The WHO designates a new type of coronavirus as a 'concern variant', calling it 'Omicron'

The exception, announced by South African scientists on Thursday, was discovered in two other countries, Israel and Belgium. Botswana and Hong Kong are some of the countries where the difference has been found.

(The WHO said about 100 genome sequences of the variant have been reported so far.)

Fears that a new species of coronavirus, which is spreading rapidly, could be even more dangerous than Delta's diversity has led several countries to impose travel restrictions on affected regions, and has led to the collapse of global stock markets.

In the evening, the World Health Organization (WHO) had designated this alternative, B.1.1.529, as a variant of concern (VOC), and renamed it Omicron.

The exception, announced by South African scientists on Thursday, was discovered in two other countries, Israel and Belgium. Botswana and Hong Kong are some of the countries where the difference has been found.

The WHO has stated that there are approximately 100 genome sequences of variants reported to date. Most people infected with the virus were fully vaccinated, with at least one person in Israel also receiving a third dose of booster.

India, which on Friday announced the resumption of international aviation services from December 15, said it would increase the level of flight tests, especially those from affected countries.

In an urgent letter to provincial governments on Thursday, Health Secretary Rajesh Bhushan said the emergence of the new type "has a significant impact on public health", and urged them to be vigilant.

Scientific analysis to date suggests that new alternatives were spreading faster than any other variables, including Delta. The fact that a small number of people infected with the virus are fully vaccinated, including one with a booster dose, is an indication that this variant also has a great potential to evade the immune response.

This means that these differences are a cause for concern in at least two of the three terms used to assess how dangerous any variance is. To date, there has been no information about its potential for causing serious illness, a third important factor.

“These differences have a number of changes, some of which are related. Preliminary evidence suggests an increased risk of re-infection with this variant, compared to other VOCs, ”the WHO statement said.

"The number of these variants appears to be growing in almost every province of South Africa.

"Based on the presented evidence showing a dangerous change in Covid19 epidemiology ... WHO has designated B.1.1.529 as VOC, named Omicron," he said.

The Delta variant, first discovered in India late last year, has been the most deadly form of SARS-CoV2 in all three figures so far. It is a remarkable diversity now in many regions, and it is the cause of the second deadly wave in India, as well as the steady increase in Europe and a few other regions.

“Not everything is known about this type yet. Data is still coming in. From now on, we know it has more than 30 variables, 10 of which are in your protein spike. Whether these differences appear as rapid, or potentially potentially escalating immune responses remains to be seen. But we have to be very careful, ”said pathologist Shahid Jameel.

Vineeta Bal, an orthopedic pathologist associated with the Indian Institute of Science Education and Research (IISER), Pune, said the emergence of diversity was not an unexpected development, but authorities needed to respond with extra vigilance to ensure timely detection and effective isolation.

“Bacteria are constantly changing. That is something to be expected. But we have to be able to make sure it doesn't get into too many people, ”said Dr Bal.

He also emphasized the need to make adequate vaccines available in South Africa, where new strains are more prevalent. "This should be done first so that future events like this can be reduced with the attainment of a better goal," he said.

Geneticist Gagandeep Kang said the next two to three weeks would be a crucial time in India, when genomic observation - genetic analysis - of the virus also needed to be intensified.
