Infections in the malnourished: with special reference to malaria and malnutrition in the tropics.

The inter-relationship of malnutrition and infections is generally accepted as being synergistic, one promoting the other. Nevertheless, numerous published reports are available which highlight the contrary, that is, antagonism of poor nutrition to infections. This presentation is a review of such publications with emphasis on malaria and malnutrition in the tropics. The data presented suggest that the effect of poor diets on human malaria is related to the level of protein and energy intake, which in turn have important bearings not only on clinical nutrition but also on nutrition policy and planning, particularly in famine and famine relief. The data highlight the necessity for the integration of nutritional programmes and anti-malarial activities in areas where famine and malaria co-exist.
