Objective: To investigate the epidemiological characteristics of Corona Virus Disease 2019 (COVID-19) and analyze the influencing factors of the critically ill patients Methods: The data of 55 patients with con-firmed COVID-19 who were treated in Sanya Central Hospital ( The Third People' s Hospital of Hainan Province were retrospectively investigated, the distribution of the infection in different populations, areas and time periods was observed, and the influencing factors of the critically ill patients were explored Results: Among the 55 patients with confirmed COVID-19, 20 (36 4%) were male, and 35 (63 6%) were female;32 (58 2%) were more than 50 years old As for the clinical classifications, there were 34 (61 8%) patients with common type and 21(38 2%) patients with severe, critically severe type 60 0% of the confirmed cases had the history of exposure to Wuhan before the onset, and 30 9% were infected through contact with family members Totally 53 cases were cured and discharged, with the cure rate 96 4%;2 cases died, with the mortality rate 3 6% There was no significant difference in the distribution of gender between the patients with severe, critically severe COVID-19 and the patients with the common type The incidence of severe, critically severe COVID-19 was associated with the no less than 50 years of age, latent period no less than 7 days , delayed treatment, poor living condition, personal protection measures, underlying disease and clinical symptoms such as fatigue complicated with chest distress (P <0 05) Conclusion: The history of exposure to Wuhan is the leading cause of second generation of recurrent case The influencing factors for the severe COVID-19 include the no less than 50 years of age, latent period no less than7 days, delayed treatment, poor living condition, poor personal protection, underlying disease and clinical symptoms such as fatigue complicated with chest distress It is necessary to take effective protection measures aiming at the influencing factors as early as possible so as to reduce the risk of severe COVID-19
