HI Hazem.

I can think of several causes:

1) Lack of global governance an common objectives:

The word does not have a global government that could make us all work towards common goals. The World Health Organization, as a specialized agency from the United Nations, has among its written objectives: "the attainment by all people of the highest possible level of health".

Also, global strategies such as the Millenium Development Goals (MDGs) have tried to create a common international agendas to sum up efforts with clear objectives. But again if one country does not comply, nobody can force them.

Each country health workforce has objectives thinking on their own problems and not the global ones.

2) Health care is not only a basic need but a giant business

When you see the prices of new drugs and vaccines, you can understand how difficult it will be for many of the poorest people to get access to them. Very few actors controlling the pharmaceutical, biomedical and vaccination industry: less competence, higher prices.

3) Not enough investment in health in many places

4)  Lack of public health perspective for many health workers and health systems

5) Lack of media pressure to focus on the most important health gaps worldwide

I completely agree with Daniel's thoughtful response. I will add a bit of nuance:

The World Health Organization (WHO), is supposedly the common link between all the world's health systems. Unfortunately, most developed countries do little more than provide agreement with the conceptual underpinnings of the various activities and reports put out by the WHO.

For example, how can the US play a greater role in improving the health of undeveloped and developing countries, while not even guaranteeing the provision of basic health care (or insurance) to millions within its own borders? Many citizens would be angered if the US government would spend taxpayer dollars to support health care systems abroad while not providing it locally.

Of course, it takes an epidemic like Ebola to get developed countries to pitch in financially, and with their own medical teams, in order to contain the epidemic.

Perhaps if chronic illness were portrayed as an epidemic that could bring down the global economy, then developed countries would take their role within WHO more seriously.

Thanks Daniel & Ariel for your valuable comments. I think also that bad political behavior of the so called developed countries against the so called developing countries leads to poor world healthcare. Also lack of peace between world nations is a principle cause because millions of people were killed by wars more than those killed by diseases e.g. during the first & second world wars. Even recent wars in different areas of our earth due to failure of political interaction leads to distribution of diseased, handicapped & killed persons. So, dirty wars every where is the most fatal epidemic in the world nowadays. All nations are responsible either by direct or indirect sharing or even by just watching without seeking to solve the causes of these dirty wars. Constructing peace & justice is the only way to help the world healthcare improvement because the outcome will be no more traumatized, burned, handicapped & killed persons and money will be no more spent on wars but will be spent on improving the economy of all countries & proportionally improving the world healthcare. Ariel, do you agree with me that the so called developed countries is a wrong & false terminology which encourages racism & cut the relations between different nations. I think we are all developing countries because we are all dependent on each other. We will be developed countries when we only live independently & this is impossible. I can say that there is a country which is number one in economy but is the last in other field & so on. I can summarize that a world full of peace & justice means no more wars or terrorism leading to increase of world healthcare.  This is a dream which can really be realized & came true when there is a wise, justice political behavior working for goodness & inter-respect.           

No, I don't think that developed countries are encouraging racism. I believe that all countries put their own interests before anyone else. Self-interest is is a natural phenomenon.

If we want to have global participation in improving the world's health, then somehow this issue needs to rise in importance. We can't get universal cooperation in slowing global warming, so why would we believe that we can tackle a much larger (and immediate) problem of global health?

I clarify my opinion. Using a false descriptive names of our countries (developed versus developing) increases the gap between different countries due to increase of selfish culture, superiority & racism. Each country is better than other countries in some fields, not in all fields & so we are all developing countries because we are dependent on each other. Rights are for all but without exceeding the rights of others. I thinks healthcare team allover the world treat the bad outcome of bad political behavior responsible of everywhere wars results in form of increases of related disease, traumatized, handicapped & killed persons. Increasing culture of peace, cooperation will help much in stability of our world to direct spending of money towards the goodness of all human being.
