Studies on the epidemiology of Ternidens deminutus and hookworm infection in Rhodesia have shown that the former infection is still widespread in this country in both human and monkey hosts. The loads, however, tend in Man to be relatively low. Hookworm infection is also fairly widespread but seems largely to be an introduced infection with a high prevalence among immigrant Africans. The prevalence in these immigrant Africans drops as does the load with lengthening stay in Rhodesia although in areas of high rainfall or with overhead irrigation, the prevalence in Rhodesia may be high. Loads of hookworm in Rhodesian Africans seem to be usually low. Both hookworm and T. deminutus appear to increase in the warm rainy season (October to March) and to drop during the cold dry months. It was also found that the prevalence of hookworm and T. deminutus in males and females was about the same, although females carried significantly higher loads of hookworm than did mates. As regards infection of different age groups with these helminths there seemed to be a tendency for the younger age groups to be infected with T. deminutus (but not very young children under two years of age) while hookworm was commoner in young adults. A review of the treatment of human infections with T. deminutus is included in the paper.
