Yellow fever (YF) is a virus endemic disease in tropical areas of Africa and South America. It is maintained between nonhuman primates and diurnal mosquitoes (Haemagogus sp. and Sabethes sp.) that breed in sylvatic areas where humans might be incidentally infected, but in urban areas the virus is maintained among Ae. aegypti mosquitoes and humans. There is no intermediate cycle known so far in South America, and it is presumed that the dispersion to urban areas would be due to sporadic bites to humans in the sylvatic areas where wild mosquitoes feed on monkeys Alouatta and Cebus genera, which are the main host/reservoirs of YFV. In Argentina, between 2007 and 2008, epizootics were reported in howler monkeys, causing high mortality in natural populations. This reemergence of YF represents a risk for human populations, and it is necessary to conduct studies on distribution patterns of sylvatic mosquito species that are involved in these epizootics. These species have been reported poorly in the last years, although their historical distribution covers all of Northern Argentina. In this study, we developed a database which gather all the information available in literature. The database includes: Mosquito species, Date of Capture, Method of Capture, Habitat, Etiological Agent, Geographical coordinates. Data is display in a distribution map obtained with QGIS. Once the records were obtained, distribution maps were made through QGIS. Furthermore, field studies will be conducted in a near future to update this species distribution patterns to corroborate their historical distribution.
