COVID-19 pandemics has led to genetic diversification of SARS-CoV-2 and the appearance of variants with potential impact in transmissibility and viral escape from acquired immunity. We report a new and highly divergent lineage containing 21 distinctive mutations (10 non-synonymous, eight synonymous, and three substitutions in non-coding regions). The amino acid changes L249S and E484K located at the CTD and RBD of the Spike protein could be of special interest due to their potential biological role in the virus-host relationship.

Article Synopsis
  • COVID-19 was first detected in Colombia on February 26, 2020, in a traveler from Italy, but there's limited information about its origins in the country.
  • Researchers sequenced the SARS-CoV-2 virus from 43 clinical samples and analyzed 79 existing genome sequences to study how the virus entered Colombia.
  • The study identified multiple introductions of the virus from Europe, documenting over 12 lineages and emphasizing the importance of genome sequencing in understanding the outbreak's evolution and transmission.
