《自然》期刊近日发表了一篇文章,表明长期监测流感病毒有助于预防和控制新型病毒。通过分析H7N9禽流感病毒的进化史,科学家还预测将有更多的H7型病毒会对人类造成威胁。香港大学管轶教授与其研究团队在为H7N9禽流感爆发地区实施禽流感病毒监测和大型病毒基因组测序时,发现H7型 A recent article in Nature has shown that long-term surveillance of the flu virus helps prevent and control new viruses. By analyzing the evolutionary history of the H7N9 bird flu virus, scientists also predict that more H7 viruses will pose a threat to humans. Professor Guan Yi of Hong Kong University and his team found that when H7N9 bird flu outbreak areas were monitored for bird flu virus and the large-scale viral genome was sequenced, H7
