Table 1 Human malaria vector exposure trends

From: Shifting suitability for malaria vectors across Africa with warming climates

  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.
