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.

Israel launches first airstrike on Lebanon since ceasefire, accusing Hezbollah of breaching truce
Beirut, Nov 28: The Israeli military on Thursday said its warplanes fired on southern Lebanon after detecting Hezbollah activity at a rocket storage facility, the first Israeli airstrike a day after a ceasefire between Israel and Hezbollah took hold.
There was no immediate word on casualties from Israel's aerial attack, which came hours after the Israeli military said it fired on people trying to return to certain areas in southern Lebanon. Israel said they were violating the ceasefire agreement, without providing details. Lebanon's state-run National News Agency said two people were wounded.
The back-to-back incidents stirred unease about the agreement, brokered by the United States and France, which includes an initial two-month ceasefire in which Hezbollah members are to withdraw north of the Litani River and Israeli forces are to return to their side of the border. The buffer zone would be patrolled by Lebanese troops and UN peacekeepers.
On Thursday, the second day of a ceasefire after more than a year of bloody conflict between Israel and Hezbollah, Lebanon's state news agency reported that Israeli fire targeted civilians in Markaba, close to the border, without providing further details. Israel said it fired artillery in three other locations near the border. There were no immediate reports of casualties.
An Associated Press reporter in northern Israel near the border heard Israeli drones buzzing overhead and the sound of artillery strikes from the Lebanese side.
The Israeli military said in a statement that “several suspects were identified arriving with vehicles to a number of areas in southern Lebanon, breaching the conditions of the ceasefire.” It said troops “opened fire toward them” and would “actively enforce violations of the ceasefire agreement.”
Israeli officials have said forces will be withdrawn gradually as it ensures that the agreement is being enforced. Israel has warned people not to return to areas where troops are deployed, and says it reserves the right to strike Hezbollah if it violates the terms of the truce.
A Lebanese military official said Lebanese troops would gradually deploy in the south as Israeli troops withdraw. The official spoke on condition of anonymity because they were not authorized to brief media.
The ceasefire agreement announced late Tuesday ended 14 months of conflict between Israel and Hezbollah that began a day after Hamas' Oct. 7, 2023 attack out of Gaza, when the Lebanese Hezbollah group began firing rockets, drones and missiles in solidarity.
Israel retaliated with airstrikes, and the conflict steadily intensified for nearly a year before boiling over into all-out war in mid-September. The war in Gaza is still raging with no end in sight.
More than 3,760 people were killed by Israeli fire in Lebanon during the conflict, many of them civilians, according to Lebanese health officials. The fighting killed more than 70 people in Israel — over half of them civilians — as well as dozens of Israeli soldiers fighting in southern Lebanon.
Some 1.2 million people were displaced in Lebanon, and thousands began streaming back to their homes on Wednesday despite warnings from the Lebanese military and the Israeli army to stay out of certain areas. Some 50,000 people were displaced on the Israeli side, but few have returned and the communities near the northern border are still largely deserted.
In Menara, an Israeli community on the border with views into Lebanon, around three quarters of homes are damaged, some with collapsed roofs and burnt-out interiors. A few residents could be seen gathering their belongings on Thursday before leaving again.
