Summary
Brief summary
Objectives: The overall objective is to monitor efficacy of mebendazole (MBZ) against Soil-Transmitted Helminths (STH). The primary objective is: (1) to monitor the efficacy a single dose 500 mg of mebendazole (MBZ) against Soil-Transmitted Helminths (STH) infections by means of Faecal Egg Count Reduction (FECR) and Cure Rate (CR). The secondary objectives are: 1. to assess the occurrence of Necator americanus and Ancylostoma duodenal. 2. to assess the occurrence of ß-tubulin mutations related to resistance before and after drug administration. 3. to evaluate the role of dogs and pigs as reservoir for zoonotic transmission.
