Investigation of Hospitalized Patients with New Influenza A(H1N1) in Hangzhou

[目的]研究杭州地区新型甲型H1N1流感的临床表现和流行病学特点。[方法]用统计指标和图表来描述杭州地区104例新型甲型H1N1流感住院病例的临床表现和血液化验数据,比较各年龄组和不同时间段组的新型甲型H1N1流感的临床表现。[结果]在104例病例中20岁及20岁以下的人群占57.7%。20岁及20岁以下与20岁以上的新型甲型H1N1流感病人的病程长短和白细胞计数的差异没有统计学意义(P>0.05),不同时期发病的新型甲型H1N1流感病人的病程长短和白细胞计数的差异没有统计学意义(P>0.05)。[结论]杭州地区的新型甲型H1N1流感青少年、学生较多,65岁以上老年人较少;重症和死亡病人较少,咳嗽是新型甲型H1N1流感的主要症状,各年龄层次新型甲型H1N1流感的临床表现差异不大。

[Objective] To study the clinical and epidemiological characteristics of new influenza A(H1N1).[Methods] We described the clinical manifestation and the data of blood test of 104 patients who have caught New Influenza A(H1N1) with statistical indexes,tables and charts.And we contrasted the clinical manifestation of New Influenza A(H1N1) of the groups with different age and period.[Results] Of the 104 patients,57.7% were 20 years of age or younger,and nobody was 65 years of age or older.The differences of the duration and the leucocyte count of new influenza A(H1N1) between the age of 20 years or under it and 20 years older were not statistically significant(P>0.05);The differences of the duration and the leucocyte count of new infuenza A(H1N1) between two periods of morbidity were not statistically significant(P>0.05).[Conclusion] The majority of the patients catching new influenza A(H1N1) recently were adolescent or students;the minor were 65 years of age older;few patients were serious or died.Cough was the major symptom of new influenza A(H1N1).The differences of the clinical manifestation about new influenza A(H1N1) between different age levels were inapparent;the visible change of clinical manifestation from variations of new influenza A(H1N1) virus did not appear from June to September.
