No evidence to support that likelihood exists. If Human immunodeficiency virus (HIV)-infected blood is taken by a mosquito, the virus is digested (killed) inside the body of the mosquito. If a mosquito takes a partial HIV-infected blood meal from a person and then immediately feeds on an uninfected person, there would not be enough HIV particles present to transmit the disease. In fact, it is highly unlikely (1 in 10 million chance) there would even be a single unit of HIV present. Finally, for a mosquito to be able to carry AIDS, the disease would need to pass from the gut of the mosquito to the salivary glands where it would later be injected into the next host. This is quite a long and extensive process even with diseases that can be transmitted by mosquitoes (like encephalitis).
