A total of 3499 cases of influenza A (H1N1) were included in this study for analysis.Epidemiological and clinical data of these cases were input into EpiData software and analyzed by SPSS software. Throat swabs were collected from the cases and detected for nucleic acid of influenza A ( H1N1 )virus using real-time polymerase chain reaction (RT-PCR) with fluorescence quantitative method, and time of viral excretion and clinical features of the cases were analyzed. Results showed that 0. 37% of the cases were in-apparent and asymptomatic and the most common symptom of the cases was fever (86. 77% ).Throat swabs converted to negative on the sixth day of onset in average, and no factors related to the time of conversion was found with logistic regression analysis.
