Whether the sudden increase in the number of cases is related to the new omicron strain is still unclear. But researcher Richard Lessells, who contributed to the discovery of the omicron, said the mutation would “soon become dominant”.
Mr Lessells told MPs on Wednesday night that the number of hospitalizations was rising and that the coming weeks would show the impact of the new strain.
The virus, he said, is looking for the weak to live on itself.
“Vaccinations ensure that a person does not go to the hospital, that they do not die, they work well in this new variety,” said the researcher. Also, he said, need to wear masks and keep a distance.
Dr. Dr., who works at the National Institute of Communicable Diseases Michelle Groome said the number of infections had “increased exponentially” in the past two weeks, from about 300 new cases a day to 1,000 a day last week, and more recently 3,500 new cases. 8,561 new cases were diagnosed in South Africa on Wednesday, despite an average of 1,275 people being infected a week a week ago, according to The Guardian.
“The growth rate of new cases is worrying,” said Dr. M. Groome.
The National Institute on Communicable Diseases reported that 74 percent of all coronavirus genomes sequenced last month. the new strain, which was first detected by examination of the sample, on 8 November. taken in Gautenge, the most populous province in the South Africa.
It is true that, although the number of hospitalizations is increasing, the number is far from the previous record for coronavirus waves. According to the National Institute of Communicable Diseases, in the last 24 hours. because of COVID-19 135 people were hospitalized. There are a total of 2,550 such patients.
Leading PAR researchers have warned that it is too early to claim that the omicron strain causes only a mild form of the disease, Bloomberg reports. At present, it is difficult to assess the impact of the new variant, as so far it has mainly affected young people whose bodies are better able to fight the pathogen.
In addition, the symptoms appear to appear a little later, researchers said during a presentation to lawmakers on Wednesday.
Earlier, the National Institute of Communicable Diseases said the number of new cases per day in the PAR over the past 24 hours. almost doubled (8,561 new infections). Omikron is now the dominant variety in this country.
Recent illnesses have been recorded “mainly among younger groups, but we are seeing an infected and older population as well,” Drs told lawmakers. M. Groome.
“It is also possible that more serious complications do not appear until a few weeks later,” she added.
South African researchers last week announced the discovery of a new mutant strain of pandemic coronavirus, omicron, which is thought to be highly contagious.
The World Health Organization (WHO) warned on Monday that the omicron variant poses a “very high” risk worldwide.
Many countries are trying to curb its spread by banning flights from South Africa and neighboring countries.
Researchers are also working tirelessly to analyze this option and try to understand its behavior.
It is not yet clear where the strain originated, but it was “first described in Botswana and soon after in South Africa,” said Salim Abdool Karim, South Africa’s chief epidemiologist.
South African scientists announced the discovery on November 25th.
By then, cases of omicrone had already been detected in Hong Kong.
The researchers discovered a new variant with a “very unusual number of mutations” on November 23.
Some of those mutations are already known, they affect infectivity and bypass immunity, but many others are new.
According to the WHO, the omicron strain “varies widely, has a large number of mutations, and some of them are of concern and may be related to the ability to avoid immune [atsako] and increased infectivity ’.
It has “the most mutations ever seen,” said Professor Mosa Moshabela, vice chancellor for research and innovation at Natal University in KwaZulu.
He said “some of these mutations we’ve seen before, like delta and beta,” but others are new to scientists, and “we don’t know what the combination of those mutations will be.”
Virologist Tulio de Oliveira said there were a total of about 50 mutations, including 30 mutations in the needle protein that many vaccines concentrate on because the virus gets into the cells.
It is known that some of the genetic mutations shown by the virus allow it to bypass immunity.
It is still unclear what the impact of the protection provided by the vaccines will be.
However, “based on what we know, vaccines should provide good protection against hospitalization and severe disease because they depend on T cell immunity and less on antibodies,” said SA Karim.
As for the severity of the disease caused by this option, the researchers say there is not enough data yet to draw any conclusions.
