Objective To investigate the epidemiology and clinical features of imported dengue fever. Methods A retrospective analysis was performed on the data of 16 imported dengue patients admitted to our hospital from 2008 to 2013. Results Of the 16 patients, 11 were males, with an average age of 30.9 years and 6.0 years. Nine of the 16 patients were foreign-related employees. Sixteen patients were imported into Southeast Asian countries. The incidence of 16 patients was from May to September. The average time between onset and diagnosis was 4.7 days. The main clinical manifestations included fever (100.00%), rash (75.00%), headache (62.50%), muscle soreness (62.50%), fatigue (50.00%) and facial flushing (50.00%). Abnormal laboratory tests included leukopenia (87.50%), thrombocytopenia (75.00%), elevated creatine kinase (50.00%), and decreased serum potassium (37.50%). The average length of stay was 6.4 days ± 2.0 days. Conclusion The imported dengue fever is mainly young and middle-aged, with obvious seasonal and mostly typical clinical manifestations. The main complications are liver injury and hypokalemia.
