Lassa fever in Guinea: I. Epidemiology of human disease and clinical observations.

The arenavirus Lassa is found in West Africa, where it sometimes causes a severe illness called Lassa fever. Lassa fever has been seldom investigated outside of a few hyperendemic regions, where the described epidemiology may differ from that in areas of low or moderate incidence of disease. Through a prospective cohort study, we investigated the epidemiology and clinical presentation of Lassa fever in Guinea, where the disease has been infrequently recognized.

Long-term outcome of childhood hearing deficiency.

This report is based on the questionnaire responses of 95 young hearing-impaired adults (39 with moderate, 20 with severe and 36 with profound hearing loss) who were investigated in the department of paediatric audiology during childhood. Half of the individuals were educated in ordinary school (integration) and half in an institution for hearing-impaired children. Responses on social and professional insertion were compared with audiometric threshold and educational setting.
