HIV transmission through breastfeeding: problems and prevention

Area of Science:

• Public Health
• Infectious Diseases
• Pediatrics

Background:

• Sub-Saharan Africa bears the highest burden of HIV in women and children.
• Breastfeeding, crucial for infant health, poses a risk of HIV mother-to-child transmission (MTCT).
• Maternal and infant factors influencing MTCT via breastfeeding require further research.

Purpose of the Study:

• To review current strategies and challenges in preventing HIV MTCT through breastfeeding in low-resource settings.
• To identify factors contributing to HIV MTCT risk during breastfeeding.
• To evaluate the effectiveness and feasibility of interventions in resource-limited countries.

Main Methods:

• Review of existing literature and intervention strategies for HIV MTCT prevention.
• Analysis of factors associated with increased MTCT risk, including maternal health and infant feeding practices.
• Examination of implementation challenges for VCT, ARV, and infant feeding recommendations.

Main Results:

• Advanced maternal HIV, high viral load, mastitis, and infant thrush increase MTCT risk.
• Interventions like VCT, ARV, and safe infant feeds face low acceptance due to stigma, cost, and resource limitations.
• High rates of mixed feeding increase MTCT risk, while exclusive breastfeeding presents a complex balance between MTCT risk and infant morbidity/mortality.

Conclusions:

• Effective HIV MTCT prevention requires addressing stigma, cost, and healthcare system weaknesses.
• Exclusive breastfeeding for six months, followed by appropriate complementary feeding, remains a vital strategy for vulnerable populations.
• Further research on ARV efficacy during breastfeeding is needed to optimize infant protection.
