Continuing to monitor 'several descendent lineages' of Omicron variant: WHO
United Nations(PTI): The World Health Organisation has said that it is continuing to monitor several descendent lineages of the Omicron variant of the coronavirus, including two new sublineages that have additional mutations associated with potential "immune escape characteristics.
The COVID-19 Weekly Epidemiological Update, released by WHO on Tuesday, said that the Omicron variant remains the dominant variant circulating globally.
WHO said it continues to monitor several descendent lineages under the Omicron Variant of Concern, including BA.1, BA.2, BA.3 as well as now BA.4 and BA.5. It also includes BA.1/BA.2 circulating recombinant forms, such as XE.
A small number of sequences of BA.4 and BA.5 descendent lineages have now been detected in a few countries. Both have additional mutations in the Spike region (S:L452R, S:F486V) and unique mutations outside of Spike. The S:L452R and S:F486V mutations are associated with potential immune escape characteristics," the global health organisation said.
It added that it is working with scientists to further assess the characteristics of these lineages and their public health implications. WHO recommends countries to continue surveillance, where possible, and rapid data sharing on publicly available databases.
According to WHO, the SARS-CoV-2 virus continues to evolve. With such intense transmission worldwide, further variants, including recombinants, will emerge. This is expected."
WHO is tracking the two new sublineages (BA.4 and BA.5) as part of the Omicron variant.
These variants have additional mutations that need to be further studied to understand their impact on immune escape potential. Only a few dozen sequences of these variants have been reported from a handful of countries.
WHO is working with scientists to better understand their current spread as well as any potential impact they may have.
WHO said that Omicron's properties of immune escape have been associated with the rapid and almost synchronous increase in the global incidence of COVID-19 cases reported until the end of January 2022.
A further increase observed at the beginning of March was driven primarily by a delayed increase in case incidences in the Western Pacific Region and a rebound in the number of new cases reported in the European Region.
"This trend was likely due to a combination of factors, including the predominance of the Omicron Pango lineages BA.1, and then BA.2, with a transmission advantage over other Omicron lineages; relaxation of public health and social measures (PHSM); and waning of humoral immunity following vaccination and/or prior infection," it said.
"The recent detection of emerging recombinants of the Delta-Omicron and Omicron descendent lineages requires ongoing close monitoring.
The WHO update added that globally, during the week of April 4 through 10, the number of new COVID-19 cases and deaths has continued to decline for a third consecutive week, with over 7 million cases and over 22,000 deaths reported, a decrease of 24 per cent and 18 per cent respectively, as compared to the previous week.
All regions reported decreasing trends in the number of new weekly cases and deaths. As of April 10, over 496 million confirmed cases and over 6 million deaths have been reported globally.
These trends should be interpreted with caution as several countries are progressively changing their COVID-19 testing strategies, resulting in lower overall numbers of tests performed and consequently lower numbers of cases detected, it said.
Over 11 billion vaccine doses have been distributed globally. WHO however noted that substantial inequities remain, with only 11 per cent of those in low-income countries (LICs) having completed the primary series; and major differences among regions, with vaccination coverage ranging from 82 per cent in the Western Pacific Region to 13 per cent in the African Region.
There is particular concern about reaching the most vulnerable populations who remain unvaccinated, particularly those of older age and those with comorbidities, it said, adding that globally, an estimated 35 per cent of those aged 60 years and over are awaiting completion of the primary vaccination series.

EAM Jaishankar meets Jamaican PM, gifts over 10 BHISHM Cubes
Kingston (PTI): External Affairs Minister S Jaishankar on Monday met Jamaican Prime Minister Andrew Holness and discussed ways to further deepen "political, economic and people-to-people cooperation."
Jaishankar also conveyed greetings from Prime Minister Narendra Modi to Holness.
"Pleased to call on Prime Minister @AndrewHolnessJM in Kingston. Conveyed the greetings of PM @narendramodi," Jaishankar posted on X.
"Discussed deepening our political, economic and people-to-people cooperation. Value his commitment towards further strengthening India-Jamaica relations," the post further read.
Also, the external affairs minister handed over 10 BHISHM (Bharat Health Initiative for Sahyog Hita & Maitri) Cubes as a gift to Jamaica.
"Formally handed over 10 BHISHM Cubes as a gift from India to Jamaica, in the presence of PM @AndrewHolnessJM, Health Minister @christufton and FM @kaminajsmith," Jaishankar posted on X.
"The BHISHM Cube mobile hospital system, designed for rapid deployment, will help Jamaica during disasters and emergencies. The gift of these cubes is a statement of friendship, a commitment to disaster preparedness, and an outcome of innovation," the post said.
Jaishankar arrived in Kingston on Saturday evening, marking the first leg of his nine-day tour of Jamaica, Suriname, and Trinidad and Tobago, aimed at further strengthening India's strategic and cultural ties with the Caribbean nations.
Earlier in the day, he interacted with the Indian diaspora and discussed India's ongoing transformation in infrastructure, human development and technology-driven governance and entrepreneurship with them.
He also highlighted the cricket bond between both countries as India gifted a scoreboard to Jamaica.
A scoreboard was dedicated at Sabina Park in Kingston. It is the home of the Jamaica cricket team and is the only Test cricket ground in the Caribbean island nation.
The minister expressed hope that the new scoreboard would witness many memorable innings, including those symbolising the enduring friendship between the two countries.
Cricket has long been a strong cultural bridge between India and Jamaica, which is part of the West Indies cricket team.
Jamaican players, including Chris Gayle, Courtney Walsh and Michael Holding, have played a major role in shaping the legacy of West Indies cricket in the international arena, contributing to its dominance in earlier decades and its continued global appeal.
