From: Spatio-temporal variation of malaria hotspots in Central Senegal, 2008–2012
Evolution of the risk of being hotspot with 95%CI according to rainfall and vegetation type. Evolution of the risk of being a hotspot (continuous black curve) with 95% confidence interval (discontinuous black curves) according to weekly rainfall and vegetation type: open shrublands (panel a), grasslands (panel b), croplands (panel c), and mixed vegetation (panel d). Vertical red lines show the amount of rainfall starting from which rainfall became a risk factor
