To determine the prevalence of leptospirosis in patients from Veracruz with initial diagnosis of dengue and its association with risk factors.<jats:italic>Materials and Methods<\/jats:italic>. Transversal study in patients who sought medical attention under the suspicion of dengue. Backgrounds were researched and blood samples were drawn to determine dengue (NS1, RT-PCR) and leptospirosis (IFI). Simple frequencies, central tendency and dispersion measures, and prevalence and trust intervals at 95% (IC95%) were obtained. Prevalence reasons (RP) and IC<jats:sub>95%<\/jats:sub>were obtained and a multivariate logistic model was applied, using SPSS\u2009V15.<jats:italic>Results<\/jats:italic>. 171 patients were included, 56% women ( years) and 44% men ( years). 48% of the cases (IC95%\u200940.5\u201355.4) was positive to dengue, with a cut point of 1\u2009:\u200980, seroprevalence for leptospirosis was of 6% (IC<jats:sub>95%<\/jats:sub>\u20092.7\u201310); 12% (IC95%\u20097\u201316.5) was positive to both pathologies and 34% was negative to both tests. Although the largest number of isolations corresponded to serotype 2, the four dengue virus serotypes were identified. In the bivariate analysis, overcrowding RP\u2009=\u20091.33, (IC\u2009=\u20090.46\u20133.5), bathing in rivers (RP\u2009=\u20091.31, IC\u2009=\u20090.13\u20137.4), and walking barefoot (RP\u2009=\u20091.39, IC\u2009=\u20090.58\u20133.3) were the variables associated with leptospirosis, although the relation was not statistically significant.<jats:italic>Conclusions<\/jats:italic>. Leptospirosis prevalence in subjects under suspicion of dengue fever is high, as well as the coincidence of both infections. The results show the coexistence of overlapped outbreaks of several diseases sharing the side of transmission. It is necessary the intentional search of other pathologies, such as influenza, rickettsiosis, and brucella, among others.<\/jats:p>","DOI":"10.1155\/2012\/519701","type":"journal-article","created":{"date-parts":[[2012,4,25]],"date-time":"2012-04-25T00:15:54Z","timestamp":1335312954000},"page":"1-5","source":"Crossref","is-referenced-by-count":16,"title":["Leptospirosis Prevalence in Patients with Initial Diagnosis of Dengue"],"prefix":"10.1155","volume":"2012","author":[{"given":"A.","family":"Dircio Montes Sergio","sequence":"first","affiliation":[{"name":"Coordinaci\u00f3n de Vigilancia Epidemiol\u00f3gica y Apoyo en Contingencias, Unidad de Salud P\u00fablica, Instituto Mexicano del Seguro Social (IMSS), 03100, Mexico City, DF, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Gonz\u00e1lez Figueroa","sequence":"additional","affiliation":[{"name":"Coordinaci\u00f3n de Vigilancia Epidemiol\u00f3gica y Apoyo en Contingencias, Unidad de Salud P\u00fablica, Instituto Mexicano del Seguro Social (IMSS), 03100, Mexico City, DF, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Verdalet Guzm\u00e1n","family":"Mar\u00eda Saadia","sequence":"additional","affiliation":[{"name":"Coordinaci\u00f3n de Salud P\u00fablica, Delegaci\u00f3n Veracruz Norte, IMSS, 91810, Mexico City, DF, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soler Huerta","family":"Elizabeth","sequence":"additional","affiliation":[{"name":"Coordinaci\u00f3n de Investigaci\u00f3n en Salud, Delegaci\u00f3n Veracruz Norte, IMSS, 91000, Mexico City, DF, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rivas S\u00e1nchez","family":"Beatriz","sequence":"additional","affiliation":[{"name":"Cl\u00ednica de Medicina Tropical, Unidad de Medicina Experimental, Facultad de Medicina, UNAM, 06700, Mexico City, DF, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Altuzar Aguilar V\u00edctor","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n en Micro y Nanotecnolog\u00eda, Universidad Veracruzana, 94294, Xalapa, VER, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Navarrete Espinosa","sequence":"additional","affiliation":[{"name":"Coordinaci\u00f3n de Vigilancia Epidemiol\u00f3gica y Apoyo en Contingencias, Unidad de Salud P\u00fablica, Instituto Mexicano del Seguro Social (IMSS), 03100, Mexico City, DF, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"98","reference":[{"key":"1","volume-title":"Harrison.
