摘　　要：[目的]了解山西省2005年流感流行情况,为我省流感流行的趋势和病毒变异的预测提供理论依据。[方法]采用微量血凝抑制实验对不同地区不同年龄组正常人群的393份血清标本进行检测。[结果]山西省2005年正常人群的总阳性率和几何平均滴度以B/沪/361/2002最高(95.9%,237.74),其次为A3/闽/411/2002(91.6%,65.76),A1/沪/7/1999最低(85.8%,59.64)。3个地区中山西省南部的临汾地区乙型抗体水平最高;甲3型抗体水平以中部的晋中地区为最低;北部的大同地区甲1型抗体水平高于另两地。不同年龄的人群中6￣岁人群的3型抗体水平均为最高。[结论]甲3型,甲1型流感在该省曾有过流行,但该省2004￣2005年流感流行以乙型为主。3型抗体的分布有地区和年龄的差异。[Objective] To understand the condition of influenza virus prevailing of Shanxi in 2005 and take theretic information for influenza prevailing prediction and influenza virus variance prediction in Shanxi. [Methods] The antibody liters of 393 healthy persons in different districts and different ages were detected by using hemagglutination inhibition test. [ Results] The positive rates and the geometricmean titers of B/shanghai/361/2002 （95.9%, 237.74） was the highest among the healthy population.The second was A3/fujian/411/2002 （91.6%, 65.76） . The lowest was A1/shanghai/7/1999 （85.8%, 59.64） . The antibody of B/shanghai/361/2002 in IAnfen and the A1/shanghai/7/1999 in Datong was the highest in three districts. The A3/fujian/411/2002 in Jinzhong was the lowest in the three districts. Three types antibodies of the 6- years old were all the highest in population. [Conclusions] A1/shanghai/7/1999, A3/fujian/411/2002 have prevailed in Shanxi Province, but B/ shanghai/361/2002 is preponderant strain in 2005, and the distrition of three types antibodies in different districts and ages is significantly different.
