Omicron: As BA.2 gains ground, experts explain if there is a need to worry

A new sub-strain of a novel coronavirus Omicron variant has spread rapidly around the world and has emerged as the latest challenge to tame Covid-19. According to the World Health Organization (WHO), the BA.2 substrain has been detected in at least 57 countries. A leading healthcare expert says people need to be cautious.

Meanwhile, Dr Wen said Omicron will not be the last variant of the coronavirus.

“Almost certainly not. New variants are emerging all the time, because that’s what viruses do: they mutate as they replicate,” she said, adding: “That’s why real-time monitoring is so important, and that’s why vaccination is the key reason.”

How transmissible is BA.2?

According to available data from governments, especially in hardest-hit Europe, the BA.2 substrain has made progress in recent months. In Denmark, for example, people infected with BA.2 transmitted the virus to an average of 39% of susceptible family members, compared with 29% for the original omicron variant. This is in line with preliminary data from the UK.

But is BA.2 more dangerous than previous strains?

Not according to the World Health Organization. Based on evidence from Denmark, the World Health Organization said this week that BA.2 did not appear to be more severe than the original Omicron variant, and that its spread did not lead to an unexpected spike in hospitalizations.

This is also reflected in the changes recently announced by the Danish government when Covid-19 restrictions ended. The Danish government says the disease is no longer a threat to society, even as cases hit a record high.

Is the vaccine effective against the BA.2 subvariant?

The latest data from Europe suggest that the existing vaccine is as effective against BA.2 as against the previous subvariant. Although BA.2 is more contagious, the vaccine blocked 13% of cases 25 weeks after a second dose of the vaccine, a British study showed.

Two weeks after the booster dose, that number increased to 70 percent.

Difference between BA.2 and BA.1

BA.2 has 40 different mutations compared to the original substrain, including key alterations in the spike region, the researchers said.

While the two are related, there are enough differences to drive behavioral change. The milder form of most Omicron cases in vaccinated populations may leave those who recover remain vulnerable to existing viruses and future variants, the researchers said.

They further stated that BA.2 will prolong the Covid-19 wave dominated by Omicron. A likely slower decline in cases could lead to higher hospitalizations and pose problems for countries with low vaccination rates.

It will “create longer tails of the Omicron loop,” says computational biologist Trevor Bedford, who works at the Fred Hutchinson Cancer Research Center.

HT Rewind 2024: Teja Sajja says HanuMan kicking off the year in style is the moment he’d been ‘waiting for’ | Exclusive

In conversation with Hindustan Times, Teja Sajja decodes the success of HanuMan and other Telugu films, talks about his upcoming projects, and more.
When Prasanth Varma’s superhero film HanuMan, starring Teja Sajja, was announced to be released alongside big films like Mahesh Babu’s Guntur Kaaram, Venkatesh’s Saindhav and Nagarjuna’s Naa Saami Ranga in January this year, no one expected the underdog to emerge on top. And yet, the film, made on a budget of under ₹50 crore, managed to collect over ₹300 crore at the box office worldwide in 25 days, becoming one of the highest-grossing Indian films for the year.

Ask Teja about the moment he realised his film had not just fought against the tide but also risen to the top; he tells Hindustan Times in an exclusive conversation, “Since I returned to acting (as a lead actor after being a child artiste since 1998), this is the moment I’ve been waiting for. When everything from the HanuMan teaser to the songs was grabbing attention, we knew we had hit a gold mine. But I don’t think we imagined it would cross the ₹300 crore threshold. We were so satisfied with the opening numbers; everything else was a bonus.”

‘Success has given me fear of disappointing people’

Teja acted in Zombie Reddy, Ishq and Adbhutham before HanuMan, but they are what you would call ‘critical successes’, adding to his repertoire as an actor who can perform. But things have changed for him now, says Teja, who is being picky about the roles he says yes to. “Success either makes you overconfident or gives you the fear of disappointing people; I have the latter,” he explains.

Teja admits he wants to chart out his career in Hrithik Roshan’s footsteps, but not in the way you think. “I have such a fondness for Hrithik due to Koi Mil Gaya and Krrish. No matter how well he performed after that, these left a lasting impression on me; I’m sure 90s kids will agree,” he says, adding, “Similarly, I’ve realised that I have an audience in children now. I want to be conscious of that when I pick roles. I want to make films families can enjoy together.”

But despite people in places like Mumbai or Delhi recognising him, Teja says he’s clear that he wants to cater to the Telugu audience first. “I am conscious that I am making films for my playground – the Telugu states. This is the sensibility I have grown up with, and I don’t know if I can cater to everyone else. Will I promote my films in other languages? Sure. But I also can’t be part of films that aren’t authentic to what I know or understand,” he explains.

‘Rootedness has put us on the world map’

And authenticity seems to be the need of the hour. Be it Baahubali and RRR or the recently released Pushpa 2: The Rule, Kalki 2898 AD and Devara: Part 1, certain kind of stories seem to be finding success. “Rootedness and going local is proving to be such a boon for us, be it in Devara or Pushpa or HanuMan. Kalki 2898 AD was our version of a Hollywood film (the sci-fi concept) with actors from across languages in predominant roles; it put us on the world map,” reflects Teja.

However, the actor admits Tollywood went through a phase of Bollywood-inspired rom-coms and family dramas that worked in their favour for a while. “That wasn’t easy to replicate either, but it’s just that these local stories are what the audience seems most interested in now. It can’t just be chalked up to religion, too. It’s about the morals these films are hinged on, the fighting for righteousness, and how an underdog can find their strength. Introducing Mahabharata or Ramayana to a new audience in a cool way is just a perk,” he says.

And it’s this rootedness that Teja says his next films, Mirai and Jai Hanuman (the sequel to HanuMan), will also have ample of. “Mirai is also a superhero film that caters to kids, but it’s not an origin story like HanuMan. It has a pan-Asian and Buddhist touch because the story is based on King Ashoka’s ideologies. I hope that I will get to deliver something new to the audience again. I will only feel like I’ve arrived if Mirai is equally, if not more, successful,” says Teja.

Rishab Shetty will headline Jai Hanuman, but Teja also looks forward to shooting that. “I can’t wait to be on that set; it’ll be exciting. Now that we know India is ready to watch our films, I want to step it up. I want to shift gears and shoot for at least two films in 2025,” he says. As for what he will do next, Teja says he wants to up the ante. “When I got a SIIMA award for Zombie Reddy as a debutant, I remember telling Prasanth this would be the last award I get. But now that I won a Radio City Cine Award for Best Actor, I hope more awards will follow,” he signs off cheekily.
