New explanation about mosquitoes that cannot spread HIV

Scientists have shown that mosquitoes are not "flying needles", so they cannot infect people with HIV.

According to the World Health Organization (WHO) data, HIV / AIDS has killed about 1.6 million people every year. The path of transmission of this century's disease is mainly due to sexual intercourse - unprotected sex, blood sugar - using dirty needles, blood transfusion . However, many people still question If the mosquitoes suck blood from patients and then "burn" us, will we be infected with HIV?

Recently, Business Insider reported, scientists and Joe Conlon - former entomologist and technical advisor of the American Society of Mosquito Prevention Association, affirmed: "It is not entirely a question of lack of grounding. But mosquitoes cannot transmit HIV. " Conlon explained that, first of all, when the mosquito bites you, it sucks blood into its intestines. Here, the acid in the mosquito's stomach kills the HIV virus.

Besides, before sucking blood, mosquitoes produce saliva with antifreeze to make it easier for them to suck blood. Salivary glands and blood-sucking glands are separated in mosquitoes. The blood-sucking gland has a complex structure and is generally not the same as a needle. Simply put, mosquitoes produce saliva in their own way and suck blood in their own way.

As a result, blood is sucked in a single direction and not pumped back into the blood of the burned person. Therefore, even if the mosquito carries the blood virus from someone with HIV, the blood will never get rid of the salivary glands to get into your blood.

"For a mosquito to suck a patient's blood, it will carry on it," Colon said. "The virus can stay in the mosquito's body cavity, but it does not follow the salivary glands, or through stings to other people." It is an extremely complicated process and people who are infected with HIV are unable to. '

However, mosquitoes are capable of transmitting malaria parasites. The reason is that this parasite can grow in the gut of the mosquito, then move specifically to the salivary glands and continue the life cycle in a new person.
