Figure 1From: Innovative tools for assessing risks for severe adverse events in areas of overlapping Loa loa and other filarial distributions: the application of micro-stratification mappingGeographical patterns of loiasis and onchocerciasis prevalence levels in relation to health districts reporting SAEs. Grey shading indicates SAE areas. Yellow dots indicate loiasis prevalence A. <20% B. 20 to 40% C. >40%. Brown dots indicate onchocerciasis prevalence D. <20% E. 20 to 40% F. >40%.Back to article page
