The results from kernel ratios showed that peripheral census tracts were the most heavily affected. Local spatial analysis showed that in the beginning of the study period local clusters of high incidence of VL were mostly located in the southern and northeastern parts of the city, but in subsequent years those clusters also appeared in the northern region of the city, suggesting that the pattern of VL is not static, and the disease may occasionally spread to other areas of the municipality. We also observed a spatial correlation between VL rates and all socioeconomic and demographic indicators evaluated (<jats:italic>P<\/jats:italic> &lt; 0.01). The concentration of interventions in high-risk areas could be an effective strategy to control the disease in the urban setting.<\/jats:p>","DOI":"10.4269\/ajtmh.2011.10-0325","type":"journal-article","created":{"date-parts":[[2011,5,3]],"date-time":"2011-05-03T18:53:58Z","timestamp":1304448838000},"page":"681-687","source":"Crossref","is-referenced-by-count":37,"title":["Identification of Risk Areas for Visceral Leishmaniasis in Teresina, Piaui State, Brazil"],"prefix":"10.4269","volume":"84","author":[{"given":"Andr\u00e9a S.","family":"de Almeida","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"de Andrade Medronho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guilherme L.","family":"Werneck","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2795","reference":[{"key":"R1","series-title":"Rev Soc Bras Med Trop","first-page":"227","article-title":"Expans\u00e3o espacial da leishmaniose visceral americana em S\u00e3o Luis, Maranh\u00e3o, Brasil","volume":"35","author":"Mendes","year":"2000"},{"key":"R2","series-title":"Acta Trop","first-page":"13","article-title":"The burden of Leishmania chagasi infection during an urban outbreak of visceral leishmaniasis in Brazil","volume":"83","author":"Werneck","year":"2002"},{"key":"R3","series-title":"Epidemiol Serv Sa\u00fade","first-page":"143","article-title":"Utiliza\u00e7\u00e3o de dados censit\u00e1rios em substitui\u00e7\u00e3o a informa\u00e7\u00f5es socioecon\u00f4micas obtidas no n\u00edvel individual: uma avalia\u00e7\u00e3o emp\u00edrica","volume":"14","author":"Werneck","year":"2005"},{"key":"R4","series-title":"Rev Soc Bras Med Trop","first-page":"446","article-title":"Foco emergente de leishmaniose visceral em Mato Grosso do Sul","volume":"39","author":"Oliveira","year":"2006"},{"key":"R5","series-title":"Rev Soc Bras Med Trop","first-page":"352","article-title":"Expans\u00e3o geogr\u00e1fica da leishmaniose visceral no Estado de Pernambuco","volume":"39","author":"Dantas-Torres","year":"2006"},{"key":"R6","series-title":"Cad Saude Publica","first-page":"2959","article-title":"Characterization and speculations on the urbanization of visceral leishmaniasis in Brazil","volume":"24","author":"Costa","year":"2008"},{"key":"R7","series-title":"Rev Bras Epidemiol","first-page":"338","article-title":"Leishmaniose visceral no Brasil: quadro atual, desafios e perspectivas","volume":"7","author":"Gontijo","year":"2004"},{"key":"R8","series-title":"Rev Saude Publica","first-page":"361","article-title":"Epidemia de leishmaniose visceral no estado do Piau\u00ed, Brasil, 1980\u20131986","volume":"24","author":"Costa","year":"1990"},{"key":"R9","series-title":"Teresina: Aspectos e Caracter\u00edsticas","author":"Teresina","year":"1993"},{"key":"R10","series-title":"Tropical and Geographical Medicine","first-page":"146","author":"Spielman","year":"1990"},{"key":"R11","series-title":"Cad Saude Publica","first-page":"2948","article-title":"Lutzomyia longipalpis (Diptera, Psychodidae, Phlebotominae) and urbanization of visceral leishmaniasis in Brazil","volume":"24","author":"Rangel","year":"2008"},{"key":"R12","series-title":"Cad Saude Publica","first-page":"2937","article-title":"Forum: geographic spread and urbanization of visceral leishmaniasis in Brazil.
