Evidence of CCHF in Africa using a One Health approach. The following level classification is applied: level 1, CCHF cases reported annually through established surveillance; level 2, CCHF cases reported intermittently in absence of robust surveillance; level 3, no CCHF cases reported and no robust surveillance established, but available data point toward the possibility of undetected/unreported CCHF cases (animal/human serology, CCHFV detected in Hyalomma ticks); level 4, no CCHF cases reported and no robust surveillance or epidemiologic/epizootiologic studies, but Hyalomma ticks present; and level 5, no available data. Classification at the country level was performed for policy implications. Country boundaries do not necessarily reflect the geographic area at risk and are not necessarily endorsed by the authors. The map was created using ArcGIS Release 10.61. Source: Database of Global Administrative Areas. .
