从疯牛病病毒到禽流感 H5N1病毒,各种各样令人闻之色变的病毒,每天都可能随着发达的国际贸易、交通工具和染疫旅行者、疑似病人等侵入我们的生活环境。如何避免这些外来病毒入侵感染?上世纪初,公共卫生条件的改善以及抗生素和疫苗的诞生,传染病初步得到控制。人们以为对付传染病会轻而易举。没想到百年之后,病毒基因变异,摇身一变成为新兴传染病的病原体,卷土重来:流行性出血热、克一雅氏综合征、西尼罗河热、SARS、和人感染高致病性禽流感等“怪病”局部频发,横行全球。随着医学科学的不断向前发展,基因之谜
From the BSE virus to the H5N1 bird flu virus, all kinds of devastating viruses can invade our daily life with developed international trade, transport, infected travelers and suspected patients. How to prevent the invasion of these foreign viruses? The beginning of the last century, the improvement of public health conditions and the birth of antibiotics and vaccines, infectious diseases were initially controlled. People think it will be easy to deal with infectious diseases. Did not expect a century later, the virus gene mutation, transformed into a new infectious disease pathogens, comeback: Epidemic hemorrhagic fever, Creutzfeldt-Jakob disease, West Nile fever, SARS, and human infection with highly pathogenic avian influenza “ Disease ”Local frequent, rampant global. With the continuous development of medical science, genetic mystery
