SARS-CoV-2 is the virus that causes coronavirus disease 2019 (COVID-19). Jul 29, 2021 · The hoax about the Ligma variant on COVID-19 being rampant went viral after illustrator Danny Hellman posted a series of tweets suggesting the increase of COVID-19 cases in hospitals. Before lunging at and groping a screaming Mokey. 6 days ago · The XEC variant is the most dominant COVID-19 strain as of spring 2025. It is a recombinant variant, meaning it emerged from the genetic combination of two Omicron sublineages: KS. Sep 1, 2023 · The World Health Organization (WHO) names new coronavirus variants using the letters of the Greek alphabet, starting with the Alpha variant, which emerged in 2020. , accounting for a significant majority of cases. 7) The Alpha strain is the most common variant of concern in Canada, accounting for more than 216 000 cases of COVID-19 across the country as of June 17.
