Mother to baby

A woman holding a photo of an ultrasound

Women with HIV can now give birth to healthy babies with little risk of them getting the virus. Testing during pregnancy and effective HIV drugs mean very few HIV positive babies are now born in the UK.

Can you be born with HIV?

Yes, if a pregnant woman doesn’t take HIV treatment her baby can be born with HIV.

The baby can get HIV while still in the womb - this is called mother-to-child transmission, MTCT or vertical transmission.

HIV transmission from mother to baby can also occur during childbirth following contact with the mother’s blood. If the baby isn’t born with HIV it can get it soon afterwards by feeding on infected breast milk.


How can you prevent HIV passing to a baby before birth?

In the UK very few babies are now born with HIV: 99.9% of babies born to mothers with HIV do not get infected, as long as the mother takes HIV drugs before giving birth.

Pregnant women are offered an HIV test during pregnancy. If they are found to have HIV they start treatment. (Everyone with HIV is now recommended to start treatment as soon as possible, based on the findings of the START study.)

Treatment should lower the amount of HIV in their body to undetectable levels, dramatically cutting the risk of the virus being passed on to their unborn baby.

These drugs also mean that during childbirth the risk of HIV infection is greatly reduced. As a precaution, a mother might be advised to give birth by a Caesarean delivery if her viral load is not undetectable.


How can you prevent a baby from getting HIV after birth?

Whatever way she gives birth, the mother will be advised to bottle-feed her new baby so that the child does not get infected though breast milk containing HIV.

For a month after being born the baby will also be given HIV medication to be extra sure it does not become infected. HIV drugs are safe and pose no risk to the baby.

Can't pass it on

People on effective treatment can't pass on HIV

If everyone knew this, we could bring an end to stigma and stop HIV transmissions.
