Can mosquitoes spread AIDS?
Disease transmission among mosquitoes is biologically, not mechanically (i.e. hypodermic needle). This means that mosquitoes infected with West Nile virus, for example, have had to initially come into contact with the virus, thus the virus spends the adequate amount of time developing in the host mosquito, then it becomes a vector of this disease. In the case of AIDS, mosquitoes lack the physiology to sustain or transmit the virus to other organisms.
