Abstract
Prevalence of hookworm infection was measured in Cameroon during a national survey carried out for a schistosomiasis research project. The survey provided a representative sample of the 10–19 year age group for each one of the 49 administrative divisions. Prevalences were low in the Extreme North province with a sahelian climate. Prevalences were high in the provinces with an equatorial climate except for the Centre province which is more developed. Regions with tropical Cameroonian climate, which receive a very heavy rainfall, showed the highest prevalences. Urbanized areas had lower infection rates than rural areas.
It should not be assumed that hookworm prevalence is uniformly high throughout a tropical country. Since hookworm distribution shows wide variations, large control programmes should start with a thorough evaluation of the situation.
