Elephantiasis in Pawe settlement area: podoconiosis or bancroftian filariasis?

Abstract

During a pilot trial of animal trypanosomiasis control in 3 villages in Pawe settlement area of Region 6 found in northwest Ethiopia, a high frequency of people with swollen legs/feet was observed. House-to-house search in one of the villages (Village 24) indicated 68 persons, 28 males and 40 females (age ranging from 15 to 69 years) had elephantiasis of one kind or another. Based on the local population census the prevalence of elephantiasis was estimated to be 6%. Clinical examination of the 68 persons showed that about 63% had lymphoedema and/or groin lymph node swelling while parasitological examination of night blood collected between 21 and 23 hours turned to be negative. The type, magnitude and distribution of elephantiasis in Ethiopia are discussed and further study is suggested to elucidate the aetiology of the one in Pawe settlement area.
