Objective To analyze the epidemiological characteristics of coronavirus disease 2019 (COVID-19) cases in Jingzhou, Hubei, and provide scientific basis for the prevention and control of similar epidemic in future.
Methods We collected COVID-19 cases information reported in Jingzhou in 2020 from China Disease Prevention and Control Information System, and described the cases’ temporal-spatial distribution, population distribution and other epidemiological characteristics.
Results A total of 1 550 COVID-19 cases were reported in Jingzhou in 2020. The proportion of severe case was 22.71% (352/1 550) and the case fatality rate was 3.29% (51/1 550). Among these cases, 49.61% (769/1 550) cases reported clear sojourn history in Wuhan within 14 days before the onset. The first case was reported on January 1, 2020. The incidence peak occurred during January 23–28, 2020. The last case was reported on February 26, 2020. Most cases were in age group 50–59 years (23.23%, 360/1 550). The cases were distributed in 92.91% (118/127) of townships (streets). The risk of death in age group ≥60 years was 10.53 times than that in age group <60 years (95% CI: 4.70–23.60), and the risk of death in people with underlying medical conditions was 1.95 times (95% CI: 1.05–3.61) than that in previous healthy people. The interval from onset to report (median: 7.8 days) in the first stage from January 1 to January 31 was longer than that (median: 3.5 days) in the second stage from February 1 to February 26 (P<0.001).
Conclusion Most COVID-19 cases in Jingzhou had exposures in Wuhan. The proportion of severe cases was not high, and most townships were affected. The case fatality was high in people with underlying medical conditions and elderly persons. The prevention and control strategy of ‘early detection’ was better implemented in the second stage than in the first stage. People with multiple underlying diseases and the elderly were with a higher case fatality rate.
