BACKGROUND: The coronavirus disease 2019 (COVID-19) outbreak has seriously
endangered the health and lives of Chinese people. In this study, we predicted
the COVID-19 epidemic trend and estimated the efficacy of several intervention
strategies in the mainland of China. METHODS: According to the COVID-19 epidemic
status, we constructed a compartmental model. Based on reported data from the
National Health Commission of People's Republic of China during January
10-February 17, 2020, we estimated the model parameters. We then predicted the
epidemic trend and transmission risk of COVID-19. Using a sensitivity analysis
method, we estimated the efficacy of several intervention strategies. RESULTS:
The cumulative number of confirmed cases in the mainland of China will be 86?763
(95% CI: 86 067-87?460) on May 2, 2020. Up until March 15, 2020, the case
fatality rate increased to 6.42% (95% CI: 6.16-6.68%). On February 23, 2020, the
existing confirmed cases reached its peak, with 60?890 cases (95% CI:
60 350-61?431). On January 23, 2020, the effective reproduction number was 2.620
(95% CI: 2.567-2.676) and had dropped below 1.0 since February 5, 2020. Due to
governmental intervention, the total number of confirmed cases was reduced by
99.85% on May 2, 2020. Had the isolation been relaxed from February 24, 2020,
there might have been a second peak of infection. However, relaxing the isolation
after March 16, 2020 greatly reduced the number of existing confirmed cases and
deaths. The total number of confirmed cases and deaths would increase by 8.72 and
9.44%, respectively, due to a 1-day delayed diagnosis in non-isolated infected
patients. Moreover, if the coverage of close contact tracing was increased to
100%, the cumulative number of confirmed cases would be decreased by 88.26% on
May 2, 2020. CONCLUSIONS: The quarantine measures adopted by the Chinese
government since January 23, 2020 were necessary and effective. Postponing the
relaxation of isolation, early diagnosis, patient isolation, broad close-contact
tracing, and strict monitoring of infected persons could effectively control the
COVID-19 epidemic. April 1, 2020 would be a reasonable date to lift quarantine in
Hubei and Wuhan.
