Prevalence of hookworm infection and its association with low haematocrit among resettlers in Gambela, Ethiopia.

A cross-sectional survey of hookworm infection and haematocrit (HCT) levels was conducted in 7 resettled villages and 3 indigenous villages on sample populations selected by two-stage random sampling. Of 614 resettled persons and 187 indigenous persons, 65.5% and 60.4% respectively were infected with hookworm. Mean haematocrits for 664 resettled and 222 indigenous persons were 33.1% and 35.2%, respectively. A significant association (odds ratio = 2.65) was found between low haematocrit level (below the median for the sample population) and hookworm infection in the resettled population. Suggestions are made on the need for further studies and intervention programmes.
