Despite a phenomenal improvement in global health care over the past three decades, there are still strong signs that large disparities exist between poor countries and rich countries. The fact that women die from postpartum hemorrhage, children die from preventable illnesses such as pneumonia and diarrhea, or someone steps on a landmine in former war zones indicates the harsh reality that less fortunate people have to cope. There is obviously no biological reason why someone born in Mozambique would have a shorter life expectancy than someone born in the United States. Of course, there will always be economic and social differences within countries, but these should not cause widespread disease and suffering. It's completely unnecessary. This is health inequity. The question is why has it gotten to this point when the world has enough wealth and knowledge to help solve most of these problems, or at least improve the situation? Well, much of this is due to the complexity of the causal chains in each case. The combination of an unfair economy and bad policy poses a major obstacle to the quest for greater health equality. The economy is closely linked to health. Poverty is a significant underlying cause of current health inequalities. This limits access to basic resources such as sanitation, clean water and food. This often leads to infections or malnutrition, causing diarrhea and other illnesses. Furthermore, some diseases are not only the result of poverty, but have contributed to poverty. Better health allows more people to participate in the workforce, increases productivity and could add billions of dollars to the economy. On the other hand, if the majority of the population experiences health problems, then ... middle of paper ... ice and research that has resulted in increased life expectancy and decreased mortality infantile. This shows that we know how to do it and that the challenge now is to disseminate these approaches more equitably and, more importantly, to make it up to the global community to decide that it is a priority. The analysis of two factors contributing to inequalities in Health Across Countries presents the fact that those whose lives are cut short by unequal economic and political conditions are subject to brutal inequality. It is clear that large health inequalities between nations pose real challenges. Multidisciplinary approaches are needed to tackle the difficult task of untangling the intertwined causal chains involved. This will involve a joint effort by economists, epidemiologists, politicians, medical scientists and many others to reduce inequality..
