groups, the viral load remained positive on day 14 after the admission. Conclusions: COVID-19 can present as pneumonia with a low onset of symptoms, and the infectivity of SARS-CoV2 may gradually decrease in tertiary patients.
