Infections with Enterobius vermicularis are typically asymptomatic.The most common complaint is perianal pruritus (itching)and resultant restless sleep.Microscopic identification of the characteristic flat-sided ovum typically confirms the diagnosis.The eggs are collected using a sticky paddle or cellophane tape pressed against the perianal region.Eggs are not typically identified in feces,although they may be occasionally found in a stool specimen.
