Deп¬Ѓnitive diagnosis is based on п¬Ѓnding feature eggs in the feces; treatment as for H. It seldom if period produces symptoms in the youth but is troubling to the progenitor who sees motile, seed-like proglottids (tapeworm segments) at the anus or on the covering of the stool. Infection is acquired when the kid ingests fleas that, in their larval tier, have eaten eggs from proglottids. Infection is prevented alongside keeping dogs and cats free of fleas and worms; niclosamide or praziquantel is impressive after treatment.
