目的了解黔南及黔东南部分虫媒病毒人群血清抗体阳性分布。方法 2012年8月,选取在当地连续居住1年以上、年龄18~40岁的自愿健康人群,用间接免疫荧光试验法,调查马亚罗(MAY)、辛德比斯(SIN)、基孔肯雅(CHIK)、盖他(GET)、流行性乙型脑炎(JE)、登革热Ⅲ型(DEN-3)、流行性出血热(EHF)和森林脑炎(TBE)病毒在黔南及黔东南人群中的阳性分布。结果共检测血清标本502份,111份至少有1种病毒抗体阳性,抗体阳性检出率最高的是JE,阳性率为12.15%;其次为MAY,阳性率为10.28%;TBE未检出抗体阳性血清。居住时间、居住地性质和地区分布对抗体的阳性分布影响较为显著。结论黔南和黔东南可能是多种虫媒病毒病的自然疫源地。
Objective To understand the positive distribution of serum antibody of some arbovirus in southern Guizhou and southeast Guizhou. Methods In August 2012, the volunteers, who were continuously living in the area for more than one year and were 18 to 40 years old, were selected for the study. By indirect immunofluorescence assay, MAY, SIN, CHIK, GET, JE, DEN-3, EHF and TBE viruses in Qiannan and Qian The positive distribution in Southeast China. Results A total of 502 serum samples were detected, of which 111 were positive for at least one virus antibody. The positive rate of JE was 12.15%, followed by MAY with a positive rate of 10.28%. TBE did not detect any antibody positive serum. Living time, the nature of the place of residence and the distribution of the distribution of the positive impact of antibodies is more significant. Conclusion Qiannan and Qiandongnan may be natural foci of various arboviral viruses.
