[Single dose mebendazole for the treatment of Trichuris trichiura and Necator americanus in chemotherapeutic control campaigns in the communities].

A study of intestinal parasitism is made in "Argelia Libre" community, Isle of Youth, by means of four coproparasitologic techniques: Kato Kratz, Ritchie, Direct, and Willis. Patients with geohelminths are divided into two groups of treatment: Group A, treated with 500 mg mebendazole in single doses and group B, treated with the classical scheme of 100 mg every 12 hours for three days. Results of treatment are expressed in terms of cure rates and percentage of egg-count reduction. When comparing schemes A and B, no significant differences are found (p less than 0.05). Due to its lower cost and easier administration, the single dosage scheme is recommended for massive chemotherapy of geohelminthiasis in the community.
