This health science senior seminar will explore programs and policies that impact child health in Low and Middle Income Countries. We will cover infectious diseases - including HIV, tuberculosis, malaria, respiratory infections and diarrhea - as well as major non-infectious causes of child morbidity and mortality, including nutrition, early child development and mental health. We will discuss the full life cycle of global health programs from building the evidence base through epidemiological studies through implementation science and monitoring and evaluation.
