“…Since then, DF has become endemic in many areas of Colombia and adjacent countries (Gratz & Knudsen, 1996). Large epidemics involving several dengue viral serotypes were reported from Colombia in the 1970s (D-1 V, D-2 V and D-3 V), 1980s and 1990s (D-1 V, D-2 V and D-4 V; Boshell et al, 1986;Acosta et al, 1990). Increased numbers of the more severe dengue haemorrhagic fever (DHF) occurred in Colombia since 1990(PAHO, 1994Osorio et al, 1996) information on the dengue virus serotypes responsible for these cases was specified in only one report by Acosta et al, 1990. For active surveillance of DF in endemic areas, the Pan American Health Organization (PAHO) has recommended monitoring of disease through collection of clinical, virological and entomological data on a regular basis (PAHO, 1994).…”

Adult Aedes aegypti mosquitoes were collected in Puerto Triunfo, central Colombia, where dengue is endemic, during a six month period. Viral infection within the head of each individual mosquito was identified by an immunofluorescent assay (IFA) using a flavivirus-specific monoclonal antibody. The dengue virus serotype, present in each flavivirus-positive specimen, was then determined in portions of the remaining thorax using IFAs with serotype-specific monoclonal antibodies. Among 2065 female Aedes aegypti collected and tested, twenty-four flavivirus-positive individuals were found (minimum infection rate 11.6%), three identified as dengue type-1 and twenty-one as dengue type-2 virus. This was consistent with the isolation of only these two serotypes of dengue virus from dengue fever patients within this town. No vertical transmission of dengue virus could be detected in 1552 male Aedes aegypti collected. This method is inexpensive, simple, rapid to perform and suitable for use in developing countries to identify and distinguish different serotypes of dengue virus in their vectors during eco-epidemiological investigations.
