The transmission of HIV from mother to kid throughout pregnancy, childbirth, or breastfeeding is referred to as perinatal transmission. This is the most common means in which infants become infected along with HIV.
A woman that is preparing a pregnancy or that is already pregnant need to be screened for HIV and her partner need to likewise be tested. The Centers for Illness Regulate and Prevention (CDC) advises that women likewise receive a further test throughout the 3rd trimester of their pregnancy if they keep on to engage in behavior that boosts the likelihood of them transmitting HIV.
In addition, the CDC says that women that go in to labor prior to they have actually been tested need to be screened in the delivery room.

If a woman is diagnosed along with HIV either while preparing to become pregnant or throughout pregnancy, she can easily be prescribed antiretroviral therapy (ART), which significantly reduces the risk of mother-to-kid transmission. If a pregnant woman along with HIV is not treated, the risk of her baby being born along with the virus is 25%.
The strive of HIV care throughout pregnancy is to make certain the mother remains as healthy and balanced as feasible and to significantly reduce the likelihood of HIV being passed onto the baby before, during, or after birth.

The objective of ART is to lesser the quantity of HIV in the woman’s physique to a degree that is undetectable (referred to as undetectable viral load). This lowers the risk of her passing the virus onto her baby throughout pregnancy or childbirth.
Many HIV medicines are available that can easily be safely used throughout pregnancy. Healthcare providers carefully discuss along with the patient the rewards and risks of taking personal HIV drugs prior to deciding on which HIV routine to use.

- The outcomes of drug-resistance testing, which determines whether there are any sort of HIV drugs that will certainly not be effective
The favorite drug routine for women that have actually never ever taken HIV drugs prior to need to contain two nucleoside reverse transcriptase inhibitors. At least one of these need to be from the complying with drugs due to the fact that these can easily relocate across the placenta easily:
- Zidovudine
- Abacavir
- Emtricitabine
- Tenofovirdisoproxilfumurate
- Lamivudine
In addition, the routine need to contain a non-nucleoside reverse transcriptase inhibitor, an integrase strand transfer inhibitor or a protease inhibitor along with ritonavir.
