摘　　要：目的 了解“6.1”地震灾后芦山县血吸虫病流行因素变化及传播风险,为指导震后血吸虫病防治提供科学依据。方法 根据芦山县血吸虫病历史疫情和2022年“6.1”地震破坏情况选取芦山县血吸虫病疫区村,于震后40 d收集地震危害和血防历史资料,开展血吸虫病传染源、中间宿主钉螺及相关流行因素调查。结果 共调查芦山县太平镇胜利村、龙门镇古城村和芦阳街道灵鹫山社区3个村的钉螺面积116.4万m2,发现有螺环境7处,有螺面积19.3万m2,捕获钉螺191只,未发现感染性钉螺;人群血清学筛查1 234人,血检阳性37人,阳性率3.00%,粪检未发现血吸虫病人;检查犬只60头,未发现血吸虫病犬;检获动物野粪3份,未发现阳性野粪。地震引起的血吸虫病流行相关因素的变化相对较小。结论 “6.1”芦山地震未明显增加当地血吸虫病传播风险。为确保震后无大疫,应加强血吸虫病传染源控制、钉螺控制、疫情监测等。Objective To understand the change of prevalence factors and the transmission risk of schistosomiasis after the"6.1"earthquake in Lushan County,and to provide scientific basis for schistosomiasis prevention and control after the earthquake.Methods Villages suffered from schistosomiasis epidemic in Lushan County were selected according to the historical prevalence of schistosomiasis and the damage caused by the"6.1"earthquake in 2022.The historical data of S schistosomiasis control and earthquake hazards were collected 40 days after the earthquake.Source ofinfection,intermediate host snails and related epidemic factors of schistosomiasis were investigated.Results The snail 1 area of Shengli Village of Taiping Town,Gucheng Village of Longmen Town and Lingjiushan Village of Luyang Street was investigated by a total of 1.164 million m^(2).There were 7 snail-infested environments,with an area of 193000 m^(2).A total of 191 snails were captured and no infectious snails were found.A total of 1234 people were serologically screened,and 37 people were found to be positive,with a positive rate of 3.00%.No schistosomiasis was found in fecal examination.A total of 60 dogsswereexamined and no schistosomiasis was found.Three samples of wild animal feces were seized and no positive feces were found.The factors associated with the prevalence of schistosomiasis caused by the earthquake had changed slightly.Conclusions The"6.1"earthquake in Lushan County did not significantly increase the risk of local schistosomiasis transmission.In order to ensure that there is no major epidemic after the earthquake,it is necessary to strengthen the infection source control,snail control and epidemic surveillance of schistosomiasis.
