Understanding Malaria Transmission: The Role of 蚊子es
While considered rare within the United States today, malaria can be extremely common in humid, hot climates and is one of the highest-occurring vector diseases worldwide.
Scroll to learn more about malaria, its transmission via mosquitoes, 以及通过杀幼虫和其他免疫控制策略帮助遏制其在社区传播的方法.
Catch an in-depth explanation of the parasite that causes malaria, its bite and infect transmission cycle via mosquitoes, more in this webinar snippet.

疟疾是由红血球感染属于疟原虫的原生动物寄生虫引起的 疟原虫 genus, with five 物种 being primarily responsible for human 感染: 疟原虫 恶性疟原虫, 间日疟原虫, 疟原虫 malariae, 疟原虫那, 疟原虫 knowlesi. Each 物种 exhibits distinct characteristics, geographic distribution, severity of the disease they cause.
到目前为止，在佛罗里达州发现的所有疟疾病例都是由 间日疟原虫 物种——广泛分布于全球，但尤其以疟疾在亚洲的传播而闻名, 拉丁美洲, the Middle East. While generally less severe than P. 恶性疟原虫 感染, 疟疾是非洲最普遍的疟疾病因，占全世界与疟疾有关的死亡人数的大部分, P. 间日疟原虫 以其在肝脏中长时间休眠的能力而闻名, 在初次感染后数月甚至数年导致疾病复发.
了解疟原虫的生命周期对于理解其传播和确定潜在的干预点以对抗它至关重要.
Malarial transmission requires two factors – a female 按蚊 蚊子和人类宿主——以及所谓的“叮咬和感染”机制.
The life cycle begins when a female 按蚊 mosquito, the vector, takes a blood meal from an infected human. 在吸血的同时，蚊子也摄入了疟原虫——在这种情况下， P. 间日疟原虫 – from the infected human’s bloodstream.
Inside the mosquito’s midgut, 疟疾寄生虫通过有性繁殖并发育成孢子体, the infective form of the parasite. 这个过程可能需要8到15天，在此期间蚊子必须存活下来. 然后这些孢子虫迁移并感染蚊子的唾液腺. 当蚊子叮咬并将孢子体注射到另一个人类宿主的血液中时，现在被认为是受感染的，并且准备好了传播疟疾寄生虫.
此时此刻, the sporozoites travel to the human’s liver, 成熟的, 形成裂殖子, travel into the bloodstream, 感染并破坏红细胞，引发疟疾热的特征性症状, 发冷, 贫血, 器官衰竭.
Most mosquito 物种 are not able to transmit malaria. Even in the case of 按蚊, a mosquito known for its ability to vector malaria, not all 物种 are able to as some do not feed on humans, are not susceptible to human malaria parasites, or have too short of lifespans for the parasite to fully 成熟的.
不过,某些 按蚊 由于它们的摄食习惯，这些物种具有向人类传播疟疾的独特能力, favorable habitats for breeding larvae and maturing into biting, flying adults and susceptibility to the 疟原虫 寄生虫:
The EPA recommends an integrated mosquito management approach, which takes a holistic approach to mosquito control, including community education, 监测, 测绘, 幼虫控制, adult mosquito control.
For areas that are more urban or developed, 特别是减少蚊子数量的最佳方法之一是杀幼虫-利用产品瞄准未成熟的蚊子, 幼虫阶段, well before they emerge as flying, biting adults that can transmit 感染.
