Arms Assigned Interventions
Symptomatic malaria infection Dietary Supplement: Fe-57 orally, Fe-58 intravenously
Subjects will receive a test drink containing 3 mg Fe-57 in the form of labelled FeSO4 followed by 1 ml of an aqueous solution containing 50 μg Fe-58 as iron citrate.
Asymptomatic malaria infection Dietary Supplement: Fe-57 orally, Fe-58 intravenously
Subjects will receive a test drink containing 3 mg Fe-57 in the form of labelled FeSO4 followed by 1 ml of an aqueous solution containing 50 μg Fe-58 as iron citrate.
Hookworm infection Dietary Supplement: Fe-57 orally, Fe-58 intravenously
Subjects will receive a test drink containing 3 mg Fe-57 in the form of labelled FeSO4 followed by 1 ml of an aqueous solution containing 50 μg Fe-58 as iron citrate.
Schistosoma haematobium infection Dietary Supplement: Fe-57 orally, Fe-58 intravenously
Subjects will receive a test drink containing 3 mg Fe-57 in the form of labelled FeSO4 followed by 1 ml of an aqueous solution containing 50 μg Fe-58 as iron citrate.

Detailed Description:

The aim of the study is to determine how iron metabolism in subjects with infectious diseases (malaria, hookworm or S. haematobium) differs while infected and after treatment, i.e. the same individuals will be restudied while free of infection.
