AIM: Pregnant women HIV infection has main risk the contamination of newborn. MTCT actions permit to reduce that risk. MATERIAL AND METHODS: Our survey has been realized in Gabriel Touré teaching hospital gynecology and obstetrics and pediatric departments. It is about an observational prospective and descriptive survey that spreads on a period from January 2005 to December 2008. Has been included in the study all the HIV positive pregnant women followed in our service and their babies that had received ARV prophylaxis and 18 months of life serology. RESULTS: We recorded 211 HIV positive pregnant women on a total of 9291 childbirths (2.27%). We noted 90.52% of HIV-1 vs 7.11% of type 2. The mother treatment consisted in a tri therapy in 77.25 vs 0.47% of bi anti retroviral and 22.28% of mono anti retro viral therapy. Maternal viral load was undetectable at the moment of delivery in 78.20% of cases. We noted vaginal delivery in 84.36% vs 15.64% of caesarean section. Newborns respectively received 67.32%; 4.88% and 22.92% of bi, tri and mono therapy. They formula-fed in 98.98%. The mother to child HIV transmission rate was 1.98%. CONCLUSION: HIV prevalence in pregnant patients is relatively height. HARRT in HIV positive mothers associated to bi therapy and formula feeding to their infants permit to obtain low vertical HIV transmission rate.
