Abstract
During 1990 and 1991, dengue fever was detected in the State of Rio de Janeiro, Brazil. It occurred in two epidemic waves; one, from January to August 1990, caused predominantly by dengue virus type 1 (DEN-1) t he other from October 1990 to May 1991 caused by type 2 virus (DEN-2). Dengue was confirmed by virus isolation and/or IgM capture enzyme-lin ked immunosorbent assay (MAC-ELISA) in 2109/5964 (35-4 %) of the cases . DEN-2 virus was isolated from 180 patients. HAI tests indicated that of these previous infection with DEN-1 had occurred in 130 (72 %). Th e epidemic was classified as dengue fever, but severe and even fatal c ases occurred in association with secondary infection.
