Although dengue haemorrhagic fever is widely established in South-East Asia, no cases have been reported from Borneo. In order to help to assess whether the infection could become established in Borneo, a survey was made, using the single-larva collection method, of the distribution and prevalence of the principal vector, Aedes aegypti, in Sabah and in a few towns and villages of Brunei and Sarawak. In addition, the prevalence of Ae. aegypti was compared with that of certain other species of Aedes.Ae. aegypti was found to be well established in the north, east, and south-west of Sabah but to be absent from almost all of the west coast. It was either uncommon in, or absent from, several small coastal villages; in others, very high Breteau indices were recorded. No reasonable explanation for this discontinuous distribution can be suggested. Large numbers of potential larval habitats were found, giving reason to believe that Ae. aegypti will spread further within these territories.
尽管登革出血热在东南亚广泛存在，但婆罗洲尚未有病例报告。为了帮助评估该感染是否会在婆罗洲传播，采用单幼虫收集法对主要病媒埃及伊蚊在沙巴以及文莱和砂拉越的一些城镇和村庄的分布及流行情况进行了调查。此外，还将埃及伊蚊的流行情况与某些其他伊蚊种类进行了比较。结果发现埃及伊蚊在沙巴的北部、东部和西南部大量存在，但几乎在整个西海岸都没有。在几个沿海小村庄中，埃及伊蚊要么不常见，要么不存在；而在其他一些地方，则记录到了非常高的布雷图指数。对于这种不连续分布，尚无合理的解释。发现了大量潜在的幼虫栖息地，这使人们有理由相信埃及伊蚊将在这些地区进一步扩散。
