Abstract: Clinical data of 150 patients with mild and 38 patients with severe confirmed influenza A/H1N1 were collected and retrospectively analyzed in this paper with descriptive epidemiology. Mild patients mainly presented with symptoms similar to seasonal influenza with few complications, however,persistent high fever, cough with bloody sputum expectoration, chest distress and short of breath manifested in severe patients with respiratory failure and acute respiratory distress syndrome in some cases. Proportion of obesity and underlying diseases in severe patients, who were at high risk for severe influenza A/H1N1, was higher than that in mild ones (P＜0. 05). Average course of the illness spanned five to 11 days in patient with mild influenza A/H1N1 with all cured, and 34 of severe cases discharged with better recovery and other four died with a case-fatality of 10. 5 percent.
