[The evaluation of endemic onchocerciasis in the Amou prefecture (Togo)].

We have evaluated the endemicity of the onchocerciasis in two villages of the district of Amou in Togo, Okpahoué et Onglo. We have studied 294 subjects including 136 males and 158 females representing the quarter of the population of the two villages (clinical investigation and exsanguine cutaneous biopsy): 111 persons are parasited by Onchocerca volvulus that means a prevalence rate of 37.7%. We can therefore say that the villages are in a state of "meso-endemicity". We have been able to find nodules by 20 persons among the 111 that give a percentage of 6.8 of the examined persons. Among children of 3 to 9 years old, the prevalence and the average microfilaremia are respectively 8.86 and 3.54%. Among the persons of 50 or older than 50, we found a prevalence rate of 65.95% and an average microfilaremia of 28.37.
