This study aimed to assess the association between schistosomiasis and hookworm infection with hemoglobin levels of schoolchildren in northern Mozambique. The authors concluded that hookworm and Schistosoma haematobium infections negatively influenced hemoglobin levels in schoolchildren. Recommendations for future programs include periodic deworming, as well as health education and improvements in sanitary infrastructure.
