Latest: BA2 strain sparks urgent call for Covid vaccine for children under three
The BA.2 variant of the coronavirus is driving another surge of cases around the world, from the UK to America.
The number of people each sufferer could infect is believed to be 12, making it one of the world's most contagious diseases yet.
So why is BA.2 driving record case numbers, and are its symptoms more severe than earlier variants?
The National explains.
What is BA.2?
A sublineage of the Omicron family, which has three subvariants: BA.1, BA.2 and BA.3.
BA.1 was the one that originally took off and spread around the world, but BA.2 has gained a foothold now in many countries and is on the increase, leading to rises in case numbers.
One of the most interesting things about the three subvariants is that each is as different to the other as Alpha, Beta, Gamma and Delta are from each other.
The three Omicron sublineages, which were detected at the same time in South Africa, share 39 mutations. But each has some of their own. In the case of BA.1, there are 20; BA.2 has another 27, and BA.3 has 13 more.
BA.2 spreads faster than BA.1, about 30 per cent more according to estimates, which means it is easier to catch. Scientists think its extra mutations help to make it more transmissible.
“Omicron BA.2 is about 1.4 times more infectious than BA.1,” wrote former World Health Organisation scientist Prof Adrian Esterman on Twitter.
“The basic reproduction number (R0) for BA.1 is about 8.2, making R0 for BA.2 about 12.
“This makes it pretty close to measles, the most contagious disease we know about.”
The R0 of measles is between 12 and 18.
Are the symptoms more severe?
Studies in the UK and Denmark found no evidence that an infection with BA.2 is linked to a greater risk of being admitted to hospital than with BA.1. A more recent study from Qatar showed the same thing.
There had been some concern after an animal study in Japan found that BA.2 caused more severe disease in hamsters. But findings in animal studies do not always translate well to human beings.
New research from Hong Kong suggests, however, that BA.2 may be more severe in children than other variants.
They found the strain was associated with higher odds of paediatric ICU admission, mechanical ventilation and oxygen use.
“The intrinsic severity of Omicron BA.2 in children who had no past Covid-19 or vaccination is not mild,” the researchers said.
“And in fact … the Omicron BA.2 is more neuropathogenic than previous Sars-CoV-2 variants, influenza and parainfluenza viruses, resulting in more seizures.”
Although Omicron is milder in adults than Delta, BA.1 evades immunity from vaccination and other variants, making it easier for people who have been vaccinated to catch, particularly if they have not been boosted.
But BA.1 provides strong protection against BA.2, according to the WHO. So anyone who had Omicron earlier should be protected against BA.2.
Common symptoms of the variant include a cough, shortness of breath, loss of taste or smell, sore throat or hoarse voice, congestion or runny nose, and nausea or vomiting.
Why are case numbers rising?
Partly because of BA.2’s increased transmissibility, but many countries where case numbers are surging have dropped restrictions in an effort to learn to live with the virus.
Waning immunity is also believed to be playing a factor, as protection from boosters fades and many people received theirs months ago.
Case numbers have risen fast and high in the UK, but White House chief medical adviser Dr Anthony Fauci said this week he did not expect another surge right now in the US.
However, there are signs a new wave is beginning.
Wastewater surveillance at 15 sites showed an increase greater than 1,000 per cent in the virus from February 24 to March 10.
And on Thursday, New York state reported 3,875 new cases – an increase of 87 per cent from last week.
Why is it called stealth Omicron?
It gained this nickname because it was not initially clear to labs it was of the Omicron family.
PCR tests look for three genes and with BA.1 only two react, giving labs a handy shortcut to identify it.
But BA.2 does not have this missing gene. All three can be found under examination of PCR samples of BA.2, making it look like variants, such as Delta.

Farage on Muslim Brotherhood
Nigel Farage told Reform's annual conference that the party will proscribe the Muslim Brotherhood if he becomes Prime Minister.
"We will stop dangerous organisations with links to terrorism operating in our country," he said. "Quite why we've been so gutless about this – both Labour and Conservative – I don't know.
“All across the Middle East, countries have banned and proscribed the Muslim Brotherhood as a dangerous organisation. We will do the very same.”
It is 10 years since a ground-breaking report into the Muslim Brotherhood by Sir John Jenkins.
Among the former diplomat's findings was an assessment that “the use of extreme violence in the pursuit of the perfect Islamic society” has “never been institutionally disowned” by the movement.
The prime minister at the time, David Cameron, who commissioned the report, said membership or association with the Muslim Brotherhood was a "possible indicator of extremism" but it would not be banned.

The struggle is on for active managers
David Einhorn closed out 2018 with his biggest annual loss ever for the 22-year-old Greenlight Capital.
The firm’s main hedge fund fell 9 per cent in December, extending this year’s decline to 34 percent, according to an investor update viewed by Bloomberg.
Greenlight posted some of the industry’s best returns in its early years, but has stumbled since losing more than 20 per cent in 2015.
Other value-investing managers have also struggled, as a decade of historically low interest rates and the rise of passive investing and quant trading pushed growth stocks past their inexpensive brethren. Three Bays Capital and SPO Partners & Co., which sought to make wagers on undervalued stocks, closed in 2018. Mr Einhorn has repeatedly expressed his frustration with the poor performance this year, while remaining steadfast in his commitment to value investing.
Greenlight, which posted gains only in May and October, underperformed both the broader market and its peers in 2018. The S&P 500 Index dropped 4.4 per cent, including dividends, while the HFRX Global Hedge Fund Index, an early indicator of industry performance, fell 7 per cent through December. 28.
At the start of the year, Greenlight managed $6.3 billion in assets, according to a regulatory filing. By May, the firm was down to $5.5bn.
Did you know?
Brunch has been around, is some form or another, for more than a century. The word was first mentioned in print in an 1895 edition of Hunter’s Weekly, after making the rounds among university students in Britain. The article, entitled Brunch: A Plea, argued the case for a later, more sociable weekend meal. “By eliminating the need to get up early on Sunday, brunch would make life brighter for Saturday night carousers. It would promote human happiness in other ways as well,” the piece read. “It is talk-compelling. It puts you in a good temper, it makes you satisfied with yourself and your fellow beings, it sweeps away the worries and cobwebs of the week.” More than 100 years later, author Guy Beringer’s words still ring true, especially in the UAE, where brunches are often used to mark special, sociable occasions.
