Does the Aedes mosquito spread We checked with the National Environmental Agency on your two questions. To answer your first question on why only the Aedes mosquito can transmit dengue: Not all mosquitoes can transmit dengue due to a combination of factors, including the biology of the mosquito species (where it breeds, if it bites human) and the dengue virus, the ability of the virus to survive in the mosquito, and the ability of the virus to multiply in the mosquito (if the virus survives). These factors must be met before a mosquito can transmit dengue. For example, if a mosquito from a different species bites a dengue-infected person, it cannot further transmit dengue because the virus may be killed by the mosquito's immune system, or the virus may survive but cannot multiply. Note that the transmission of any mosquito-borne diseases requires 3 components: the host (human), the vector (Aedes mosquito) and the pathogen (dengue virus) in the case of dengue. To answer your second question on whether the Aedes mosquito can spread other diseases: Yes, Aedes mosquitoes can also transmit other diseases such as Chikungunya and yellow fever (restricted to Africa and South America).
