[Coexistence of mass hysteria, konzo and HTLV-1 virus in the Democratic Republic of the Congo].

A cross-sectional study was carried out in Pindi located 115 kilometers from Kikwit, Democratic Republic of the Congo to characterize a local school epidemic involving paralysis of the lower extremities, identify risk factors, and establish differential diagnosis with konzo and spastic paralysis related to human T-lymphotropic virus type 1 (HTLV-1). Data was obtained using a qualitative approach based on records, interviews, focus group technique, and neurological examination. Blood tests using the ELISA and western blot tests were performed to detect HTLV-1 and HIV 1 and 2.
