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.
1976年12月至1977年4月以及1978年12月至1979年1月期间，塞舌尔群岛发生了类似登革热的疾病流行。1977年，从曾在塞舌尔群岛的个体中分离出登革2型病毒。1979年2月至4月，从塞舌尔群岛马埃岛此前未因类似登革热疾病住院的门诊患者中采集血清。这些血清的中和试验结果表明，四种登革病毒的流行率在81%至91.8%之间，登革2型病毒最有可能是这些疫情的病原体。此外，还发现了针对基孔肯雅病毒（8.7%）和辛德毕斯病毒（7.4%）的抗体，首次证明了这两种甲病毒在塞舌尔群岛的存在。
