向GISAID提交H5N1基因组的时间过长
对病毒基因组的实时监测能够发现新的变异,评估其对传染性和疾病严重程度的影响,利用新的系统发育工具估计传播率和传播途径,以及公共卫生当局做出基于证据的决策,但这需要获得及时的基因组信息。最新的基因组信息还有助于快速、协作和跨学科研究以及基于证据的公共卫生对策(例如,疫苗开发和部署)。病毒基因的改变使高致病性H5N1禽流感能够传播给数百种鸟类和哺乳动物1,2,3,导致反复发生动物到人的传播事件。包括2024年向世界卫生组织报告的72例(参考文献4)。最近的两份报告描述了加拿大和美国的严重呼吸道感染患者,他们携带的病毒具有多态性,其基因变化先前通过深度突变扫描预测,以改善与人类细胞的结合。虽然这些变化可能促进了宿主内病毒的复制,但尚未观察到H5N1在人与人之间的有效传播。但是,这可能随时发生变化。当前H5N1基因组的实时报告是至关重要的,但我们发现,从H5N1样本收集到提交给共享所有流感数据全球倡议(GISAID)病毒数据和相关元数据储存库8,9之间存在7.5个月的广泛延迟。在COVID-19大流行的早期,之前的一项研究强调了向GISAID提交SARS-CoV-2序列的漫长延迟,样本收集和提交之间平均间隔48天。这项全球分析突出了数据共享做法迅速的国家,并指出了其他落后的国家。许多国家随后改进了数据提交的管道,2024年向GISAID提交的样本从收集到提交的时间(CST)现在降至30天。例如,加拿大在大流行早期的CST为88天,但现在SARS-CoV-2序列的中位CST仅为16天。过去几年,这些显著改善有助于全球追踪COVID-19变异并监测其传播和公共卫生影响的努力。

期刊介绍: Nature Biotechnology is a monthly journal that focuses on the science and business of biotechnology. It covers a wide range of topics including technology/methodology advancements in the biological, biomedical, agricultural, and environmental sciences. The journal also explores the commercial, political, ethical, legal, and societal aspects of this research. The journal serves researchers by providing peer-reviewed research papers in the field of biotechnology. It also serves the business community by delivering news about research developments. This approach ensures that both the scientific and business communities are well-informed and able to stay up-to-date on the latest advancements and opportunities in the field. Some key areas of interest in which the journal actively seeks research papers include molecular engineering of nucleic acids and proteins, molecular therapy, large-scale biology, computational biology, regenerative medicine, imaging technology, analytical biotechnology, applied immunology, food and agricultural biotechnology, and environmental biotechnology. In summary, Nature Biotechnology is a comprehensive journal that covers both the scientific and business aspects of biotechnology. It strives to provide researchers with valuable research papers and news while also delivering important scientific advancements to the business community.
