In this free ILI Pulse report, we contextualize the evolving landscape of the SARS-CoV-2 virus since the Omicron variant’s emergence in late 2021. This emergence has led to a rapid proliferation of new variants, significantly impacting global COVID-19 activity. These variants, resulting from extensive viral spread and mutations, demonstrate the virus’s dynamic nature. The Omicron variant has evolved into over 1800 sublineages. As the number of these sublineages and mutations grows, tracking the most impactful ones becomes increasingly complex.
As of November 9, 2023, the XBB lineage is the most prevalent, representing over 70% of global SARS-CoV-2 cases. This prevalence highlights the XBB lineage’s major role in the current COVID-19 landscape. Additionally, other lineages outside the XBB group are showing notable growth. Their evolution suggests potential benefits in their evolutionary pathways, possibly affecting future global COVID-19 activity significantly.
Our comprehensive report examines the Omicron variant’s global impact, offering detailed insights into its regional spread. It also spotlights three specific non-XBB SARS-CoV-2 variants requiring close monitoring. These variants may critically influence the future dynamics of COVID-19 spread, necessitating continued vigilance and research.
This ILI Pulse report is vital for grasping the emerging SARS-CoV-2 variants’ complex interactions and their effect on global COVID-19 activity.
