This case study examined current trends in the prevalence of vector-borne diseases and the impact of climate change on disease distribution. Our findings indicate that the dynamics of the Anopheles mosquito population in particular has changed dramatically in the past decade and now poses an increasing threat to human populations previously at low risk for malaria transmission. Given their geographic location and propensity for sustaining vector-borne disease outbreaks, southeastern states are particularly vulnerable to climate-induced changes in vector populations. We demonstrate the need to strengthen our hospital and laboratory infrastructure prior to further increases in the incidence of vector-borne diseases by discussing a case of uncomplicated malaria in a patient who arrived in one of our hospitals in Louisiana. This case exemplifies a delay in diagnosis and obtaining appropriate treatment in a timely manner, which suggests that our current health care infrastructure, especially in areas heavily affected by climate change, may not be adequately prepared to protect patients from vector-borne diseases. We conclude our discussion by examining current laboratory protocols in place with suggestions for future actions to combat this increasing threat to public health in the United States.
本案例研究考察了当前虫媒传染病的流行趋势,以及气候变化对疾病分布的影响。我们的研究结果表明,过去十年中,疟蚊种群的动态发生了巨大变化,现在对以前疟疾传播风险较低的人群构成了越来越大的威胁。鉴于它们的地理位置和维持虫媒传染病爆发的倾向,东南部各州特别容易受到气候引起的蚊虫种群变化的影响。我们通过讨论路易斯安那州一家医院收治的一名无并发症疟疾患者的病例,展示了在虫媒传染病发病率进一步上升之前,我们需要加强医院和实验室基础设施的必要性。这个病例说明了诊断和及时获得适当治疗的延误,这表明我们现有的医疗保健基础设施,特别是在受气候变化严重影响的地区,可能没有充分准备好保护患者免受虫媒传染病的侵害。我们在讨论中还检查了目前的实验室方案,并提出了未来应对美国公共卫生这一日益严重威胁的行动建议。
