[Serologic and genomic research by PCR of hepatitis C virus in different populations in Lomé (Togo)]. / Recherche sérologique et génomique par PCR du virus de l'hépatite C dans différentes populations à Lomé (Togo).

An epidemiological survey carried out on several groups at University Hospital of Lome showed that the prevalence of anti-HCV antibodies is 3.3 % among blood donors, 1.3 % in STD positive subjects and 6.1 % in hospitalized patients. The disparity of the HCV seropositivity rate was not statistically significant among HIV-infected and non-infected subjects (6.9 % vs 3.3 % respectively). The HCV RNA was most frequently recovered from patients, whose serological pattern was confirmed but also from 30 % of subjects, for whom the HCV serology was proved. This shows the limits of serological tests in Africa.
