The Chinese Center for Disease Control and Prevention shared via GISAID new hCoV-19 genome sequences from 27 provinces, collected between 2022-01-01 and 2022-03-30. Phylogenetic analyses suggest at least 35 independent introductions from outside China rather than extensive local transmission. This indicates that measures are mostly effective in disrupting long transmission chains following import.
Eleven genomes were assigned as Delta (from six distinct lineages), and 66 genomes were assigned as Omicron (from 14 distinct lineages). No highly divergent new variants were found. A small cluster of multiple cities (2x Hong Kong, 1x Shaanxi, 2x Zhejiang, 2x Yunnan, 1x Beijing) is seen in the tree tip with Hong Kong cases in the genetic base which are part of lineage BA.2.2.
The AHF Global Public Health Institute at the University of Miami and GISAID announced their collaboration to increase genomic sequencing efforts in low- and middle-Income countries.
GISAID’s ongoing work in training and skill-sharing will be leveraged to support the genomic sequencing projects AHF is currently funding. GISAID will also work with AHF to advocate for genomic sequencing and sharing as a crucial component of global public health. “Genomic sequencing, in general, is the early warning system that we need if we have additional surges from COVID-19 and other diseases” said AHF President Michael Weinstein.

First solid evidence for a Delta-Omicron recombinant virus has been shared by Institut Pasteur via GISAID (EPI_ISL_10819657 incl. raw reads). The analysis provides definite confirmation of the structure of a recombinant virus derived from the GK/AY.4 and GRA/BA.1 lineages.
This recombinant virus identified in several regions of France by the EMERGEN consortium has been circulating since early January 2022 and genomes with a similar profile have been also identified in Denmark and The Netherlands. Further investigations are needed to determine if these recombinants derive from a single common ancestor or could result from multiple similar recombination events.
The unique mix of spike amino acid changes in Omicron (clade GRA, lineage B.1.1.529 and descendants BA.1 and BA.2) is of interest as it comprises several that were previously identified to affect receptor binding and antibody escape. As with all low frequency variants with potentially relevant changes, these need to be monitored closely to study if they spread more widely as a consequence of immune escape, or altered receptor interactions. Omicron variants with and without a deletion in spike and a few other changes - BA.1 and BA.2 respectively - are co-circulating, complicating the use of PCR tests to diagnose Omicron based on “S-gene target failure”.
The timely detection of Omicron variants was made possible by researchers from Botswana, Hong Kong, South Africa who shared the first genomes of the variant.
Member States representatives met at the 72nd annual World Health Assembly in Geneva, Switzerland to discuss and debate a report prepared by the WHO on the public health implications of implementation the Nagoya Protocol.
GISAID comments on that paper, highlighting the current issues around sharing of seasonal influenza viruses, the consequences of delays in virus sharing, and the connection to the discussion at the Convention on Biological Diversity.
A peer-reviewed fact-finding and scoping study on digital sequence information on genetic resources in the context of the Convention on Biological Diversity and the Nagoya Protocol, highlights key advantages of GISAID’s sharing mechanism and a fair and equitable benefit-sharing resulting from access to data.
With the core principals of timely international sharing of health data for protecting populations against lethal infectious disease outbreaks and adherence to scientific etiquette of acknowledgement of the source of data has resulted in global trust and confidence in GISAID.
At the invitation of Germany, the first meeting of Health Ministers of the Group of Twenty leading industrialized and emerging economies (G20) took place in Berlin between 19-20 May 2017.
Under the banner of “Together Today for a Healthy Tomorrow – Joint Commitment for Shaping Global Health”, the two-day meeting focused on combating global health hazards. In their Berlin Declaration, the G20 Health Ministers recognize the importance of the Global Initiative on Sharing All Influenza Data (GISAID).
The GISAID Initiative involves public-private partnerships, among them the partnership with the Federal Republic of Germany, and governmental public-health and academic institutions in Argentina, Brazil, China, Republic of the Congo, Ethiopia, Indonesia, Malaysia, Russia, Senegal, Singapore, South Africa, and the support by Friends of GISAID, a registered non-profit association and administrative arm of the Initiative.
Congratulations to GISAID for ten years of successful work on pandemic influenza preparedness. As one of the key players in ensuring effective data sharing GISAID has made a significant contribution to global health security

Chair, Coalition for Epidemic Preparedness Innovations CEPI
Commemorating the centenary of the 1918 pandemic, the most catastrophic event in the recorded history of influenza, it is reassuring to know that GISAID is ready and prepared when a similar event emerges and threatens global health. Congratulations on bringing together one of the most successful global collaborations ever achieved

The tenth anniversary of GISAID represents a landmark in global solidarity. A pandemic strain of influenza is perhaps the world's greatest threat. Everything GISAID stands for: virus sharing, cutting-edge research, open access, and international cooperation to guarantee health security couldn't be more important

GISAID’s trustworthy data sharing principles forever transformed global collaboration in the fight against influenza, enabling unprecedented rapid response to outbreaks. In 2013, Nature called China’s sharing of H7N9 avian influenza data through GISAID ‘next to exemplary’
Prof. Dr George Fu Gao

A key to protecting the world from future viral threats is having immediate and open access to critical viral data. GISAID has established a highly effective, trusted and time-tested model for influenza data sharing that could serve as an important model for other viral families
GISAID successfully built upon the collaborative ethos of the 70-year old WHO Global Influenza Programme, to complement and extend the sharing of viruses, reagents & essential information

The GISAID Initiative was established to champion (and enhance) rapid sequence data sharing for seasonal and pandemic influenza preparedness - a global public health imperative. GISAID’s success exceeded our expectations and provides an important model for rapid data sharing for other pathogens with pandemic potential
Not all big ideas become a reality and not all big ideas fill a global need. As a public-private partnership GISAID is a model for data sharing in the digital age. On its 10th anniversary we may look back at the initial inspiration and the headline of the supporting editorial in Nature that puts the point succinctly: Sharing saves lives
