A smaller Omicron surge in spring is also possible.) [120] As it is, the variant is projected to become the dominant strain within a week. [121] The R number for Omicron in the UK is estimated to be between 3 and 5, Dr. Susan Hopkins, chief medical advisor at the UK Health Security Agency reported. The variant becomes the dominant strain in ...
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).
Similar results were found in 2022 by WHO modelers. [16] New variants of concern of the virus were found in Africa: in February 2020 the Beta variant in South Africa, [17] in December 2020 the Eta variant in Nigeria, [18] [19] and in November 2021 the Omicron variant in Botswana. [20]
The Lambda variant, also known as lineage C.37, is a variant of SARS-CoV-2, the virus that causes COVID-19. [1] It was first detected in Peru in August 2020. [2] On 14 June 2021, the World Health Organization (WHO) named it Lambda variant [1] and designated it as a variant of interest. [3] On 16 March 2022, the WHO has de-escalated the Lambda ...
The Alpha variant (B.1.1.7) was [2][3] a SARS-CoV-2 variant of concern. It was estimated to be 40–80% more transmissible than the wild-type SARS-CoV-2 (with most estimates occupying the middle to higher end of this range). Scientists more widely took note of this variant in early December 2020, when a phylogenetic tree showing viral sequences ...
The COVID-19 lockdown in the United Kingdom was a series of stay-at-home orders introduced by the British and devolved governments in response to the COVID-19 pandemic. On 23rd March 2020, Prime Minister Boris Johnson announced a nationwide lockdown to curb the widening outbreak of COVID-19.
