Except for noncommunidable diseases, people in both developed and developing countries suffer from similar diseases. I think this fact indicates both kinds of countries have come to have similar life styles and habits. For example, smoking is an apparent habit which leads people to similar diseases. But most members of the Japanese medical community have standard training, and conduct their treatments in similar ways when in Japan. In developed countries, there must be a system of medical training and care standards similar to those in Japan. But, in developing countries, there may be vastly dissimilar medical conditions. We have to find new ways to distribute medicines and medical care to developing countries' people.
As a first step, we should try to decrease diseases like tuberclosis that have a clear way for examination and treatment by Japanese doctors and nurses. A second step is that we must not let developing countries make the same mistakes Japan used to make. The mistakes I am referring to are largely related to air and water pollution. Even now, there are some people who suffer from this pollution that took place in the 1950-70s when Japan was a developing country. Developed countries today have to teach their knowledge about pollution to developing countries. A third step, then, is that we try to find and keep conditions for maintaining good health, without distinction between developed and developing countries.
