Flow chart of manuscript screened for prevalence of HTLV-1 in blood donors, pregnant women and rural or urban adult population, living in Africa. * Two studies lacking confirmatory assay but showing 0% HTLV-1 seroprevalence with ELISA were included and were not counted in this line. ** Hospitalized patients included neurological, hematological, malignant, Kaposi, Leprosy patients and other. (a) Numbers in each study population category do not add up as some studies had data on different populations (blood donors, pregnant women and urban or rural adult population). These studies were counted in each category. (b) Two studies on healthy mothers were included. (c) Two studies on rural out-patients, presenting no severe pathology were included and considered as rural population.
