Abstract
This article analyzes how dengue presented a virological challenge during the 1980s in order to explore the role of virological studies in understanding this disease and constructing expertise in arboviral diseases. Although outbreaks were reported throughout the twentieth century, dengue was barely known in the Americas until the epidemic of dengue fever in Cuba in 1981. When the disease reached the Brazilian city of Nova Iguaçu (RJ) in 1986, it became the focus of attention for a team of virologists led by Hermann Schatzmayr, who mobilized efforts after the creation of the Flavivirus Laboratory at the Oswaldo Cruz Institute.
