Abstract
Dengue (DEN) reemergence was first detected in Salta, Argentina, in 1997. It was confirmed by serology and PCR that DEN-2 virus was responsible for sporadic cases and indigenous transmission. A laboratory-based surveillance system allowed the detection of an outbreak in Salta several months later. In total, 378 DEN cases were laboratory diagnosed out of 646 (58%) studied. The cases were distributed in 10 localities of the province between January 3rd and May 31st, 1998. One DEN-2 viral isolation and 4 PCR products were obtained from patients coming from Orán and Embarcación localities. Male and female cases occurred at a similar rate (1:1), with adult cases (82.5%) nearly five times greater than for children under 15 years-old (17.5%). Clinically, all cases corresponded to classic DEN. This is the first time that a DEN outbreak has been laboratory-diagnosed in Argentina and also the first time that DEN virus has been isolated in this country.
