Prevalence of malaria and arboviral infections from 2009 to 2013 in Kedougou. The monthly evolution of malaria infections frequency and prevalence as well as the frequency of arboviral infections from July 2009 to March 2013 in Kedougou. The solid black line with white dots represents the frequency of blood samples positive for malaria parasites; measures are given by the left-hand y-axis. The dotted red line with red asterisks corresponds to the ratio ‘number of samples positive to malaria’ divided by ‘total number of samples’. Vertical bars represent the frequencies of blood samples positive for arboviruses: red bars for YFV, blue bars for ZIKV, green bars for CHIKV, yellow bars for DENV-2, and dark grey bar for RVFV. Measures are indicated by the right-hand y-axis. Vertical dashed lines separate the plot by year and grey-shaded zones correspond to rainy seasons
