The SARS-CoV2 genomic watch device set up by the Ministry of Health reported the detection and confirmation of the circulation of the British variant and its spread in 7 regions of the Kingdom.
Indeed, indicates the ministry, the sequencing of the complete genome allowed the confirmation of the presence of signature mutations of the British variant, to date, 89 strains B.1.1.7 (British Variant) have been assigned, and no other variant of concern. (VOC) has only been confirmed in Morocco.
Recalling that since the start of the SARS-CoV2 epidemic, several thousand variants have circulated and others will emerge, the Genomic Watch Consortium reassures, however, that the appearance of these variants over time is a natural process in the history of viruses, linked to the way these microorganisms replicate.
In December 2020, a new variant of SARS-CoV-2 (known as line 20B / 501Y.V1, VOC 202012/01 or B.1.1.7) emerged in the UK, with a high number of mutations . This variant has since been detected in 130 countries including Morocco. Its transmissibility is 30 to 70% higher than strains of SARS-CoV-2 previously circulating in the world, he further emphasizes.
Other SARS-CoV-2 variants of concern, including the South African variant (B.1.351) and the Brazilian variant B.1.1.28.1 (P1) have aroused great public health interest and are being monitored. genomics and epidemiology around the world.
Alongside the specific mutations of the variants detected, new mutations are regularly detected but without clinical or epidemiological impact. This viral dynamic is observed around the world.
The ministry also indicates that the National SARS-CoV2 Genomic Watch Consortium will continue to inform the health authorities of the genetic evolution of SARS-CoV2 strains circulating in Morocco, and of the possible presence of an autochthonous variant having an impact on the disease. public health.
