摘要:Epidemics of dengue-like illness occurred in the Seychelles from December 1976 to April 1977 and from December 1978 to January 1979. Dengue 2 virus was isolated from individuals who had been in the Seychelles in 1977. From February to April 1979, sera were collected from outpatients in Mahé, Seychelles, who had not previously been hospitalized with a dengue-like illness. Results of neutralization tests with these sera indicated that prevalence rates for the four dengue viruses were between 81% and 91.8% and that dengue 2 was the most probable etiological agent in the epidemics. In addition, antibodies to chikungunya (8.7%) and Sindbis (7.4%) viruses were found, providing, for the first time, evidence of the presence of these two alphaviruses in the Seychelles.
