Abstract: 〔Abstract〕Objective: To provide a theoretical basis for the early diagnosis, treatment, prevention and control of dengue fever based
on an analysis of the relevant data of imported dengue fever in Kunming City. Methods: Data were collected from patients with dengue
fever, the epidemiological characteristics were described, and the correlation between the course of disease and laboratory examination
indicators was analyzed. Results: There were a total of 143 patients with 101 males（70.63%）and 42 females（29.37%）, with an
average age of（34.72±9.79）years. Cases were reported from May to December. 91 patients（63.64%）were from Cambodia. The main
clinical manifestations were fever in 143 cases（100.00%）, muscle soreness in 123 cases（86.01%）, pharyngeal congestion in 109
cases（76.22%）, headache in 107 cases（74.83%）and fatigue in 88 cases（61.54%）. Laboratory results: 96 patients had leukopenia
（67.13%）, aspartate aminotransferase（AST）increased in 87 patients（60.84%）, and C-reactive protein（CRP）increased in 74
patients（51.75%）. The course of the disease was significantly correlated with white blood cells, platelets（PLT）, total bilirubin,
indirect bilirubin, gamma-glutamine transferase（GGT）and AST（P < 0.05）. Conclusion: Dengue fever in Kunming is mainly
imported from abroad and infected by common dengue fever. The course of the disease is positively correlated with total bilirubin,
indirect bilirubin, GGT and AST, but it is negatively correlated with white blood cells and PLT.
