SARS病毒从何而来,科学家们给出了各种猜想或解释,且都各有道理。SARS病毒从发现到认识再到了解并知道其起源,恐怕和其它病毒一样需要一定的时间,而在这不懈的探索中,除实验室研究外,笔者从其它角度提出一种假说即:SARS病毒起源于医院院内感染环境。换言之就是医院的微生物耐药环境在某一时刻使SARS病毒突变而生成。 When the SARS virus came from, scientists made a variety of conjectures or explanations, all of which make sense. SARS virus from discovery to understanding to understand and know its origin, I am afraid, like other viruses need a certain amount of time, but in this tireless exploration, in addition to laboratory research, the author put forward from another point of view a hypothesis that: SARS virus Originated in the hospital hospital infection environment. In other words, the hospital’s microbiologically resistant environment generates mutations in the SARS virus at some point.
