Dakar, Senegal – A leading pediatrician in Senegal is raising concerns about the risk of mother-to-child transmission of HIV, particularly during late pregnancy, and breastfeeding. Dr. Ndèye Ramatoulaye Diagne, president of the Société Sénégalaise de Pédiatrie (SOSEPED), stated that the rate of vertical transmission – the spread of HIV from a mother to her child – exceeds 7% in certain circumstances. This underscores the critical need for continued vigilance and strategic interventions to prevent pediatric HIV infections. The discussion around mother-to-child HIV transmission is particularly relevant as global health organizations strive to eliminate new pediatric HIV cases.
Dr. Diagne, who also heads the pediatric department at the Hôpital d’enfants de Diamniadio, emphasized that women are particularly vulnerable to acquiring HIV infection late in pregnancy and in the postpartum period. When a mother contracts HIV during this time, the risk of transmitting the virus to her baby significantly increases. This is especially true if the mother begins breastfeeding even as infected, as HIV can be transmitted through breast milk. Understanding the timing of infection is crucial for effective prevention strategies.
The Challenges of Late-Pregnancy Infection
The concern stems from the fact that many women in Senegal, and other regions with high HIV prevalence, may not be aware of their status until late in their pregnancy or after childbirth. Dr. Diagne explained that a woman who becomes infected late in pregnancy is at a higher risk of transmitting the infection to her child. This highlights the importance of comprehensive HIV testing programs that reach pregnant women throughout their pregnancy and immediately after delivery. The specialist in neonatology noted that identifying these cases allows for prompt intervention to minimize the risk of transmission.
Research suggests that re-testing pregnant women late in pregnancy and in the six weeks following delivery can be effective in reducing HIV prevalence, particularly in countries with high infection rates like South Africa and Kenya. Yet, Dr. Diagne cautioned that the cost of such widespread testing can be prohibitive, especially for countries with limited resources. A cost-benefit analysis is essential when considering the implementation of such programs.
Balancing Cost and Effectiveness
The economic considerations surrounding widespread HIV testing are significant. While effective in high-prevalence countries, the strategy’s cost-effectiveness diminishes beyond six weeks postpartum. Dr. Diagne pointed to the experiences of countries like Ukraine and Colombia, where the cost-benefit ratio did not justify continued testing beyond the initial postpartum period. This suggests that a tailored approach, considering local prevalence rates and economic constraints, is necessary.
Beyond timing, Dr. Diagne also highlighted the role of genetic factors and obstetric complications in HIV transmission. She noted that premature rupture of membranes and prolonged breastfeeding (beyond two years) can increase the risk of infection by as much as 15%. These factors underscore the need for a multifaceted prevention strategy that addresses both maternal health and infant feeding practices.
The Importance of Early Diagnosis and Treatment
A central tenet of preventing pediatric HIV infections is early diagnosis and treatment. Dr. Diagne stressed the importance of testing women *before* they become pregnant, ensuring they achieve viral suppression before conception. Viral suppression refers to reducing the amount of HIV in the body to undetectable levels, making transmission extremely unlikely. “It is important that children are born free of HIV, that they start their lives without HIV infection. And if they are infected, that they live without AIDS,” she stated.
Achieving this goal requires a robust healthcare system capable of providing comprehensive HIV testing, treatment, and support services. This includes access to antiretroviral therapy (ART) for pregnant women living with HIV, as well as counseling and support to aid them make informed decisions about infant feeding. The goal is to ensure that all children have the opportunity to grow up healthy and free from the burden of HIV.

Looking ahead, continued research and investment in HIV prevention programs are essential. The next steps involve evaluating the feasibility and cost-effectiveness of different testing strategies in the Senegalese context, as well as strengthening healthcare systems to ensure that all pregnant women have access to the care they need. Further investigation into genetic factors influencing transmission could also lead to more targeted prevention efforts.
