Detection and Genome Sequencing of SARS-CoV-2 Variants Belonging to the B.1.1.7 Lineage in the Philippines

Coronavirus disease 2019 (COVID-19) is an infectious disease that has gained pandemic status from the World Health Organization, with millions of cases and deaths recorded worldwide. This global health crisis is caused by the virus referred to as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a member of the genus Betacoronavirus (Coronaviridae), together with the causative agents of the first SARS outbreak in 2003 and the Middle East respiratory syndrome (MERS) in 2012.

PGC SARS-CoV-2 Bulletin No. 4: Newly reported variant in the United Kingdom has yet to be observed locally

In a report posted at the Global Initiative for Sharing All Influenza Data (GISAID) website, the UK variant is said to harbor multiple spike protein mutations within a single sample, including a combination of the following: H69del, V70del(69), Y145del(143), N501Y, A570D, D614G, P681H(674), T716I, S982A, and D1118H (GISAID, 2020). While the discovery of this new UK variant appears to be concerning, the report cautions that the detailed effects of these mutations remain to be fully determined.
