摘要
目的了解玉溪市人群Ev71病毒感染状况，为防制手足口病提供科学依据。方法采用容量比例概率抽样法（PPS法）对玉溪市峨山、新平县6个乡镇18个行政村人群按年龄分配随机调查。并对调查人群采集静脉血液标本进行EV71抗体检测。结果共调查788人，EV71病毒抗体（EV71-IgG）阳性率为41．37％，不同年龄组Ev71-IgG抗体阳性率差异有统计学意义（x2=42．24，P〈0．05），其中5-6岁人群阳性率最高为64．00％，〈1岁婴儿阳性率最低为20．65％；不同民族EV71-IgG抗体阳性率有显著差异（x2=13．89，P〈0．05），彝族相对较高为46．67％，哈尼族最低为21．11％；性别间阳性率差异有统计学意义（X2=5．63，P〈0．05），女性高于男性。结论玉溪市人群对手足口（EV71）病原普遍易感，做好人群手足口病防制仍然是今后的工作重点。
Objective To investigate the infection status of EVT1 and to provide references for prevention and control of hand - foot - mouth disease （HFMD）. Methods With Probability - proportional - to - size sam- pling method, residents in 18 administrative villages of 6 townships in Eshan and Xinping county were ran- domly surveyed according to the age distribution. The participants＇ blood samples were collected and were tested EV71 antibody. Results A total of 788 individuals were investigated, with the positive rate of EV71 antibody （ EV71 - IgG） as 41.37%. The positive rate among different age groups showed statistical differ- ence （ X 2 = 42. 24, P 〈 0. 05 ）, with 5 - 6 years old group as the highest （64%） and 〈 1 year old group as the lowest （20. 65% ）. The positive rate demonstrated statistical difference among ethnics （X2 = 13.89, P 〈0. 05）, with Yi as the highest （46.67%） and Hani as the lowest （21.11%）. Higher positive rate was founded in female than in male. Conclusion At large, the population in Yuxi tends to be vulnerable to EV71. The prevention and control of HFMD is still the focus.
