SYDNEY / MANILA / HANOI / SINGAPORE / YANGON / VIENTIANE / SEOUL / WELLINGTON / NEW DELHI / KUALA LUMPUR / ISLAMABAD - The Omicron sub-variant XBB, particularly XBB.3, is likely to be the dominant strain of the COVID-19 virus in India within a month, reported The Times of India newspaper on Tuesday citing scientists.
According to the report, there were 71 confirmed cases of XBB-driven COVID-19 infection in India in the beginning of this month, and the number jumped to 136 by Oct. 23. "On Monday the case count was 235," it added.
It quoted a senior scientist with the Indian SARS-CoV-2 Genomics Consortium (INSACOG) as saying that the XBB.3 strain is currently leading the pack in India "with maximum cases."
According to the report, the eastern state of West Bengal has reported the highest number of such infections, at 103, in the South Asian country.
"Authorities have called for caution. In Maharashtra the health department has warned that a possible XBB-led spike may peak by mid-November," added the report.
According to a member of the national COVID-19 task force Dr. Sanjay Pujari, the genomic surveillance must continue. "Impact of these sub-variants on illness severity needs to be explored and (COVID-19 vaccine) booster uptake, at least for those at higher risk, needs to improve," he added.
The XBB variant was first detected in August and the World Health Organization has described it as among the most immune-evasive versions of the COVID-19 virus yet. It is being closely monitored by countries in the Asia-Pacific region.

Meanwhile, India's daily COVID-19 caseload Tuesday fell below the 1,000 mark, officials said.
According to federal health ministry data released on Tuesday morning, 862 new cases of COVID-19 were reported during the past 24 hours in the South Asian country, taking the total tally to 44,644,938.
The cases reported on Tuesday mark a decrease in comparison to the daily caseload of 1,334 on Monday.
The country also logged three new COVID-19 related deaths during the past 24 hours, taking the death toll to 528,980 since the beginning of the pandemic, the ministry said.

About 100 people on board Coral Princess, the first large international cruiser to enter the waters of the state of Western Australia (WA) in two years, tested positive for COVID-19, local media reported.
The cruise ship, which has the capacity of carrying nearly 2,000 passengers, was scheduled to stop at several coastal regions of the state before returning to Sydney next month.
A WA Health spokesperson said the passengers and crew aboard the vessel had tested positive for COVID-19, the national broadcaster ABC news reported late on Monday.
"WA Health has been advised of passengers and crew testing positive for COVID-19, and this evolving situation is being managed by the vessel operator according to its COVID-19 plan," the spokesperson said.
Local newspaper the Western Australian said it is believed there are up to 100 cases of COVID-19 aboard.
Western Australia allowed large international cruise liners to return to some port destinations from Oct 1 after the federal government lifted the ban on international large cruise ships in April.
But all cruise ships operating in WA are required to have a COVID-19 management plan in place, and crew and passengers will be required to be double dose vaccinated and have received a third dose, if eligible.
Under the state's current COVID-19 protocols, those who tested positive for the virus are recommended to isolate for a minimum of five days.
ABC news said a spokesperson for the company operating the vessel said a rise in COVID-19 cases aboard was being "managed effectively" in accordance with national and state protocols.

In another development, immunoglobulin A (IgA) contributed to the neutralizing antibody response of wild-type COVID-19 virus, according to an Australian study published in the Clinical and Translational Immunology journal.
Conducted by researchers from Australia's Peter Doherty Institute for Infection and Immunity (Doherty Institute), the University of Melbourne and Walter and Eliza Hall Institute of Medical Research, the study published on Sunday compared different antibody responses to the virus in blood serum from 41 people who had recovered from COVID-19.
"In simple terms, we've deconstructed blood in our lab to measure its ability to smother the virus and to activate immune cells to kill SARS-CoV-2," said Samantha Davis, lead author and PhD researcher at the Doherty Institute.
"While we knew that IgG (Immunoglobulin G) is very important in the antibody response to clear the virus, we discovered that IgA also plays a key role in neutralizing it in most people," Davis noted.
According to a statement by the Doherty Institute on Monday, following COVID-19 infection, virus-specific antibodies are generated, which can both neutralize the virus and clear the infection. While much has been said about the importance of IgG antibodies for protection and control of the COVID-19 virus, the role of IgA antibodies has been relatively neglected throughout the pandemic.
Amy Chung, co-author and laboratory head of the Doherty Institute, said the new study opened door to new approaches for the development of future vaccines against COVID-19.
"Our findings are particularly important as IgA is the most abundant antibody present in the mucosa of our respiratory tract, which is the main route of virus infection," said Chung. "This means if we're able to specifically make these antibodies at these vulnerable sites, we now know that we can induce a robust immune response to protect against the virus."
Researchers also pointed out that the convalescent IgA neutralizing response is highly heterogenous between individuals. Dissecting the IgA response in the context of vaccination and to variants of concern is essential to further understanding the antibody in a protective polyclonal antibody response, according to the study.

The Lao Health Ministry called on people to get a booster shot of COVID-19 to strengthen their immunity as there is a high risk of a further outbreak.
Head of the Vaccine Preventable Disease Division under the ministry Kongxay Phounphenghack told a press conference in the Lao capital Vientiane on Monday that many people are reluctant to have a third dose of a COVID-19 vaccine because they believe it is unnecessary.
However, a booster vaccination offers significant added protection against the virus, he added.
The health authorities are warning everyone in Laos to be alert as there is a high risk of a further outbreak, given that a large number of Lao workers are returning from other countries, where COVID-19 infections are spiraling.
Statistics show that at least 15 percent of returning workers are carrying the virus. This poses the threat of a widespread outbreak in Laos, said Kongxay.
The health authorities are expediting the vaccination program as Laos strives to prevent a further outbreak of the virus.
