摘要

登革热病毒(DENV)仍然是一个紧迫的全球卫生挑战,主要由埃及伊蚊传播。本综述综合了影响DENV传播的生物、环境和分子因素的现有知识,借鉴了120项同行评议的研究。叙述性分析强调了蚊子的媒介能力,受遗传变异、中肠屏障和免疫反应的影响。环境驱动因素,特别是温度、湿度和城市化,成为传播动态的关键决定因素。对30项研究的荟萃分析显示,两者之间存在很强的正相关(r = 0.85, p

Aedes aegypti and dengue: insights into transmission dynamics and viral lifecycle.

Dengue virus (DENV) remains a pressing global health challenge, primarily transmitted by Aedes aegypti mosquitoes. This review synthesizes current knowledge on the biological, environmental, and molecular factors influencing DENV transmission, drawing upon 120 peer-reviewed studies. The narrative analysis highlights the mosquito’s vector competence, shaped by genetic variability, midgut barriers, and immune responses. Environmental drivers particularly temperature, humidity, and urbanization emerge as critical determinants of transmission dynamics. A meta-analysis of 30 studies reveals a strong positive correlation (r = 0.85, p < 0.01) between temperature (25 °C–30 °C) and transmission efficiency. Proteomic studies further detail molecular interactions facilitating viral entry and replication. Although novel interventions such as Wolbachia-based biocontrol and genetic modification show promise, context-specific implementation remains challenging, especially in low-resource settings. Key research gaps include the impact of climate change, co-infections with other arboviruses, and the long-term efficacy of vector control innovations. Prioritizing interdisciplinary approaches and adapting strategies to local contexts are vital to reducing the dengue burden and informing future public health responses.

期刊介绍: Epidemiology & Infection publishes original reports and reviews on all aspects of infection in humans and animals. Particular emphasis is given to the epidemiology, prevention and control of infectious diseases. The scope covers the zoonoses, outbreaks, food hygiene, vaccine studies, statistics and the clinical, social and public-health aspects of infectious disease, as well as some tropical infections. It has become the key international periodical in which to find the latest reports on recently discovered infections and new technology. For those concerned with policy and planning for the control of infections, the papers on mathematical modelling of epidemics caused by historical, current and emergent infections are of particular value.
