What do we know about the new COVID strain found in South Africa? | Coronavirus pandemic News


A a new version of COVID-19 have been found in South Africa and the number of mutations has raised concerns among scientists and led to international sanctions for fear of the spread of coronavirus.

The National Institute for Communicable Diseases (NICD) says 22 cases of new infections have been reported in the country following a national sequence. News of the news broke Thursday.

The South African Ministry of Health, Joe Phaahla, said the discrepancy was leading to an “increase” in reported cases, creating “significant risks”.

What do we know about this new species?

A new type of COVID-19, called B.1.1.529, has an unusual number of mutations, which is worrying because it can help prevent the immune system and make it more contagious, scientists have said.

South African scientists have discovered more than 30 mutations in spike protein, a component of the virus that contributes to the entry of coronavirus into human cells.

Tulio de Oliveira, director of the KwaZulu-Natal Research and Innovation Sequencing Platform, said the change had taken experts by surprise. “There is a huge leap of evolution, more changes than we expected,” de Oliveira said.

In comparison, Beta is Type of Delta thus having three and two variables. The result came from India and it started destroying the second wave last year.

“One of the good news is that it can be detected by PCR tests,” added de Oliveira.

These mutations are linked to increased levels of antibodies, which in turn trigger viruses.

The World Health Organization (WHO) says it is “looking into” the differences mentioned and is expected to meet on Friday to determine whether they should be selected as “interesting” or “worrying”.

Does the COVID-19 vaccine work against this new type?

Covid-19 vaccine they are derived from the original coronavirus protein, raising concerns that a new spike-protein may be making the vaccine less effective.

Maria Van Kerkhove, WHO’s director of Emerging Diseases and Zoonosis, said Thursday that “the worry is that if you make too many changes, it could affect the way the virus works.”

“It will take weeks to understand how the vaccine can affect the vaccine,” added Van Kerkhove.

Any new species that could evade vaccination or spread faster than the well-known Delta species could be at high risk as the country emerges from the epidemic.

But Professor Helen Rees, of the WHO’s African Regional Immunization Technical Advisory Group, urged people not to panic.

“[Currently] we are trying to figure out how this spreads. There will be a lot of work to look at: Is it highly contagious? Is it associated with an increased risk of disease? Does it make the vaccine ineffective? ”Rees told Al Jazeera.

“In the meantime, our biggest international appeal, in terms of vaccination in the African region, please provide the vaccine in this region because as we know different races do not live in the same country,” he said.

Recognition and response

This diversity has spread rapidly in the Gauteng province of South Africa, home to Johannesburg and the capital of Pretoria.

About 50 confirmed cases have been found in South Africa, Hong Kong and Botswana. Confirmed cases in Botswana and Hong Kong were found among travelers from South Africa.

In response, Britain banned all travel from the country and five other southern African countries, namely Botswana, Swaziland, Lesotho, Namibia and Zimbabwe from noon on Friday.

Israel announced on Thursday that it was blocking its citizens from traveling to South Africa. It also included Lesotho, Botswana, Zimbabwe, Mozambique, Namibia and Swaziland in their high-risk list.

EU officials have suggested stopping flights from southern Africa to curb the spread of these new species.

Has the disease increased?

The number of daily illnesses in the country most affected by Africa has increased 10fold since that month.

The NICD said the number of people diagnosed with the disease was “growing rapidly” in three parts of the country, including Gauteng.

The NICD did not say whether it had a relapse, although some scientists doubted the cause.

The number of cases in the country reached 1,200 on Wednesday, from 106 earlier in the month.

Before recognizing the new nation, officials predicted a fourth wave would hit South Africa before the festive season, starting in mid-December.

South Africa has the highest epidemic in Africa with an estimated 2.95 million people, with 89,657 deaths.

Last year, the Beta version of the virus first appeared in South Africa, although to date its disease statistics are controlled by Delta.

About 41 percent of adults receive a single dose, while 35 percent have adequate vaccines. These figures represent more than 6.6 percent of those who received the vaccine.
