8 Key Factors That Increase HIV Transmission Risk from Parent to Infant

HIV transmission from a parent to an infant is known as mother-to-child transmission (MTCT). It can occur during pregnancy, childbirth, or breastfeeding.....CONTINUE READING THE FULL STORIES HERE

Although modern medicine has greatly reduced the chances of this happening, certain factors still increase the risk. Understanding these factors helps parents take the right steps to protect the baby. Here are eight key factors you should know.

1. High Viral Load in the Mother

A high amount of HIV in the mother’s blood is one of the strongest risk factors. When the viral load is high, the virus is easily passed to the baby. Proper treatment can reduce the viral load and lower the risk.

2. Not Using Antiretroviral Treatment (ART)

ART helps suppress HIV and protect both the mother and the infant. When a mother is not on treatment, the risk of transmission becomes much higher. Taking medication consistently throughout pregnancy is essential.

3. Poor Adherence to Treatment

Some mothers start ART but fail to take it consistently. Missing doses allows the virus to multiply again. Poor adherence increases the baby’s exposure during pregnancy and delivery.

4. Breastfeeding Without Medical Guidance

HIV can be transmitted through breast milk. In areas where safe formula feeding is available, mothers are often advised not to breastfeed. However, where formula is unsafe or unavailable, doctors guide mothers on how to breastfeed safely to reduce risk.

5. Infections During Pregnancy

Sexually transmitted infections (STIs), malaria, and other infections increase inflammation in the birth canal and placenta. This makes it easier for HIV to pass from mother to child.

6. Prolonged or Complicated Labour

A long labour or complications such as ruptured membranes expose the baby to maternal fluids for a longer time. The longer the exposure, the higher the risk of transmission.

7. Mixed Feeding in the First Months

Giving the baby both breast milk and other foods or liquids during the first six months can damage the baby’s intestinal lining. This makes it easier for HIV to enter the infant’s body.

8. Lack of Proper Medical Monitoring

Regular check-ups help doctors monitor viral load, adjust treatment, and detect any complications early. Without medical supervision, risky conditions may go unnoticed, increasing the chances of transmission.

Conclusion

HIV transmission from parent to infant can be greatly reduced when parents understand these eight risk factors. With proper treatment, regular follow-up, safe feeding practices, and good medical care, many babies born to HIV-positive mothers remain HIV-free. Awareness, early action, and consistent treatment are the most powerful tools in protecting the child’s health.
