HIV transmission from parents to an infant can occur during pregnancy, delivery, or breastfeeding. Understanding the factors that increase this risk helps families make better health decisions and seek early medical care. Below are ten key contributors every parent should be aware of.
One major factor is a high viral load in the mother. When the amount of HIV in the bloodstream is high, the chances of passing it to the baby increase significantly. Proper treatment can reduce this risk.
Another important factor is the lack of antenatal care. When a pregnant woman does not attend regular clinic visits, opportunities for HIV testing, counselling, and treatment are missed.
Not taking antiretroviral (ARV) medication during pregnancy greatly increases transmission risk. ARVs help suppress the virus, making it harder for HIV to pass to the baby.
A fourth factor is poor medication adherence. Even when ARVs are provided, failing to take them correctly reduces their effectiveness.
The mode of delivery also plays a role. In some cases, a Caesarean section may be recommended to lower the risk when the viral load is high.
Breastfeeding practices can contribute to transmission. Mixed feeding—combining breast milk with other foods—raises the infant’s risk compared to exclusive breastfeeding or formula feeding.
Another risk factor is maternal malnutrition, which weakens the immune system and may increase viral activity.
Untreated sexually transmitted infections during pregnancy can also raise the likelihood of HIV transmission.
The health of the infant matters too. Babies born prematurely or with low birth weight are more vulnerable.
Lastly, lack of partner testing and support increases overall risk, as both parents play a role in prevention and treatment adherence.
Understanding these factors empowers parents to take preventive measures and protect their infants from HIV. Early testing, consistent treatment, and proper medical guidance remain the strongest tools in preventing transmission.
