The dengue virus is indeed transmitted by the Aedes aegypti mosquito. This mosquito is a well-known vector for several viral infections that are significant public health concerns, particularly in tropical and subtropical regions.

Dengue fever, which is caused by the dengue virus, can lead to severe illness and is characterized by high fever, severe headache, pain behind the eyes, joint and muscle pain, and rash. The Aedes aegypti mosquito is efficient at spreading the dengue virus due to its close association with human habitats, as it commonly breeds in stagnant water found in urban areas.

While the Zika virus and yellow fever virus are also transmitted by the Aedes aegypti mosquito, they are distinct viruses with their own specific implications and symptoms. The West Nile virus, however, is primarily transmitted by Culex mosquitoes and not by Aedes aegypti, underlining the importance of recognizing the correct vector for each virus. This distinction is critical for effective public health interventions and mosquito control strategies focused on preventing the spread of these diseases.
