了解大流行病毒的起源

Understanding the Origins of a Pandemic Virus

Carlos Xavier Hernandez, Joseph Chan, Hossein Khiabanian, Raul Rabadan

摘要:

了解传染病的起源为实施公共卫生措施提供了科学依据,这些措施可能有助于避免或减轻未来的流行病。大流行病毒的最新祖先提供了关于将人畜共患病病原体转变为全面人类大流行的一组最小基因组改变的宝贵信息。自从2009年春季第一批H1N1大流行性病毒确诊病例以来,已经提出了关于该毒株起源的几种假设。然而,它是如何、在哪里以及何时首次感染人类的,目前还远不清楚。要解开这一流行病学谜团,唯一的办法是依靠国际科学界的集体努力,增加流感分离株的基因组测序,特别是在大流行爆发前几个月收集的分离株。

英文摘要:

Understanding the origin of infectious diseases provides scientifically based rationales for implementing public health measures that may help to avoid or mitigate future epidemics. The recent ancestors of a pandemic virus provide invaluable information about the set of minimal genomic alterations that transformed a zoonotic agent into a full human pandemic. Since the first confirmed cases of the H1N1 pandemic virus in the spring of 2009, several hypotheses about the strain's origins have been proposed. However, how, where, and when it first infected humans is still far from clear. The only way to piece together this epidemiological puzzle relies on the collective effort of the international scientific community to increase genomic sequencing of influenza isolates, especially ones collected in the months prior to the origin of the pandemic.
