近一段时间,“非典”成为一个世界性的话题。其实,从某种程度上说,人类的历史就是与名目繁多的传染病斗争的历史。病菌对人类的威胁与祸害由来已久。当某种传染病菌首次侵入缺乏认识该病经验的人群时,往往会爆发大流行。传染病与人类的历史息息相关、彼此互动。在战争史上,传染病也曾以其巨大的杀伤力留下过浓重的一笔。传染病造成的人口大量损失能够扭转战争的局势;而人类的战争活动也会把传染病传播到全球各地。 Recently, “SARS” has become a worldwide topic. In fact, to a certain extent, human history is the history of fighting a great variety of infectious diseases. Bacteria have long been a threat to mankind. A pandemic pandemic often occurs when a certain type of contagious virus enters the population for the first time without a priori knowledge of the disease. Infectious diseases are closely related to human history and interact with each other. In the history of war, infectious diseases have also left a heavy stroke with their enormous lethality. The huge loss of population caused by infectious diseases can reverse the situation in war and human warfare activities can also spread infectious diseases all over the world.
