  1. Summary of overall tendencies in human exposure to two species of malaria vectors across Africa under two scenarios of greenhouse gas concentrations and consequent climate change, showing transitions from low-risk suitability categories to high-risk categories and vice versa, and the human population numbers that are associated.
