Concern for the health of the poor is one of the critical issues in development. Poverty cannot be defined solely in terms of low or no income. Lack of access to health services, safe water, adequate nutrition, and education are also essential components of poverty. Poverty and health are closely linked. Poverty is one of the most influential factors in ill health, and ill health can lead to poverty.
Poverty drains family savings. In addition, poor people are more exposed to several risks (poor sanitation, unhealthy food, violence, drug abuse and natural disasters) and less prepared to cope with them.
