The transmission of tegumentary leishmaniasis (TL) has increased in 9 provinces of Argentina since 1985. Santa Fe and Entre Ríos did not record in this period autochtonous probed cases: however, an epidemic outbreak took place in 2003 in Bella Vista, Corrientes, located in an area with ecological continuity and contiguous to both provinces. In order to evaluate the potential risk of transmission of LT, Phlebotominae were captured at locations close to and southern from Bella Vista during February 2004. The traps located on the shores of Parana river in Santa Fe (El Rabón, Villa Ocampo, Cayastá), and Entre Ríos (La Paz. La Celina-Villa Urquiza) captured 860 individuals of Lutzomyia neivai (99.5%) and Lu. migonei (0.5 %), both species with vectorial capacity for Leishmania (V.) braziliensis. In Tartagal, Santa Fe, the captures were consistent with the residual "chaco" landscape, 7 individuals of Lu. nerivai, Lu. migonei and Lu. cortelezzii. The risk of LT epidemic transmission in these provinces is highlighted, mainly due to the progressive southern tropicalization of the paranaense gallery forest. Clinical and entomological surveillance is recommended.
自1985年以来，阿根廷9个省份的皮肤利什曼病（TL）传播有所增加。在此期间，圣菲省和恩特雷里奥斯省未记录到本地确诊病例：然而，2003年在科连特斯省贝拉维斯塔发生了一次疫情爆发，该地区生态环境具有连续性，且与这两个省份接壤。为了评估利什曼病传播的潜在风险，2004年2月在贝拉维斯塔附近及以南地区捕获了白蛉。位于圣菲省巴拉那河岸（埃尔拉本、奥坎波别墅、卡亚斯塔）和恩特雷里奥斯省（拉巴斯、拉塞利纳 - 乌尔基萨别墅）的诱捕器捕获了860只内氏罗蛉（99.5%）和米氏罗蛉（0.5%），这两个物种都具有传播巴西利什曼原虫的媒介能力。在圣菲省的塔尔塔加尔，捕获情况与残留的“查科”景观一致，捕获到7只内氏罗蛉、米氏罗蛉和科氏罗蛉。这些省份利什曼病疫情传播的风险凸显出来，主要是由于巴拉那河沿岸森林逐渐向南热带化。建议进行临床和昆虫学监测。
