近 10多年来 ,先后从云南省景洪市各乡镇的当地病人、猪、蝙蝠和蚊虫体内分离出乙型脑炎病毒 2 2株 ,从白纹伊蚊中分离到登革 4型病毒 1株 ,从蝙蝠和蚊虫体内分离到基孔肯雅病毒 5株 ,从患者急性期血液中分离到辛德毕斯病毒1株 ,从发热病人血液、脑炎病人脑脊液、猪血清和牛血清中分离到新环状病毒 47株 ,从黄胸鼠肺脏中检查出流行性出血热病毒抗原阳性 6份 ;人群、猪、恒河猴或鼠类血清中亦检出上述 6种病毒的抗体 ,表明景洪市存在乙型脑炎、登革热、基孔肯雅、辛德毕斯、新环状病毒和流行性出血热自然疫源地。此外 ,该地人群血清中还检查出西门利克森林病 (SF)、格塔 (GET)、库京 (KUN)、圣路易脑炎 (SL E)、雪鞋野兔 (SSH)、巴泰 (BAT)、森林脑炎 (RSSE)、柯萨努尔森林病 (KFD)、波瓦生 (POW)、兰格特 (L GT)和克里米亚 -刚果出血热 (CCHF)等多种病毒抗体 ,提示当地可能存在更多的蚊媒和蜱媒病毒。
