ROUTES OF TRANSMISSION FOR HIV INFECTIONS
What are the main routes of HIV transmission?
The main routes of HIV transmission:
unprotected sexual contact with an HIV-positive person;
sharing injecting equipment (syringes, needles) with an HIV-positive person;
vertical transmission of HIV from an HIV-positive mother to child (during pregnancy, during or after delivery, through breast milk).
The other routes of transmission are much less common. Among them, it is worth noting HIV infection through transfusions of blood or its products in countries where all donor blood samples are not necessarily tested for HIV.
Infection with infected blood on an open wound or on the mucous membrane is extremely rare. HIV is not transmitted through daily domestic contact, such as sharing a bathroom and toilet or drinking from the same cup.There have been no reported cases of infection in medical facilities after an HIV-infected patient has been exposed to saliva, urine or blood on intact skin, according to Dr. Denis Slinkin.
Is it possible to get HIV by having oral sex?
Such cases have been reported, but the risk is higher for women because the virus is usually in the sperm, although not in the same concentration as in the blood. But a man can also become infected.
The higher the concentration of the virus in a particular body fluid (semen, blood, vaginal secretions), the easier the virus is transmitted through contact.
Therefore, it is very important at what stage of the disease the partner is at: If she has recently been infected, the risk is much lower than if she was in the AIDS stage, says Dr. Denis Slinkin.
Dr. Denis Slinkin claims that the virus has a much lower chance of having oral sex than normal intercourse: the mucous membranes of the tongue, lips and mouth are less prone to disturbance than the mucous membranes of the genital organs.
