Micronutrient deficiencies are common in HIV infected children and are aggravated by poor nutrition, especially in poor resource countries such as Uganda. It appears that micronutrient deficiencies contribute to immune dysfunction, increased morbidity and HIV disease progression. Hitherto, there has been no randomised controlled trial to assess the effect of multiple micronutrient supplementation on morbidity and mortality in HIV infected children in Africa. Therefore, the investigators shall carry out a randomised controlled trial to determine the effect of multiple micronutrient supplementation on morbidity, weight gain and mortality among HIV infected children aged 1 to 5 years in Uganda.
