HIV can be transmitted from an infected mother to the neonate in three circumstances: across the placenta during pregnancy (in utero), at birth due to fetal contact with infected maternal genital secretions and blood, or postnatally through the breast milk. [8] This type of viral transmission is also known of as vertical transmission.
HIV is spread primarily by unprotected sex (including anal and vaginal sex), contaminated hypodermic needles or blood transfusions, and from mother to child during pregnancy, delivery, or breastfeeding. [18] Some bodily fluids, such as saliva, sweat, and tears, do not transmit the virus. [19] Oral sex has little risk of transmitting the virus. [20]
Still, the placental barrier is not the sole means to evade the immune system, as foreign fetal cells also persist in the maternal circulation, on the other side of the placental barrier. [9] The placenta does not block maternal IgG antibodies, which thereby may pass through the human placenta, providing immune protection to the fetus against ...

HIV enters the brain early on in the infection. [21] It is thought that HIV uses a "Trojan horse" mechanism to enter the brain. Normally, the blood–brain barrier (BBB) serves as a protective mechanism by preventing entry of foreign substances; disruption of the BBB by HIV contributes to the progression of infection. [22]
HIV is passed in infected body fluids such as semen, vaginal or rectal secretions, blood and breast milk, and the most common way to pass it on is through sex without a condom or sharing drug ...
Blood-brain barrier, a biological barrier that prevents entry of harmful substances into the brain by selectively allowing some substances to pass through it; Blood-testis barrier, the biological barrier between blood and testes; Blood-placental barrier, the biological barrier between a pregnant individual's blood and foetal blood (blood of one ...
