The world is becoming urban. The UN predicts that the world's urban population will almost double from 3·3 billion in 2007 to 6·3 billion in 2050. Most of this increase will be in developing countries. Exponential urban growth is having a profound effect on global health. Because of international travel and migration, cities are becoming important hubs for the transmission of infectious diseases, as shown by recent pandemics. Physicians in urban environments in developing and developed countries need to be aware of the changes in infectious diseases associated with urbanisation. Furthermore, health should be a major consideration in town planning to ensure urbanisation works to reduce the burden of infectious diseases in the future.
世界正在变得城市化。联合国预测,到 2050 年,世界城市人口将从 2007 年的 33 亿增加近一倍,达到 63 亿。其中大部分增长将出现在发展中国家。城市的指数级增长对全球健康产生了深远的影响。由于国际旅行和移民,城市正成为传染病传播的重要中心,最近的大流行就证明了这一点。发展中国家和发达国家的城市环境中的医生需要了解与城市化相关的传染病变化。此外,在城市规划中应将健康作为一个主要考虑因素,以确保城市化有助于减轻未来传染病的负担。
