Malaria transmission in the hot arid Sahel North -Eastern Nigeria: The impact of climate

Abstract

Malaria transmission season in the Sahel is short and unstable such that immunity in the populace is unable to reach a high level. The possibility of severe malaria could be very high. In areas of low malaria endemicity, such as the Sahel, malaria infection is sensitive to some climatic and other environmental changes such as temperature, rainfall, humidity, meteorological and hospital data. Decades of prolonged drought, as experienced in the Sahel, have resulted in significant reduction of malaria prevalence rates from 50% to less than 10% in some areas with a resultant improvement in immunity to malaria.
