Sep 1, 2023 · Since the beginning of the pandemic, we’ve seen a number of prominent variants, including Alpha, Beta, Delta, and Omicron. Although new variants are an expected part of the evolution of viruses, monitoring each one that surfaces is essential in ensuring we—in the U.S. and globally—are prepared.

Mar 27, 2024 · Currently circulating variants of concern (VOCs) as of 15 March 2023. Note: To better reflect the current variant landscape, which is dominated by Omicron descendent lineages, WHO updated its tracking system and working definitions of VOCs and VOIs on 15 March 2023. 4 October 2023.
Variants of severe acute respiratory syndrome coronavirus 2 ( SARS-CoV-2) are viruses that, while similar to the original, have genetic changes that are of enough significance to lead virologists to label them separately. SARS-CoV-2 is the virus that causes coronavirus disease 2019 (COVID-19).
Dec 18, 2023 · Tracking SARS-CoV-2-variants. Working definitions and primary actions. Currently circulating COVID-19 Variants of Interest (VOIs) as of 18 December 2023. Currently circulating COVID-19 Variants under Monitoring (VUMs) as of 10 February 2024.
Nov 4, 2023 · The main variant in the United States is omicron. This variant spreads more easily than the original virus that causes COVID-19 and the delta variant. But omicron seems to cause less severe disease. Omicron has a few major offshoots, also called sublineages. Together the omicron variants make up nearly all COVID-19 infections in the United States.
