Arms Assigned Interventions
Experimental: Targeted screening
Screening for intestinal tapeworm carrier followed by treatment with niclosamide as indicated.
Drug: Niclosamide
Single oral dose of niclosamide determined by weight (dose: 11 to 34kg receive 1 gram, 35 to 50kg receive 1.5 grams, over 50kg receive 2 grams)
Active Comparator: Education
Community education about Taenia solium prevention.
Behavioral: Community education campaign
Education about prevention of Taenia solium infection provided in a single short (20 minute) interaction with the participant. Education was verbal with visual aids.
