May 30, 2024 · A COVID-19 antigen rapid test. A new variant of COVID-19, known as FLiRT, is now the most dominant strain in the U.S. This variant, which evolved from the omicron strain, is characterized by changes in its spike protein — the part of the virus that binds to host cells. ... "With this latest round of variants, this FLiRT variant, the ...
May 10, 2024 · For most of this year, the JN.1 variant of the coronavirus accounted for an overwhelming majority of Covid cases. But now, an offshoot variant called KP.2 is taking off.
May 3, 2024 · To identify variants, scientists map the genetic material of viruses (known as sequencing) and then look for differences between them to see if they have changed. Since 2020, SARS-CoV-2, the virus that causes COVID-19, has been spreading and changing globally.
May 10, 2024 · The KP.2 variant represents 28% of Covid infections in the U.S., up from just 6% in mid-April, according to data released Friday by the Centers for Disease Control and Prevention.

Feb 6, 2023 · New variants of SARS-CoV-2, the virus that causes COVID-19, will continue to occur. CDC coordinates collaborative partnerships which continue to fuel the largest viral genomic sequencing effort to date. The Omicron variant, which emerged in November 2021, has many lineages.
Jan 8, 2024 · A new variant of the COVID-causing virus SARS-CoV-2 is behind the latest surge in infections this winter, but it doesn't appear to cause more severe disease.
May 13, 2024 · The version of the Covid-19 virus behind the latest spike in infections shares many of the same symptoms as earlier variants of Sars-CoV-2 : a sore throat, fatigue, headache and a cough....
Jan 6, 2023 · XBB.1.5 is the most transmissible variant of COVID-19 yet. As 2023 begins, it’s causing the majority of cases in the U.S., but we aren’t seeing a surge like omicron caused last winter.
Mar 27, 2024 · From May 2021 onwards, WHO began assigning simple, easy-to-say labels for key variants. Considerable progress has been made in establishing and strengthening a global system to detect signals of potential VOIs or VOCs and rapidly assess the risk posed by SARS-CoV-2 variants to public health.
