Omicron evades some, but not all, immunity and discovers South African studies

The Omicron variant appears to be able to avoid some immunity, but the vaccine remains a protection against serious illness, according to the latest data from South Africa, which is rapidly overtaking Delta to become the predominant variant. Should provide.

Omicron, which caused global concerns about the proliferation of infections, was first detected in southern Africa last week and urged governments across the continent to impose a travel ban https://www.reuters.com/world/us. -tightens-covid-19 -travel-rules-countries-race-quell-omicron-threat-2021-12-01 And take other steps to contain it.

The new variant has been detected in five of nine South African states and is likely to be present nationwide, the latest official report said Wednesday.

The number of reported cases per day doubled to 8,561. It was unclear how many of them were omicrons, as not all test samples are subject to genomic sequencing, but in the official presentation, omicrons are “rapidly becoming the predominant mutant. “.

According to the National Institute for Communicable Diseases (NICD), Omicron accounts for 74% of the 249 viral genomes sequenced in South Africa in November and collects data as part of a broader national network for genome monitoring. doing.

South Africa only performs genomic sequencing on a small portion of all samples collected weekly. NICD does not show the total number of confirmed cases of Omicron infection.

“Mutation profiles and epidemiological images suggest that Omicron can circumvent some of the immune protection (to cause infection), but protection against severe illness and vaccine death should be less affected. “The latest report from the surveillance network states.

The first sample of the subspecies detected was collected on November 8 in Gauteng, South Africa’s most populous state, where Johannesburg and Pretoria are located. Since then, it has been detected in the Eastern Cape, KwaZulu Natal, Mpumalanga and the Western Cape.

Previously, the organizers canceled the youth music festival after 36 people tested positive for COVID-19 on the site.

The Ballito Rage Music Festival began on Tuesday in the town of Ballito, north of Durban on the east coast of South Africa. Of the 940 people tested for COVID during the first eight hours of the event, 32 guests and 4 staff were positive.

It was unknown whether 36 was infected with Omicron or another mutant.

The Delta variant caused South Africa’s third wave of infection, with more than 26,000 infections peaking per day in early July.

Since the beginning of the pandemic, the country has reported nearly 3 million infections and more than 89,000 deaths, making it the most common country on the African continent.
