La Crosse Encephalitis (LAC) is transmitted by which type of mosquito?

• A. Anopheles mosquitoes
• B. Aedes mosquitoes
• C. Culex mosquitoes
• D. Psorophora mosquitoes

Answer: (B)

La Crosse Encephalitis (LAC) is primarily transmitted by Aedes mosquitoes, specifically Aedes triseriatus, also known as the Eastern treehole mosquito. These mosquitoes are capable of transmitting the virus to humans, particularly in wooded or forested areas where they breed in tree holes and other water sources. The unique behavior and breeding habitats of Aedes mosquitoes facilitate the lifecycle of the virus, making them the primary vector for LAC. Understanding the transmission dynamics is crucial for mosquito control strategies, as targeting the right species of mosquito can significantly improve public health outcomes in areas where La Crosse Encephalitis is a concern. Control measures may include habitat management to reduce breeding sites or the use of appropriate insecticides that target Aedes mosquitoes specifically.
