Senegal Grapples with Rising Risk of Mother-to-Child HIV Transmission
Dakar, Senegal – A leading pediatrician in Senegal has raised concerns about a heightened risk of vertical HIV transmission, exceeding 7%, during childbirth or breastfeeding. Dr. Ndèye Ramatoulaye Diagne, President of the Société Sénégalaise de Pédiatrie (SOSEPED), highlighted the increased vulnerability of mothers acquiring HIV late in pregnancy and during the postpartum period.
The Critical Window: Late Pregnancy and Breastfeeding
Dr. Diagne, who also heads the pediatric service at the Diamniadio Children’s Hospital, explained that women who become infected with HIV towards the end of their pregnancy face a significantly elevated risk of transmitting the virus to their babies. This risk is compounded by breastfeeding, as the virus can be passed through breast milk.
“It’s conceivable that a woman contracting HIV late in pregnancy, coinciding with the start of breastfeeding, will present a greater risk of infecting her child,” Dr. Diagne stated during a recent public conference.
Evaluating Screening Strategies: Cost vs. Benefit
Researchers are exploring the feasibility of routine HIV screening for pregnant women late in their pregnancy and in the postpartum period. Studies have shown that re-testing in the six weeks following delivery can be effective in reducing prevalence in countries with high HIV rates. However, Dr. Diagne noted that the cost of extending screening beyond this timeframe can be prohibitive.
Successful implementation of this strategy has been observed in countries like South Africa and Kenya, but its cost-effectiveness hasn’t been consistently demonstrated in regions like Ukraine and Colombia.
Senegal’s Unique Context and Genetic Factors
While the strategy has proven effective elsewhere, Dr. Diagne suggests it may not be immediately viable for Senegal, primarily due to cost considerations. She also pointed to the potential role of genetic factors in influencing HIV transmission rates.
Obstetrical factors also contribute to the risk. Premature rupture of membranes and prolonged breastfeeding (beyond two years) can increase the risk of transmission by as much as 15%, underscoring the need for comprehensive prevention strategies.
A Vision for HIV-Free Generations
Dr. Diagne emphasized the ultimate goal: ensuring children are born free of HIV and, if infected, can live without developing AIDS. Achieving this requires early diagnosis and prompt treatment.
“It’s important to remember that it is desirable for children to be born free of HIV, that they start their lives without HIV infection. And if they are infected, that they live without AIDS,” she stated.
Proactive Screening Before Pregnancy
A key recommendation is to screen women for HIV before they become pregnant, ensuring viral suppression before conception and throughout pregnancy. Achieving viral suppression before delivery is crucial.
FAQ
Q: What is vertical HIV transmission?
A: Vertical transmission refers to the spread of HIV from a mother to her child during pregnancy, childbirth, or breastfeeding.
Q: What is viral suppression?
A: Viral suppression means reducing the amount of HIV in the body to a very low level, making it undetectable and significantly reducing the risk of transmission.
Q: Is breastfeeding safe if a mother is HIV-positive?
A: Breastfeeding carries a risk of HIV transmission. Alternatives should be discussed with a healthcare professional.
Q: What is SOSEPED?
A: SOSEPED is the Société Sénégalaise de Pédiatrie, the Senegalese Pediatric Society.
Did you know? Early diagnosis and treatment of HIV in infants can dramatically improve their health outcomes and quality of life.
Pro Tip: Regular prenatal care and HIV testing are essential for all pregnant women, regardless of their risk factors.
