Mosquitoes transmit diseases like malaria. So can they carry AIDS virus. The answer is a big NO. Mosquitoes do not spread AIDS.

AIDS is caused by HIV present in blood, semen and vaginal secretion of infected people. Sexual contact and exposure to contaminated blood and blood products are the chief methods through which AIDS spreads. A HIV infected pregnant woman can transmit the disease to her baby.

Lot of misconceptions regarding AIDS exists in the developing countries and third world countries. The reason why mosquitoes cannot transmit AIDS is that the virus gets destroyed inside mosquito. In simple terms, AIDS virus is digested by the mosquito.
