The tick is common in Africa and has spread to Central America with cattle imported from Senegal in the 1800s. It is found on livestock and is considered a vector of Crimean-Congo hemorrhagic fever (CCHF) and a number of rickettsia diseases, like Ehrlichia ruminantium (syn. Cowdria ruminantium) causing heartwater, a fatal disease of ruminants. It may bite humans. The tick is apparently transported by birds like the cattle egret (Bubulcus ibis). Management typically involves the frequent application of pour-on acaricides.
