Some countries may see another wave of COVID-19 infection due to XBB subvariant: WHO chief scientist
Pune, Oct 20: Chief scientist at the World Health Organization (WHO), Dr Soumya Swaminathan, on Thursday said some countries may see "another wave of infections" with the XBB subvariant of Omicron, a variant of COVID-19 virus.
Talking to reporters on the sidelines of the annual general meeting of the Developing Countries Vaccine Manufacturers Network (DCVMN) here, she clarified that as of now, there was no data from any country to suggest that these new variants are clinically more severe.
"There are over 300 subvariants of Omicron. I think the one that is concerning right now is XBB, which is a recombinant virus. We had seen some recombinant viruses earlier. It is very immune-evasive, which means it can overcome the antibodies. So slightly that we may see another wave of infections in some countries because of XBB," she said.
Swaminathan said they are also tracking derivatives of BA.5 and BA.1, which are also more transmissible and immune-evasive.
As the virus evolves, it is going to evolve more and more transmissible, she said.
"As of now, there is no data from any country to suggest these new subvariants are more clinically severe," she clarified.
Suggesting the measures that need to be taken, Dr Swaminathan said monitoring and tracking are the key steps.
"We need to continue to monitor and track. We have seen that testing has gone down across countries, the genomic surveillance has also gone down over the last few months. We need to maintain at least a strategic sampling of genomic surveillance so that we can keep tracking the variants as we have been doing and studying," she said.
According to her, the Director General of the WHO has said that COVID-19 continues to be a public health emergency of international concern.
She added that 8,000 to 9,000 deaths are being reported every week worldwide due to the infection.
"So we have not said that the pandemic is over, which means that all precautions and tools continued to be used. Good thing is that we have now many tools and the most important thing is vaccines," Dr Swaminathan said.
"As far as vaccine coverage is concerned, our goals are 100 per cent of people over the age of 60 and 100 per cent of health care and frontline workers. Then we have a goal of achieving 70 per cent of the country, but subgroups are more important because they are most likely to face morbidity and mortality," she said.
She said that a number of deaths from elderly groups were seen when Omicron spread as they were not fully vaccinated.
"The full vaccination schedule is actually three doses. The primary two doses plus booster in the next four to six months. But in many countries, including India, the uptake of the booster is low. So we really encourage people to take the third dose," she said.
She advised continuing to use masks for protection from infection.
"While vaccines are still protecting us from severe disease and hospitalization, the risk of long COVID conditions seems to increase with each infection. So it is not benign. We should not be too casual by saying that it is okay to get the infection.
"Many people just think that it is just like the flu or any other respiratory infection, but more and more data is coming out on how COVID is affecting all organ systems and not just the respiratory route. It also affects the cardiovascular system and the inflammatory environment. So we have seen the risk of diabetes doubling, we have seen the risk of heart attacks...and other neurocognitive problems," Dr Swaminathan added.

IPL first phase schedule announced amid travel concerns caused by war in West Asia
New Delhi (PTI): Defending champions Royal Challengers Bengaluru will take on Sunrisers Hyderabad in the IPL 2026 opener in Bengaluru on March 28 as the BCCI announced the first phase of the tournament schedule amid concerns around players' travel arrangements due to the ongoing West Asia conflict.
All matches scheduled at the Chinnaswamy Stadium remain subject to clearance from the Karnataka government appointed expert committee, which is scheduled to meet on March 13 to assess venue preparedness in the wake of the deadly stampede at the stadium last season.
The BCCI announced the schedule of the first 20 games on Wednesday and will unveil the full schedule once the dates of elections in three states -- Tamil Nadu, Assam and West Bengal -- are announced.
Besides the state elections, the escalating conflict in West Asia will also be at the forefront of BCCI officials' minds. The war has wreaked havoc to international travel with operations of major airports like Doha and Dubai being heavily restricted.
As a result of that, some of the squad members of South Africa and West Indies are yet to reach home a week after the completion of their T20 World Cup campaign.
It remains to be seen if IPL bound players of those two nations report to their respective teams in time.
"There was a substantial delay in departure of West Indies and South Africa players. It would be a tough task to get them back to India on time. Plus the airfares have gone up substantially due to the war in West Asia," a team official told PTI.
Additionally, hotels across India are facing cooking gas shortage due to the raging conflict and on Tuesday, the central government invoked Essential Commodities Act to ensure uninterrupted supply of domestic cooking gas.
Chennai Super Kings CEO Kasi Viswanthan told PTI that he is expecting his players from the West Indies and South Africa -- Akeal Hossein and Dewald Brevis, to join the team well before their IPL opener.
"We are expecting no delays from their end," he said.
The second game of the opening weekend will see Mumbai Indians host Kolkata Knight Riders at the Wankhede Stadium and the opening weekend will not feature any double-headers.
A total of 20 matches will be played across 10 venues: Bengaluru, Mumbai, Guwahati, New Chandigarh, Lucknow, Kolkata, Chennai, Delhi, Ahmedabad and Hyderabad.
"During the season, Royal Challengers Bengaluru will play five home matches in Bengaluru and two in Raipur. Punjab Kings will play four home matches in New Chandigarh and three in Dharamshala, while Rajasthan Royals will play three home matches in Guwahati and four in Jaipur," said the BCCI in a statement.
"During this period (the first 16 days), the tournament will feature four double-headers, with the afternoon matches beginning at 03:30 PM IST and the evening matches commencing at 07:30 PM IST.
"Following the opening encounter on Saturday, Mumbai Indians will take on Kolkata Knight Riders at the Wankhede Stadium in Mumbai on Sunday.
"The matches scheduled in Bengaluru are subject to clearance from the Expert Committee constituted by the Government of Karnataka," the BCCI added.
