Due to the lack of understanding of AIDS, many people are afraid of talking about AIDS, and their sensitivity and fear of AIDS is also obvious. There are even many people ask strange questions, one of the most asked in the summer, is “mosquito bites will transmit HIV?” The answer is definitely not. Why will not the specific reasons, can be from the laboratory scientific research results and AIDS epidemiological findings of the two aspects of proof.
Experimental scientific research results from the following aspects of the mosquito bite will spread the possibility of AIDS.
1, AIDS can not be like malaria, dengue fever, epidemic B encephalitis, etc. through the mosquitoes spread. These latter diseases can survive and increase the number of pathogens in the body of mosquitoes, and then reach the salivary glands of mosquitoes, when the mosquito bites people, the saliva containing pathogens injected into the human body so that people infected. But the AIDS virus in the mosquito body can not survive, it is digested by the mosquito as food.
2, the bite of HIV-infected mosquitoes on the mouthparts of the number of HIV is far from enough to infect the next person it bites; In addition, when the mosquito bites people are killed, from the bite of the skin wound into the human body the number of HIV is far from enough to cause infection.
3, some people ask, the mosquito’s long mouthpiece is like a hypodermic syringe, why the syringe can spread HIV, but the mosquito will not? Because the mosquito’s esophagus and saliva tube is not the same tube. It spits out saliva from one tube, and inhales blood from the other tube. The inhalation of blood is one-way, will not be spit out by the esophagus, which is different from the injection syringe. Therefore, the mosquito in the bite to suck blood, it will not have sucked into the belly of the blood (its food) and then spit back into the body of the bitten person.
The results of epidemiological studies of AIDS also disprove the possibility that mosquito bites can transmit AIDS. Since the beginning of the AIDS epidemic, all infected people have been infected through blood, sexual or mother-to-child transmission channels. There are no mosquito bites that have infected the parents, brothers, or sisters of the world’s millions of infected people, although most of them live together year-round.
