Root Explanation

Onchocerciasis is derived from "oncho-" (from Greek "onchos", meaning hook) and "cercus" (from Greek "kérkos", meaning tail). The term refers to a disease caused by the parasitic worm Onchocerca volvulus, which has a hook-like structure and is associated with the tail-like appearance of its larvae. Thus, onchocerciasis describes a disease related to the hook-like features of the parasite.

Memory Tip

Think of the 'hook' ('oncho-') and 'tail' ('cercus') of the parasite to remember that onchocerciasis is a disease caused by a worm with these features.
