Climate, environment and disease: The case of Rift Valley fever

Rift Valley fever is a disease of animals and humans found throughout much of Africa, and recently in the Arabian Peninsula. It is spread via mosquito vectors and direct contact with infected tissue and fluids. Climate variability and change alter ecological processes involved in the outbreak and spread of diseases such as Rift Valley fever. This progress report reviews the key research literature on climate-driven environmental change and Rift Valley fever. The roles of regional and seasonal climates for the disease are emphasized, as well as remote sensing and other approaches to monitoring and analysis. The paper concludes with five suggested future directions for research.
