China detects Omicron BA.2.3 variant for the first time

Global&nbsp;COVID-19&nbsp;cases&nbsp;surpassed&nbsp;500&nbsp;million&nbsp;on Thursday, according to a Reuters tally, as the highly contagious&nbsp;BA.2&nbsp;sub-variant of&nbsp;Omicron&nbsp;surges&nbsp;in many countries in Europe and Asia.

The rise of&nbsp;BA.2&nbsp;has been blamed for recent&nbsp;surges&nbsp;in China as well as record infections in Europe. It has been called the "stealth variant" because it is slightly harder to track than others. &nbsp;

South Korea leads the world in the daily average number of new&nbsp;cases, reporting more than 182,000 new infections a day and accounting for one in every four infections globally, according to a Reuters analysis.&nbsp;

New&nbsp;cases&nbsp;are rising in 20 out of more than 240 countries and territories tracked, including Taiwan, Thailand and Bhutan.

Shanghai is fighting China's worst&nbsp;COVID-19 outbreak since the virus first emerged in Wuhan in late 2019, with almost 25,000 new local&nbsp;cases&nbsp;reported, although the city's quarantine policy is criticized for separating children from parents and putting asymptomatic cases&nbsp;among those with symptoms.&nbsp;

"Shanghai's epidemic prevention and control is at the most difficult and most critical stage," Wu Qianyu, an official with the municipal health commission, told a briefing.&nbsp;

Europe, US still affected

Some European countries are now seeing a slower uptick in new&nbsp;cases, or even a decline, but the region is still reporting over 1 million cases&nbsp;about every two days, according to the Reuters tally.&nbsp;

In Germany, the seven-day average of new infections has fallen and is now at 59 per cent&nbsp;&nbsp;of its previous peak in late March. New cases&nbsp;are also falling in the United Kingdom and Italy, while they are holding steady in France.

Overall,&nbsp;COVID-19&nbsp;cases&nbsp;in the United States have dropped sharply after hitting record levels in January, but the resurgence of&nbsp;cases&nbsp;in parts of Asia and Europe has raised concerns that another wave could follow in the United States.

The US&nbsp;national public health agency said on Monday the&nbsp;BA.2&nbsp;sub-variant&nbsp;of&nbsp;Omicron&nbsp;was estimated to account for nearly three of every four coronavirus&nbsp;variants in the country.&nbsp;

The&nbsp;BA.2&nbsp;variant&nbsp;now makes up about 86 per cent of all sequenced&nbsp;cases&nbsp;globally, according to the World Health Organization. It is known to be more transmissible than the BA.1 and BA.1.1&nbsp;Omicron&nbsp;sub-variants. Evidence so far, though, suggests&nbsp;BA.2&nbsp;is no more likely to cause severe disease.&nbsp;

Scientists continue to emphasize vaccines are critical for avoiding the devastation the virus can cause.

Roughly 64.8 per cent&nbsp;of the world population has received at least one dose of a&nbsp;COVID&nbsp;vaccine, although only 14.8 per cent&nbsp;of people in low-income countries have received at least one dose, according to figures from Our World in Data.&nbsp;

While&nbsp;cases&nbsp;have flared in Europe and Asia recently, the United States still has the highest total&nbsp;COVID&nbsp;infections since the start of the pandemic with 80.41&nbsp;million, followed by India with 43.04&nbsp;million&nbsp;and Brazil with 30.14&nbsp;million.&nbsp;

Since 2020, about 37 per cent&nbsp;of the world’s covid&nbsp;cases&nbsp;have been in Europe, 21 per cent&nbsp;in Asia and 17 per cent&nbsp;in North America.

About 6.5&nbsp;million&nbsp;people have lost their lives to covid since the pandemic began. The United States has reported the highest number of deaths, followed by Russia, Brazil and India.

Worldwide covid cases surpass 500 million as Omicron variant BA.2 surges

Coronavirus pandemic has been troublesome for most parts of the world in last two years. What’s more worrisome is the emergence of variants and subvariants. &nbsp;&nbsp;

One subvariant, which can prove to be as deadly as Delta and previously identified Covid variants is Omicron subvariant BA.2. It can also be called as ‘stealth Omicron’. &nbsp;

The new lab studies have revealed that this subvariant BA.2 can cause severe illnesses. Considering this, epidemiologist Eric Fang has voiced concern and wants it to be upgraded as ‘variant of concern’. &nbsp;&nbsp;

This subvariant may have features, which can make it capable of causing serious illnesses. It has immune escape properties just like sub-variant BA.1. It is resistant to treatments like sotrovimab, the monoclonal antibody. &nbsp;

Although the study is yet to be peer-reviewed, it has been posted on the preprint repository, BioRxiv. &nbsp;&nbsp;

Although BA.2 is considered as an Omicron variant, its genomic sequence is heavily different from BA.1, the researchers said. “And, this suggests that the virological characteristics of BA.2 are different from that of BA.1," they added. &nbsp;&nbsp;

In a tweet, Fang said that BA2 is seriously bad news. It’s both faster transmission than BA2 and if it’s truly more severe and as evasive against prior immunity including BA1 old Omicron immunity— then it’d be the worse of four worlds. &nbsp;&nbsp;

Covid subvariant ‘Omicron BA.2’ as deadly as Delta, says expert. What makes it worrisome?

South Africa is seeing more cases of the BA.2 sub-variant of the Omicron coronavirus variant and is monitoring it, but there is no clear sign that BA.2 is substantially different from the original Omicron strain, a senior scientist said on Friday (Feb 4).

Michelle Groome, from the National Institute for Communicable Diseases, showed in a presentation that BA.2 accounted for 23 per cent of the 450 samples from January sequenced by South Africa's genomic surveillance network and the original strain 75 per cent.

Of the 2,243 samples from December that were sequenced, BA.2 accounted for 4 per cent and the original strain 94 per cent.

&nbsp;

"We are seeing this increase with BA.2. We are still trying to get more information on this particular sub-lineage ... and so we are increasing sequencing from those provinces where we are seeing increases (in cases) monitoring the proportion that is due to BA.2," Groome told a news conference.

"At this stage, there is no indication that there would be ... differences between these different sub-lineages of Omicron. As we saw with Delta there were lots of lineages and we didn't see a lot of difference between them, but we will keep monitoring, " she added.

When asked whether there were signs BA.2 was causing different symptoms, she said she was not expecting marked changes. Scientists will analyse hospitalisation data for clues about the severity of illness linked to the sub-variant, she said.

South Africa entered a fourth wave of COVID-19 infections driven by Omicron late last year, shortly after alerting the world to the emergence of the highly transmissible variant.

Daily infections started to decline in mid-December after hitting a record of more than 26,000, and they have stabilised in recent weeks at about 3,000 new cases a day.

Health Minister Joe Phaahla said the country was not out of the fourth wave and there could be a fifth wave closer to winter. He said the past two weeks had been a bit of a "stalemate" in terms of new cases.

"There's no serious decline and yet no worrying rise in infections," he said, adding that the opening of schools and increased movement after the holidays could be reasons why there had not been a larger drop in new infections.
