Between December 1976 and September 1977 the Seychelles group of islands in the Indian Ocean was struck by an extensive epidemic of dengue fever. The peak of the epidemic was in the last week of February. Type 2 dengue virus was isolated from patients and mosquitos. Aedes albopictus was the sole vector. The clinical picture was that of classical dengue. Haemorrhagic fever and the shock syndrome were not observed.Absenteeism from schools and offices, anamnestic questioning, and prevalence of antibodies in sera collected after the epidemic was over, indicated that approximately 75% of the population had been infected. Serological evidence was obtained of an epidemic of dengue in the islands more than 40 years earlier. This was confirmed by archival records.
1976年12月至1977年9月期间，印度洋上的塞舌尔群岛遭受了一场大规模登革热疫情的袭击。疫情高峰出现在2月的最后一周。从患者和蚊子中分离出了2型登革病毒。白纹伊蚊是唯一的传播媒介。临床症状为典型的登革热。未观察到出血热和休克综合征。学校和办公室的缺勤情况、既往病史询问以及疫情结束后采集的血清中抗体的流行情况表明，约75%的人口受到了感染。血清学证据显示，40多年前该群岛曾发生过登革热疫情。档案记录证实了这一点。
