Introduction: Vector-borne disease surveillance is important for establishing control measuresin public health. Indigenous populations of Cordoba live in climate conditions that favor the presence of vectors that might allow the spread and emergence of hantavirus cases, rickettsial and Chikungunya fever. Objective: To establish the prevalence of Hantavirus, Rickettsia sp. and Chikungunya in theindigenous population of Tuchín, Cordoba. Materials and methods: A cross-sectional descriptive study on 190 individuals of the indigenous reservation of the municipality of Tuchín was carried out; the serum samples were collected between August and December of 2012. The following serology tests were performed: antibody IgG against Hantavirus IgG Dx Select TM (Focus Technologies, EL1600G, California, USA); indirect immunofluorescence technique for Rickettsia spotted fever group IgG and ELISA IgG antibodies against Chikungunya virus (Nova-Tec, diagnostic GmbH, CHIG0590, Germany). Results: Out of 190 analyzed sera, 5.2% (10/190) were positive for Rickettsia sp. spotted fever group, Hantavirus 7 of 87 (8.0%) and 0% for Chikungunya. Significant differences among those positive for Hantavirus and Rickettsia sp. for the variables gender, age and occupation were not found. Conclusions: The findings reveal the prevalence of Rickettsia sp. and Hantavirus in the indigenous population of Tuchín. These results are useful to establishing an alert regarding thesehemorrhagic fevers. Although no positive result for Chikungunya virus was found, this is the first epidemiological surveillance study conducted in Colombia on this virus.
