前言近年来,传染病的发展变化是显著的,它不仅在全世界范围内,在日本国表现得也更加突出。从历史上看,人类有史以来危害生命的烈性传染病中,天花已在地球上绝迹;鼠疫仅在极小的区域内流行;霍乱虽然还在发展中国家蔓延,但在发达的国家已被控制。环境卫生改善和预防接种对这些传染病的防治起了很大作用。本文就传染病的发展趋势进行总结论述。
Preface In recent years, the development of infectious diseases has notably changed. It has become more prominent not only in the world but also in Japan. Historically, smallpox has disappeared on Earth from among the potentially life-threatening human infectious diseases of mankind; plague has spread only in very small areas; and although cholera is still spreading in developing countries, it has been controlled in developed countries . Environmental sanitation improvement and vaccination have played a significant role in the prevention and control of these infectious diseases. This article summarizes the development trend of infectious diseases.
