Infant mortality, maternal health problems, HIV / AIDS, malaria and other diseases have many points of contact with malnutrition. A malnourished person has a weakened body, the more chances of disease and fewer defenses to cope. A sick body is more likely to fall into a state of malnutrition. A community ill will have less ability to work and jeopardize food security and their descendants. Hunger and disease are, thus, a vicious circle. Action Against Hunger has worked in the prevention and treatment of major diseases in developing countries through: emergency medical care in nutrition, primary health care, maternal and child health programs, immunization, essential drugs and education health.
