Abstract

Dengue fever is a viral disease caused by one of four dengue stereotypes (Flavivirus: Flaviviridae) that are primarily transmitted by Aedes albopictus (Skuse) and Aedes aegypti (L.). To safeguard public health, it is crucial to conduct surveys that examine the factors favouring the presence of these species. Our study surveyed 42 councils across four towns within the Bhakkar district of Punjab Province, by inspecting man-made or natural habitats containing standing water. First, door-to-door surveillance teams from the district health department were assigned to each council to surveillance Aedes species and dengue cases. Second, data collection through surveillance efforts, and validation procedures were implemented, and the verified data was uploaded onto the Dengue Tracking System by Third Party Validation teams. Third, data were analysed to identify factors influencing dengue fever cases. The findings demonstrated the following: (1) Predominantly, instances were discerned among individuals who had a documented history of having travelled beyond the confines of the province. (2) Containers associated with evaporative air coolers and tyre shops were responsible for approximately 30% of the Aedes developmental sites. (4) Variability in temperature was responsible for approximately 45% of the observed differences in the quantity of recorded Aedes mosquito developmental sites. (5) Implementation of dengue prevention initiatives precipitated a 50% reduction in Aedes-positive containers, alongside a notable 70% decline in reported cases of dengue fever during the period spanning 2019 to 2020, while the majority of reported cases were of external origin. Aedes control measures substantially curtailed mosquito populations and lowered vector-virus interactions. Notably, local dengue transmission was eliminated through advanced and effective Aedes control efforts, emphasising the need for persistent surveillance and eradication of larval habitats in affected regions.

通过先进的伊蚊幼虫监测和控制降低登革热发病率:巴基斯坦的成功经验。
登革热是由四种登革热定型病毒(黄热病病毒:黄热病病毒科)之一引起的病毒性疾病,主要由白纹伊蚊(Skuse)和埃及伊蚊(L.)传播。为了保障公众健康,必须开展调查,研究有利于这些物种存在的因素。我们的研究调查了旁遮普省巴克卡尔区四个镇的 42 个委员会,检查了含有积水的人工或自然栖息地。首先,地区卫生部门向每个镇派出了挨家挨户的监测小组,监测伊蚊种类和登革热病例。第二,通过监测工作收集数据,并执行验证程序,由第三方验证小组将验证后的数据上传到登革热追踪系统。第三,分析数据以确定影响登革热病例的因素。分析结果如下(1)病例主要发生在有文件证明曾出省旅行的人身上。(2)与蒸发式空气冷却器和轮胎店相关的容器约占伊蚊滋生点的 30%。(4) 在记录到的伊蚊滋生点数量差异中,约 45%是由温度变化造成的。(5) 在 2019 年至 2020 年期间,由于实施了登革热预防措施,伊蚊阳性容器减少了 50%,登革热报告病例显著减少了 70%,而大多数报告病例来自外部。伊蚊控制措施大大减少了蚊子数量,降低了病媒与病毒之间的相互作用。值得注意的是,通过先进有效的伊蚊控制措施,当地登革热传播已被消除,这强调了在受影响地区进行持续监测和根除幼虫栖息地的必要性。

期刊介绍: Established in 1910, the internationally recognised Bulletin of Entomological Research aims to further global knowledge of entomology through the generalisation of research findings rather than providing more entomological exceptions. The Bulletin publishes high quality and original research papers, ''critiques'' and review articles concerning insects or other arthropods of economic importance in agriculture, forestry, stored products, biological control, medicine, animal health and natural resource management. The scope of papers addresses the biology, ecology, behaviour, physiology and systematics of individuals and populations, with a particular emphasis upon the major current and emerging pests of agriculture, horticulture and forestry, and vectors of human and animal diseases. This includes the interactions between species (plants, hosts for parasites, natural enemies and whole communities), novel methodological developments, including molecular biology, in an applied context. The Bulletin does not publish the results of pesticide testing or traditional taxonomic revisions.
