摘　　要：目的了解合肥市健康人群发热伴血小板减少综合征病毒(SFTSV)的感染现状,分析在生活环境和户外劳作中成人感染的危险因素,为科学防控提供依据。方法通过空间简单随机抽样法采集865名健康人群血样检测SFTSV-IgG,问卷调查709名成人,多因素logistic回归分析成人生活环境和户外劳作中感染的危险因素。结果合肥市健康人群SFTSV-IgG为6.71%。主城区和县(市)、9个县(市、区)间和抽取的乡镇间的阳性率差异均无统计学意义(χ2=0.005,P=0.945;χ2=3.662,P=0.886;χ2=31.987,P=0.614),男女阳性率分别为6.68%和6.73%,性别间阳性率差异无统计学意义(χ2=0.001,P=0.979);<20岁人群阳性率最高(8.95%),不同年龄组阳性率差异无统计学意义(χ2=2.545,P=0.467);幼托儿童和学生阳性率分别11.76%和8.59%,均高于其他职业人群,但差异无统计学意义(χ2=4.065,P=0.896)。居住在村/小区中间,经常采茶,饲养附着蜱的家禽家畜,接触野生动物是成人感染SFTSV的危险因素。结论合肥市健康人群SFTSV-IgG阳性率较高,阳性率在人口学特征方面无统计学差异,人群普遍易感。生活环境和户外劳作中的居住在村/小区中间,经常采茶,饲养附着蜱的家禽家畜,接触野生动物是危险因素。Objective The aim of this study was to investigate the infection status of severe fever with thrombocytopenia syndrome virus(SFTSV)in healthy crowds of Hefei,analyze risk factors of adult infection in living environment and outdoor work,so as to provide the basis for scientific prevention and control.Methods 856 blood samples in healthy crowds were collected by spatial simple random sampling and detected by SFTSV-IgG.709 healthy adults were investigated,and the risk factors of infection in living environment and outdoor work were analyzed with multiple logistic regression.Results The positive rate of SFTSV-IgG was 6.71%.There was no statistical significant difference in the main urban area and counties of Hefei,9 counties of Hefei and selected towns(χ2=0.005,P=0.945;χ2=3.662,P=0.886 andχ2=31.987,P=0.61).Men and women’s positive rate were 6.68%and 6.73%,respectively.There was no statistical significant difference in different gender for the positive rate(χ2=0.001,P=0.979).The positive rate was the highest under 20 years old(8.95%).There was no statistical significant difference in different age groups for the positive rate(χ2=2.545,P=0.467).The positive rate in nursery children and students were 11.76%and 8.59%,respectively,higher than other occupation populations,but there was no statistically significant difference(χ2=4.065,P=0.896).Living in the middle of village/residential districts,often tea picking,raising domestic animals with ticks and contact with wild animals were risk factors of adult infection.Conclusion The positive rate of SFTSV-IgG among healthy people was relatively high in Hefei.The positive rate by demographic characteristics showed no statistical differences.People were generally susceptible.Living in the middle of village/residential districts,often tea picking,raising domestic animals with ticks and contact with wild animals in living environment and outdoor work were risk factors.
