We report results of epidemiological investigations which indicate that tick-borne borreliosis is endemic in all regions of Senegal north to the 13 degrees 30'N latitude and is a major cause of morbidity in these areas. Our findings indicate a considerable range extension for the vector tick Alectorobius sonrai and suggest that the persistence of Subsaharan drought is responsible for a large spread of tick-borne borreliosis in West Africa. specialized EPIDEMIOLOGIE VECTEUR ENDEMIE FACTEUR CLIMATIQUE SECHERESSE BORRELIOSE FIEVRE RECURRENTE A TIQUE SENEGAL 052TIAC01 41 1 136-141 1996 1427-941X https://www.documentation.ird.fr/hor/fdi:010016506 1427-941X [F B010016506] https://www.documentation.ird.fr/hor/fdi:010016506 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/pleins_textes_7/b_fdi_53-54/010016506.pdf IRD - Base Horizon / Pleins textes 1998-12-30 2025-05-23 fdi:010016506 fre
