title: Serologic evidence of dengue infection before onset of epidemic, Bangladesh.
abstract: Dengue fever emerged in Bangladesh in 2000. We tested 225 serum samples from febrile patients and 184 blood donors in 1996 and 1997 for dengue antibodies; 55 (24.4% ) febrile patients had dengue antibodies ( 65.5% with secondary infection pattern), compared with one (0.54%) donor (p <0.001), suggesting that dengue transmission was ongoing well before 1996.
