Visceral leishmaniasis (VL) is caused by Leishmania (L.) infantum chagasi in the Americas. In Brazil, it is transmitted by sandflies of the species Lutzomyia longipalpis and L. cruzi, and dogs are the main domestic reservoirs. The aim of this study was to analyze data relating to VL transmission in Jaciara, state of Mato Grosso, and discuss vector distribution, domestic reservoirs, and human cases that occurred between 2003 and 2012. The data for analysis were obtained from the Notifiable Diseases Information System (human), the State Health Department's Environmental Monitoring Agency (canine data) and the State Health Department's Entomology Laboratory (sandfly data). Over this period, Jaciara had 19 autochthonous human cases (12 males and seven females), with one death 2,273. Out of the 7,545 dogs tested by enzyme immunoassay and indirect immunofluorescence were positive. The sandflies collected comprised 5,015 individuals belonging to 24 species, with a predominance of L. whitmani followed by L. cruzi. The results showed that the parasite has frequent circulation and that the vector L. cruzi is widely distributed over all months, thus suggesting that transmission may occur at any time of the year.
美洲内脏利什曼病（VL）由婴儿利什曼原虫恰加斯亚种引起。在巴西，它由长须罗蛉和克鲁兹罗蛉传播，狗是主要的家养宿主。本研究的目的是分析与马托格罗索州贾西亚拉市VL传播相关的数据，并讨论2003年至2012年间的病媒分布、家养宿主和人类病例。分析数据来自法定传染病信息系统（人类）、州卫生部环境监测机构（犬类数据）和州卫生部昆虫学实验室（白蛉数据）。在此期间，贾西亚拉市有19例本地人类病例（12名男性和7名女性），1例死亡。在通过酶免疫测定和间接免疫荧光检测的7545只狗中，呈阳性。采集的白蛉包括属于24个物种的5015只个体，以惠特曼罗蛉为主，其次是克鲁兹罗蛉。结果表明，该寄生虫频繁传播，病媒克鲁兹罗蛉全年广泛分布，因此表明传播可能在一年中的任何时候发生。
