Abstract:
Dengue infection may be asymptomatic and may produce the typical symptoms of a benign illness or serious hemorrhagic and often fatal symptoms. Asymptomatic cases are statistically relevant and quite variable depending on the geographic area under study. However, there are no reports of asymptomatic population infected by the dengue virus in Misiones. In this study, 288 samples were analyzed, and the IgG anti dengue antibodies detected accounted for 6.6% of cases, while 89% corresponded to individuals who lived with people diagnosed or suspected of having contracted dengue, p= <0.001.
