Do mosquitoes spread AIDS

It has been categorically proved in many ways that mosquitoes or any other insect vector cannot transmit human immuno deficiency (HIV) which is responsible for causing the acquired immuno deficiency syndrome (AIDS). In case of malaria or filarial, the mosquito acts as an intermediary host in which the parasite undergoes one life cycle. The malarial parasite multiplies in the body of a mosquito and gets collected in the mouth, ready for deposition on a host. Thus, it acts as a vector. In the case of HIV,mosquito is not a vector. The HIV cannot live in mosquito’s blood and survive in human blood only. that is why it is called Human immuno deficiency virus. The moment the virus enters the body of a mosquito it is killed. Mosquito uses its proboscis only to suck blood and not to inject blood into our body whereas a needle is used for both . this also supports the argument that HIV will not be transmitted by mosquitoes.
