Three recent outbreaks of locally acquired malaria in densely populated areas of the United States demonstrate the continued risk for mosquitoborne transmission of this disease. Increased global travel, immigration, and the presence of competent anopheline vectors throughout the continental United States contribute to the ongoing threat of malaria transmission. The likelihood of mosquitoborne transmission in the United States is dependent on the interactions between the human host, anopheline vector, malaria parasite, and environmental conditions. Recent changes in the epidemiology of locally acquired malaria and possible factors contributing to these changes are discussed.
美国人口密集地区最近发生的三起本地获得性疟疾疫情表明，这种疾病通过蚊子传播的风险依然存在。全球旅行增加、移民以及美国大陆各地存在适宜的按蚊媒介，都加大了疟疾传播的持续威胁。在美国，通过蚊子传播疟疾的可能性取决于人类宿主、按蚊媒介、疟原虫和环境条件之间的相互作用。本文讨论了本地获得性疟疾流行病学的近期变化以及导致这些变化的可能因素。
