Taking anti-HIV drugs can dramatically reduce the risk of you passing on HIV to your baby. Many women with HIV have given birth to HIV-negative children, by taking these precautions:
By doing these things, the chances of having a baby with HIV is very low – under 1%. If you are on HIV treatment and have an undetectable viral load, the chances are lower still: 0.1%.
There are two different ways in which anti-HIV drugs act to prevent mother-to-child transmission. First, they reduce your viral load so your baby is exposed to less HIV while in the womb and during birth. The aim of HIV treatment is to get, and keep, your viral load to undetectable levels (if your viral load is below 50, it is usually said to be undetectable).
Second, anti-HIV drugs may cross the placenta and enter your baby’s body, preventing the virus from ever taking hold. Newborn babies are given a short course of anti-HIV drugs after they are born when their mother is known to be HIV-positive.
You can reduce the risk of HIV transmission further by having a managed delivery. Your doctor will look at your viral load when you are 36 weeks pregnant and discuss options with you.
If you have an undetectable viral load, it is usually recommended you have a vaginal delivery. You will need to continue with your HIV treatment during labour.
If your viral load is detectable, but very low (under 400), your doctor will look at your particular situation and discuss options with you.
If your viral load is above 400, it is recommended you have a planned caesarean section.
Your baby should start four weeks of anti-HIV drugs in the first four hours after he or she is born, and will have an HIV test in the first 48 hours. Further tests will be done in the next months to find out his or her HIV status.
It's important to remember you should not breastfeed your baby if you have HIV as HIV is present in breast milk.
