The typically rural disease began to appear in urban areas over time, being concentrated mainly in Teresina, the capital of Piau\u00ed. Teresina was also affected by the first urban epidemic of VL in Brazil. Over 1,000 cases of the disease were reported during urbanization (1981-1986). Human population growth and migration led to land occupation on the outskirts of Teresina. These factors have contributed to vector proliferation, increasing the incidence of VL. At present, the incidence of human and canine disease is quite high and uncontrolled in Piau\u00ed. It seems that some measures, such as the elimination of seropositive dogs, failed to significantly reduce the number of new VL cases in Teresina. Despite previously conducted studies, little is known about VL epidemiology in urban areas. The aim of this review is to reveal the situation of VL in Teresina during the last 40 years, focusing on the major factors that may contribute to the high incidence and persistence of VL infection.<\/jats:p>","DOI":"10.1590\/s0036-46652011000100002","type":"journal-article","created":{"date-parts":[[2011,3,7]],"date-time":"2011-03-07T14:16:59Z","timestamp":1299507419000},"page":"3-11","source":"Crossref","is-referenced-by-count":15,"title":["Forty years of visceral leishmaniasis in the State of Piaui: a review"],"prefix":"10.1590","volume":"53","author":[{"given":"Karina Oliveira","family":"Drumond","sequence":"first","affiliation":[{"name":"Universidade Federal do Piau\u00ed,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco Assis Lima","family":"Costa","sequence":"additional","affiliation":[{"name":"UFPI"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"195","DOI":"10.1590\/S0102-311X1996000200008","article-title":"Ecologia dos flebotom\u00edneos da Serra do Mar, Itagua\u00ed, Estado do Rio de Janeiro, Brasil: I -
