What can people in developed countries do for them? For example, Japan is a high developed country. So Japanese can send money, teachers and doctors to these countries. In developed countries, it is not easy for many children only to live their life. They are also forced to work as cheap and illegal labour because of lacking of knowledge,technique and education. This (of course) results from poverty, low education level also causes this. If developed countries send more money, they can get more foods and medicines. So they will not suffer from hunger. If teachers who are sent from Japan teach children, their technique will become higher and they can work(if necessary) in better condition and they can get more money. As a result, their life expectancy become more longer. So development of education level equals development of life level. If doctors teach them proper knowledge about drugs, they may avoid drugs and can protect themselves from harmful objects. So they can study and work harder(fortunately or unfortunately?) and this also will make life level higher.
Today, people in developed countries are still indifferent to developing countries. It is not too much to say that our sufficient life are based on resources and works from developing countries. Especially, Japan depends on imports from them and if they lack, we can not do anything! So people who live in developed countries have responsibilities to help developing countries.
What will happen if more doctors and medical people in Japan start to pay attention to the developing world? If they do so, many contributions will account to much. Economic and medical aid will also increase. In addition, doctors may study these regions and make new medicines for diseases (especially endemic diseases). Medical staffs will also go there to help (they are of course not "sent"!!) and relief goods will be better. But help for the developing world will stop someday and then people who live there must be going to suffer again? I think the most important thing is to make the developing world independent from the developed world. So not only doctors and medical staffs but also many people should appeal to the world and make the world think about this problem more seriously. This will bring worldwide help and it will bring about individual activities as well as national activities. As a result, (though contributions and relief goods are needed at the beginning) many institutions will be improved and excellent doctors will grow in the developing world, and finally, the developing world will not need much outside help. I think this is the sort of "real" help to the developing world that is needed now.
