Objective To analyze the risk factors for severe illness caused by coronavirus disease 2019 in Fuzhou city. Methods The data of 4081 confirmed cases with current address in Fuzhou was collected from China Information System for Disease Control and Prevention from January 1 to June 30, 2023. The epidemiological data of those cases was investigated such as the demographic characteristics, clinical manifestations and past medical history, etc. The risk factors of severe cases were analyzed by using the logistic regression. Results 4081 confirmed cases had been reported including 671 severe cases and 3410 non-severe cases. The demographic characteristics of severe cases, such as the proportion of male, age and current address in community were higher than that of non-severe cases, vaccination rate was lower than non-severe cases (59.02% vs. 80.12%), the differences are statistically significant (P<0.001). The clinical manifestations such as interval time between onset and visit (P=0.001), fever (P=0.002), difficulty in breathing/shortness of breath (P=0.001) were the factors related to severe illness. The past medical histories such as history of chronic lung disease, history of heart cerebrovascular disease of severe cases, were higher than that of non-severe cases (P<0.001). Multivariate logistic regression showed that the male, the higher age, current address in community, no vaccination, the longer interval time between onset and visit, fever, difficulty in breathing/shortness of breath, the history of chronic lung disease, the history of heart cerebrovascular disease raised the risk of becoming severe cases. The healing time for severe cases was longer than that for non-severe cases (P<0.001). Conclusion Sex, age, current address, vaccination, interval time between onset and visit, fever, difficulty in breathing/shortness of breath, history of chronic lung disease, and history of heart cerebrovascular disease are the influencing factors for severe illness.
