title: The epidemiology of onchocerciasis in Northwestern Ethiopia.
abstract: The prevalence of onchocerciasis has been investigated by means of quantitative skin snips for the first time in Northwestern Ethiopia. One thousand three hundred and seventy people (10%) of the population of five villages near the Sudan border were surveyed. There were 267 microfilaria carriers (19.5%) and 21 (1.5%) nodule carriers. The mean number of microfilariae per infected person was 3.6 mf/mg of skin. The infection rate in men was about three times that for women. The extent of this focus needs to be delineated.
