Vector-borne diseases and their incidence in the northern Cameroon particularly the Far North Region have been
recurrent and are on the increase. This paper assesses the impact of climate variability on the health of the
population of the Far North Region of Cameroon which is characterised by a tropical semi-arid climate in the
vicinity of the Lake Chad. Secondary data sources (Epidemiologic, climatic, ecologic, socio-economic data),
questionnaires, interviews and focus group discussions provided relevant data. The paper examines the
relationship between the outbreak of diseases and variations in some climatic elements. It highlights the
relationship that exists between the direct effects of climate variations and the development of vector-borne
diseases and their effect on human health. The results reveal a strong positive correlation between changes in the
climatic elements and the incidence of vector-borne diseases particularly cholera and meningitis. The study makes
proposals on ways of militating against the impact of vector-borne diseases on human development in the region.
