Abstract
Background: Fipronil systemic insecticide and integrated vector management (IVM) leading to control and/or reduction of zoonotic cutaneous leishmaniasis (ZCL) cases were evaluated in the studied endemic foci of Fars province, southern Iran, during 2016 to 2017. Methods: Based on available data on disease circumstances collected from Center for Disease Control (CDC) of Shiraz University of Medical Sciences, incidence of disease, and demographics of the natives, five villages were randomly selected among those with high and medium CL infection in Kharameh area. All villagers were checked by physical examination and the incidence rates of ZCL cases were recorded. IVM interventions were implemented. Indeed, these procedures consisted of fipronil systemic insecticide poison baits, indoor residual spraying (IRS), outdoor spraying of the patients’ houses, and the thermal fogging (three times) during peak periods of sand flies’ activities. Results: After interventions, the incidence rates of ZCL decreased by 2.55% in Mehrabad village, in which all IVM methods were implemented. Similarly, the incidence of disease was reduced by 4.89% in Sofla and Moezabad villages, using exclusively fipronil poison baits. Besides, these incidence rates declined by 1.15% in two control villages of Soltan-Shahr and Abshor, where examination of the rodent reservoir hosts was performed. Conclusion: Fipronil and IVM methods were advantageous in reducing the incidence rates of leishmaniasis, but it seems that the use of fipronil systemic insecticide as a poison bait against reservoir rodent was significantly more effective (P-Value=0.01).

背景:对2016 - 2017年伊朗南部法尔斯省人畜共患皮肤利什曼病(ZCL)流行疫源地采用氟虫腈系统杀虫剂和媒介综合管理(IVM)控制和/或减少ZCL病例进行了评估。方法:根据设拉子医科大学疾病控制中心收集的疾病情况、发病率和当地人口统计资料,在卡拉梅地区CL高、中感染人群中随机抽取5个村庄。对所有村民进行体格检查,并记录ZCL病例的发病率。实施了IVM干预措施。实际上,这些程序包括氟虫腈系统杀虫剂毒饵,室内残留喷洒(IRS),患者房屋室外喷洒,以及在白蛉活动高峰期进行三次热雾化。结果:干预后,Mehrabad村所有IVM方法的ZCL发病率下降了2.55%。同样,使用氟虫腈毒饵后,Sofla和Moezabad村的发病率降低了4.89%。此外,在对鼠类宿主进行检查的两个对照村(Soltan-Shahr和Abshor),发病率下降了1.15%。结论:氟虫腈和IVM方法在降低利什曼病发病率方面均有优势,但用氟虫腈系统杀虫剂作为毒饵对水库鼠害效果更显著(p值=0.01)。Saki E, Soltani A, Djafar Moemenbellah-Fard M, Kalantari M, Dorzaban H, Azizi K. 2016 - 2017年伊朗南部法尔斯省人畜共患皮肤利什曼病病媒生物综合防治效果比较。卫生科学监测学报,2018;6(1):2-7。
