Yellow Fever is transmitted by the Aedes mosquito. These mosquitoes are primarily responsible for the transmission of several diseases, including Yellow Fever. Aedes mosquitoes are most active during the day and are commonly found in tropical and subtropical regions. They breed in stagnant water sources like ponds, water containers, or discarded tires.

While other mosquitoes like Anopheles, House-flies, and Culex can transmit other diseases such as Malaria, Dengue, and Zika, they are not the primary carriers of Yellow Fever. It is important to note that Yellow Fever can only be transmitted to humans through the bite of an infected mosquito. Therefore, taking precautions to prevent mosquito bites, such as using mosquito repellents and wearing protective clothing, is essential in areas where Yellow Fever is prevalent.
