摘要

导读:登革热,传统上是一种热带疾病,近几十年来在美国的发病率显著增加。本文重点分析了气温和湿度升高期间马里兰州登革热病例的增加以及登革热病毒主要传播媒介伊蚊的地理分布范围的扩大。方法:利用电子卫生数据对2014 - 2024年登革热发病模式进行分析。对气温与登革热发病的相关性进行了分析,并对湿度因素进行了综述。结果:结果表明登革热病例的发病率在过去十年中有所增加。然而,2019-2020年登革热发病率有所下降,这可能是由于与covid -19相关的旅行限制。讨论:随着全球气温的升高,适合伊蚊的栖息地已经扩大,使它们能够在以前不适宜居住的地区繁殖。此外,较高的温度可以加快这些蚊子的生命周期和病毒复制速度,进一步增强传播潜力。湿度是另一个关键的环境因素,影响登革热蚊子的预期寿命。这项研究强调了将气候变化作为一个公共卫生问题加以解决的紧迫性,强调需要制定综合病媒管理战略和公共卫生准备,以减轻登革热在温带地区日益严重的威胁。通过了解全球变暖、湿度和登革热传播之间的相互作用,我们可以更好地为政策决策和医疗实践提供信息,以遏制这种疾病在马里兰州和美国的传播。

Uncovering the surge: dengue fever on the rise.

Introduction: Dengue fever, traditionally a tropical disease, has shown a notable increase in incidence within the United States over recent decades. This paper focuses on the increase in dengue fever cases in Maryland during increasing temperature and humidity and the expanding geographical range of Aedes mosquitoes, the primary vectors for dengue virus transmission.

Methods: Electronic health data was used to identify patterns in dengue incidence from 2014 to 2024. Correlation analysis between temperature and dengue incidence and a review of humidity factors was conducted.

Results: Results indicate an increased incidence of dengue fever cases over the past decade. However, a reduction in dengue incidence was observed in 2019-2020, likely due to COVID-19-related travel restrictions.

Discussion: As global temperatures increase, the habitats suitable for Aedes mosquitoes have expanded, allowing for their proliferation in previously inhospitable regions. Additionally, higher temperatures can accelerate the life cycle and viral replication rates in these mosquitoes, further enhancing transmission potential. Humidity, another key environmental factor, influences the life expectancy of dengue mosquitoes. This research underscores the urgency of addressing climate change as a public health issue, emphasizing the need for integrated vector management strategies and public health preparedness to mitigate the growing threat of dengue in temperate regions. By understanding the interplay between global warming, humidity, and dengue transmission, we can better inform policy decisions and healthcare practices to curb the spread of this disease in Maryland and the United States.
