If any of these lineages is proven to have distinct characteristics as compared to the original VOC it belongs to, the TAG-VE will convene and may advice WHO to give it a separate WHO label.īA.2-like constellation in the spike protein + S:del69/70, S:L452R, S:F486V, S:Q493R reversionīA.2 + S:K147E, S:F157L, S:I210V, S:G257S, S:D339H, S:G446S, S:N460K, S:Q493R reversion The main objective of this category is to investigate if these lineages may pose an additional threat to global public health as compared to other circulating viruses. In light of the widespread transmission of the Omicron VOC across the globe and the subsequent expected increased viral diversity, WHO has added a new category to its variant tracking system, termed “Omicron subvariants under monitoring" to signal to public health authorities globally, which VOC lineages may require prioritized attention and monitoring. Each constellation may or may not differ in the public health risk it poses, and each lineage that includes substitutions in key sites may need further investigation to assess whether its characteristics diverge or not from those that define the variant of concern they stem from. Since its designation as a VOC by WHO on 26 November 2021, viruses part of the Omicron complex have continued to evolve, leading to descendent lineages with different genetic constellations of mutations. As transmission of these VOCs has been sustained, this has led to significant intra-VOC evolution. Delta reached almost 90% of all viral sequences submitted on GISAID by October 2021, and Omicron is currently the dominant variant circulating globally, accounting for >98% of viral sequences shared on GISAID after February 2022. Latest VOCs have largely replaced other co-circulating SARS-CoV-2 variants. At the present time, this expert group convened by WHO has recommended using letters of the Greek Alphabet, i.e., Alpha, Beta, Gamma, Delta which will be easier and more practical to be discussed by non-scientific audiences. When using this naming scheme and referring to the genomic sequence of SARS-CoV-2 identified from the first cases (December 2019), the term ‘index virus’ should be used. To assist with public discussions of variants, WHO convened a group of scientists from the WHO Virus Evolution Working Group (now called the Technical Advisory Group on Virus Evolution), the WHO COVID-19 reference laboratory network, representatives from GISAID, Nextstrain, Pango and additional experts in virological, microbial nomenclature and communication from several countries and agencies to consider easy-to-pronounce and non-stigmatising labels for VOI and VOC.
ALPHA GAMMA DELTA FREE
We are so excited to meet you all in August! Feel free to follow us on Instagram to keep up with our chapter during the summer.The established nomenclature systems for naming and tracking SARS-CoV-2 genetic lineages by GISAID, Nextstrain and Pango are currently and will remain in use by scientists and in scientific research. This is undeniably an incredible experience in which you will create lifelong friends. We celebrate the diversity of our women and strive to learn more about one another's backgrounds and beliefs.
We believe that the bond of sisterhood grows stronger in every moment, not solely during sisterhood nights.
Our values allow us to foster an environment where each Alpha Gam is able to be her true self and become the best she can be. Our alumni are actively involved in supporting our chapter, through funding and participation at our events. We continue to cherish each other's friendships and stay connected with one another even after the four years at Florida State University is over. Each Alpha Gamma Delta woman strives to live out each of its fifteen lines throughout her lifetime. Our chapter’s purpose stays close to our hearts and it unites us as an organization. We endeavor to follow this brand throughout and after our collegiate sorority experience.
Our International headquarters` brand is loving, leading, lasting. We are women of action who lead without fear and inspire others to impact the world. Alpha Gams possess high ideals, wisdom, and inner strength. We want to improve the lives of those around us and in our communities in which we live. We promote academic excellence, philanthropic giving, ongoing leadership, and a drive to attain a higher standard. Alpha Gamma Delta is an international women's fraternity and is committed to providing opportunities for personal development, service to others, and a space for members to forge their own paths- all through a lifelong spirit of sisterhood.
