Dengue, a self-limiting viral illness of the tropics, appears to be the infectious disease of the 21st century in many countries because of its heavy disease burden and socioeconomic impact. It was first reported in Nepal in the southern plains in 2004. Since then, there have been frequent outbreaks in that region. Kathmandu, the capital of Nepal, which is located higher north of the plains, faced its first outbreak during the monsoon in July, 2019. The city has become an ideal breeding ground for the Aedes vector mosquito because of climate change, relentless and haphazard urbanisation, brisk trade and transit from dengue-infested areas, and poor health infrastructure, all conducive to the spread of dengue.^,  Aedes mosquitos fly only 500 m in their lives, so have the potential to rapidly spread infection in a closely-packed population.

为尼泊尔加德满都的登革热爆炸做准备。

登革热是热带地区的一种自限性病毒性疾病，由于其沉重的疾病负担和社会经济影响，在许多国家看来是21世纪的传染病。该病于2004年在尼泊尔南部平原上首次报道。此后，该地区频繁爆发。尼泊尔首都加德满都位于平原的北部，在2019年7月的季风期间首次爆发。由于气候变化，无情和随意的城市化，该城市已成为伊蚊矢量的理想繁殖地，来自登革热疫区的贸易和过境蓬勃发展，以及医疗基础设施薄弱，这些都有助于登革热的蔓延。^，  伊蚊 蚊子的生命只有500 m，因此有可能在人群密集的地方迅速传播感染。
