Zoonotic visceral leishmaniasis (ZVL), caused by protozoans of the genus Leishmania, it is a worldwide of great importance disease. In the northeast region of Brazil, the state of Alagoas has an endemic status for ZVL. Thus, this work aimed to analyze the epidemiological situation of human and canine visceral leishmaniasis in Alagoas, Northeast, Brazil, from 2007 to 2013. We conducted a descriptive, observational, retrospective study using secondary data from the Notifiable Diseases Information System, the Center of Zoonosis Control of Maceió, and the Central Laboratory of Public Health of Alagoas. During the studied period, it was observed that the highest incidence of human visceral leishmaniasis was in 2011 and the lowest in 2013. On the other hand, canine visceral leishmaniasis had its highest incidence in 2007 and its lowest in 2012. Of the 55 municipalities in the State of Alagoas that showed human visceral leishmaniasis (HVL), São José da Tapera presented an average of 4.4 cases over the past five years, being classified as of intense transmission. Regarding canine visceral leishmaniasis, in the same studied period, 45,112 dogs were examined in the State, of which 4,466 were positive. It resulted, thus, in a 9.9% positivity rate.
Our data are important because canine infection is an important risk factor for the human disease.
人兽共患内脏利什曼病（ZVL）由利什曼原虫属的原生动物引起，是一种在全球具有重大意义的疾病。在巴西东北部地区，阿拉戈斯州是ZVL的地方病流行区。因此，本研究旨在分析2007年至2013年巴西东北部阿拉戈斯州人类和犬类内脏利什曼病的流行病学情况。我们使用法定传染病信息系统、马塞约人畜共患病控制中心和阿拉戈斯州公共卫生中央实验室的二手数据进行了一项描述性、观察性、回顾性研究。在研究期间，观察到人类内脏利什曼病的发病率在2011年最高，在2013年最低。另一方面，犬类内脏利什曼病的发病率在2007年最高，在2012年最低。在阿拉戈斯州出现人类内脏利什曼病（HVL）的55个市中，圣若泽 - 达塔佩拉在过去五年中平均有4.4例病例，被归类为高强度传播地区。关于犬类内脏利什曼病，在同一研究期间，该州共检查了45112只狗，其中4466只为阳性。因此，阳性率为9.9%。
我们的数据很重要，因为犬类感染是人类疾病的一个重要风险因素。
