Q and A


My viral load is undetectable, can I transmit HIV to my baby?

My viral load is 22 and cd4 is 356. Can I transmit to my unborn.? I am 5 months pregnant.


Thanks for getting in touch.

Its great to hear that your viral load is undetectable, this is really important when thinking about transmission.

At this time its not possible to say if your baby will be born positive or not. However the risk will be reduced due to you being on medication. For more info about pregnancy, please see here:

    Hi Joyce,

    Thanks for our comment and congratulations on your new baby.

    It’s good that you are on ART with an undetectable VL. So you are doing all you can to protect your baby.

    But yes you’re right, it’s not recommended to mix feed with breast milk and formula. It’s good that you have decided to formula feed only.

    Can you talk to the nurse about feeding your baby? You can also talk about any worries you have. It would be good to have the clinic’s support. It can help keep you informed about feeding him.

    Hi Anne,
    It’s great that you’re viral load is undetectable and you’re benefitting from HIV treatment (ART). The benefits of ART are not just to your own health. Treating your HIV will reduce the risk of your baby becoming HIV positive to almost zero.

    Without ART, one in four babies born to HIV positive women will be born HIV positive. But ART can almost completely prevent transmission of HIV.

    Here’s the guide to HIV, pregnancy and women’s health.

    Hi Gal,

    Yes its OK to change from breast milk to formula milk. Babies usually don’t need water until they are older.

    Can I stop breastfeeding at 3 months and give my baby formula and water?
