A dengue epidemic due to type 2 virus involving some 3,400 cases began in Fiji early in 1971, had a peak during May, June and July, and cases have continued to occur with a low incidence during 1972 and 1973. Many of the notified cases showed classical dengue fever symptoms and there were no confirmed cases of haemorrhagic fever. A serological survey indicated that there had been at least 20,000 subclinical infections. It is probable that the virus was introduced to Fiji either through the port of Lautoka or Nadi international airport in February 1971. The normal travel patterns of residents must have spread the virus to all the more accessible localities but, with the exception of Rotuma, it caused infections only in areas where Aedes aegypti was available as a vector. There was no evidence that pre-existing dengue type 1 serum antibody gave any protection during this epidemic.
1971年初，斐济爆发了由2型病毒引起的登革热疫情，涉及约3400例病例，5月、6月和7月达到高峰，1972年和1973年仍有低发病率的病例持续出现。许多报告病例表现出典型的登革热症状，没有确诊的出血热病例。血清学调查表明，至少有20000例亚临床感染。病毒很可能是在1971年2月通过劳托卡港或楠迪国际机场传入斐济的。居民的正常出行模式肯定已将病毒传播到了所有更易到达的地区，但除罗图马岛外，仅在有埃及伊蚊作为传播媒介的地区引发了感染。没有证据表明先前存在的1型登革热血清抗体在此次疫情中提供了任何保护作用。
