International audience. To assess mother-to-child transmission (MTCT) of hepatitis C virus (HCV) in Cameroon, 5,008 pregnant women were screened for HCV antibodies. Eighty-nine (1.8%) were HCV-antibody (HCV-Ab) positive. Among these, 7 (7.9%) were HBsAg positive, 6 (6.7%) HIV-positive, and one (1.1%) was co-infected by both hepatitis B virus (HBV) and HIV. Sixty-eight (76%) out of 89 HCV-Ab positive pregnant women were HCV-RNA positive. The HCV genotype determination indicated the predominance of genotype 4 (45.3%), followed by the genotypes 1 (28.1%) and 2 (26.6%). The mean HCV-RNA levels of 41 women at the time of delivery was 4.8 (range 0.06-34.7) x 10(6) RNA copies/mL. Finally, 35 women delivered 36 live children. None of those screened at 6 weeks and 6 months of age were HCV-RNA positive. The failure to detect HCV vertical transmission suggests that the mother-to-child transmission (MTCT) is not a major route of HCV transmission in Cameroon.
