to describe operational difficulties in the implementation of deltamethrin-impregnated dog collars for the control of visceral leishmaniasis.
this was a community intervention trial in the municipality of Montes Claros, MG, Brazil, comparing (i) control area - dogs without dog collars - and (ii) intervention area - use of 4% deltamethrin-impregnated collars; an initial serological survey was performed, followed by three further cycles (at 12, 18 and 24 months).
out of 4,388 dogs initially seronegative wearing collars, 36.9% were not found in the second cycle, 27.0% of them were lost owing to disappearance/given away/sale, and 22.6% because no one was at home; 56.1% of collars were lost in one year; while among dogs that stayed longer in the study, collar loss was lower.
high frequencies of collar loss and no one being at home at the time of the visit are operational difficulties for the implementation of a national control program based on the strategy evaluated.
描述在使用含溴氰菊酯的犬项圈控制内脏利什曼病过程中遇到的操作困难。
这是在巴西米纳斯吉拉斯州蒙特斯克拉罗斯市进行的一项社区干预试验，比较了（i）对照区域——未佩戴犬项圈的犬只——和（ii）干预区域——使用含4%溴氰菊酯的项圈；进行了一次初始血清学调查，随后又进行了三个周期（分别在12、18和24个月时）的调查。
在最初4388只血清学检测呈阴性且佩戴项圈的犬只中，在第二个周期有36.9%未被找到，其中27.0%是因为失踪/被送人/被卖掉，22.6%是因为家中无人；一年中有56.1%的项圈丢失；而在研究中停留时间较长的犬只中，项圈丢失率较低。
项圈丢失率高以及在访视时家中无人是基于所评估策略实施全国性控制项目时遇到的操作困难。
