ABSTRACT
The goal of this study was to determine the prevalence of digestive helminthiasis among patients referred to the laboratory of Parasitology and mycology at Le Dantec Hospital in Dakar for examination of stool samples from 2004 to 2009. Of 1 526 direct stool examinations (Ritchie and Baerman techniques) analyzed at the laboratory of Parasitology and Mycology of Le Dantec Hospital from 2004 to 2009, 310 were positive for intestinal helminthiasis, for a prevalence of 20.3%. The main species found were: Ascaris lumbricoides, Trichuris trichiura, Strongyloides stercoralis, Tænia saginata and Tænia solium. Most patients had a single parasite (90.1%, versus 9% with two and 0.9% with three). Men are infected more often than women, accounting respectively for 58% and 42% of the infections, for a sex ratio of 1.38. Children aged 10 to 15 years had the highest prevalence of infection: 34.5%. The results show that digestive helminthiasis is endemic in Dakar, where it is necessary to implement campaigns of deworming, health education and environmental improvement.
