AY.12, a sub-lineage of Delta which is driving fresh cases in Israel, is being seen in many states in the country but the numbers need a closer examination, INSACOG, a genome sequencing consortium, has said in its latest bulletin.
Breakthrough infections of coronavirus cases comprise a very high proportion of the Delta variant, the INSACOG, a genome sequencing government consortium of laboratories, has said.
It is the second death due to this variant in Maharashtra as it had claimed the life of an 80-year-old woman from Ratnagiri district on June 13.
Experts in Singapore, which is seeing a surge in Omicron cases, have warned that the new and supposedly more contagious variant is likely to replace Delta over the coming weeks as the dominant global variant, with the virus being fitter and having a reproductive advantage.
India has logged 123 new cases of Covid, while the number of active cases of the infection stood at 876, according to the Union Health Ministry's data updated on Tuesday.
'Delta continues to be the dominant lineage for new cases across all parts of India in recent samples and remains the most rapidly rising lineage globally that is responsible for multiple outbreaks, including across Southeast Asia, which shows the fastest growth in new cases globally,' the INSACOG said.
Bharat Biotech's Covaxin has demonstrated 77.8 per cent effectiveness against symptomatic COVID-19 and 65.2 per cent protection against the new Delta variant.
In the ensemble trial, Johnson & Johnson's vaccine was 85 per cent effective against severe/critical disease and demonstrated protection against hospitalisation and death. The vaccine was consistently effective across all regions studied globally, including in South Africa and Brazil, where there was a high prevalence of rapidly emerging Beta and Zeta variants during the study period.
The new order will impact cities like Nagpur, Thane and Pune as they had seen more relaxations than Mumbai, which continued to be under 'level 3' restrictions, despite qualifying for 'level 1' where all curbs are allowed to be lifted.
The Union health ministry on Friday urged eight states and Union Territories to take up immediate containment measures including preventing crowds, conducting widespread testing as well as increasing vaccine coverage on a priority basis in districts where the Delta Plus variant of coronavirus has been detected.
In view of cases of the Delta plus variant of COVID-19 emerging in Maharashtra, the state government on Friday announced 'state-level trigger' for imposing restrictions in administrative units irrespective of weekly positivity rate and oxygen bed occupancy percentage.
The Delta Plus variant have been detected sporadically in Maharashtra, Kerala and MP.
A nine-year-old lioness Neela and a male lion named Pathbanathan, aged 12 years, succumbed to COVID-19 earlier this month.
The highly virulent 'Delta plus' variant of the novel coronavirus could stoke a third wave in Maharashtra, according to a presentation made at a meeting attended by Chief Minister Uddhav Thackeray.
Researchers at Public Health Scotland and the University of Edinburgh, UK, found that the Pfizer-BioNTech vaccine offered better protection against the Delta variant compared to the Oxford-AstraZeneca preventive, known as Covishield in India.
The WHO's move came nearly three weeks after India objected to the B.1.617 mutant of the novel coronavirus being termed an 'Indian Variant' in media reports with the Union Health Ministry pointing out that the UN's top health organ has not used the word 'Indian' for this strain in its document.
"Omicron has been detected in all countries where we have good sequencing and it's likely to be in all countries around the world. It is quickly, in terms of its circulation, overtaking Delta. And so Omicron is becoming the dominant variant that is being detected," Kerkhove said during a virtual questions and answers session.
Lieutenant General Upendra Dwivedi, the general officer commanding-in-chief of the Northern Command, said five of the seven friction points in eastern Ladakh, where the Indian Army and the Chinese PLA are locked in a standoff since May 2020, have been resolved and talks are underway for the remaining areas.
The Delta variant is more transmissible than the viruses that cause MERS, SARS, Ebola, the common cold, the seasonal flu and smallpox, and it is as contagious as chickenpox, according to the document, a copy of which was also obtained by The New York Times.
'People who were vaccinated early on, for example, from January to April this year, namely health workers, the elderly, and the immunocompromised, should be identified for a booster dose.' 'We should start getting ready for administering booster doses to them on priority.'
'This means that there is a higher likelihood of individuals who have recovered from COVID-19 to be reinfected with the Omicron variant'
The study, which was conducted on more than 100 healthcare workers at three centres in India including Sir Ganga Ram Hospital, found that the B.1.617.2 Delta variant not only dominates vaccine-breakthrough infections with higher respiratory viral loads compared to non-Delta infections (Ct value of 16.5 versus 19) but also generates greater transmission among the fully vaccinated HCWs.
The Delta plus variant of COVID-19 has greater affinity to lung tissues as compared to other strains but it does not mean that it will cause severe disease or is more transmissible, head of coronavirus working group National Technical Advisory Group on Immunisation (NTAGI) Dr N K Arora said.
These 51 cases were detected from over 45,000 samples sequenced so far in the country.
The WHO said the four current 'Variants of Concern' being monitored closely - Alpha, Beta, Gamma and Delta - are widespread and have been detected in all WHO regions.
However, the "good news" is that the US vaccines are effective against the Delta variant, said Fauci, the head of the National Institutes of Allergy and Infectious Diseases.
The highly transmissible Delta variant of SARS-CoV-2 has mutated further to form the 'Delta plus' or 'AY.1' variant but there is no immediate cause for concern in India as its incidence in the country is still low, scientists in New Delhi said.
The Delta variant of COVID-19, or the B1.617.2 variant of concern (VOC) first identified in India, is about 60 per cent more transmissible than the Alpha strain identified in the United Kingdom and also reduces the effectiveness of vaccines to some extent, UK health experts report.
The rapid surge in cases during Delhi's fourth COVID-19 wave was mainly driven by the Delta variant, which likely has immune-evasion properties and counted for 60 per cent of the cases in April, according to a new study.
The study also shows that levels of these antibodies that are able to recognise and fight the virus are lower with increasing age, and that levels decline over time, providing additional evidence in support of plans to deliver a booster dose to vulnerable people.
SpiceJet's resurgence, once the new funding is in place, has the potential to disrupt the Indian aviation market in 2024 as the airline will bring its grounded aircraft back to service and lease as many planes as possible to be competitively relevant, aviation consultancy firm Capa India said on Thursday. "Although the market for procuring aircraft in 2024 is exceptionally tight, we expect that SpiceJet will bring stored aircraft back into operations, and will wet or dry lease as much capacity as possible, in order to be competitively relevant. "This will have a material impact on the industry structure, and possibly on domestic profitability," Capa India said in its report.
The international team of researchers combined lab-based experiments and epidemiology of vaccine breakthrough infections, showing that the Delta variant is better at replicating and spreading than other commonly-observed variants.

A total of 1,226 cases of COVID-19 sub-variant JN.1 have been reported in the country so far with Karnataka and Andhra Pradesh recording the highest number of cases till now, according to the Indian SARS-CoV-2 Genomics Consortium (INSACOG) on Thursday.
The researchers analysed 2580,021 test results from nose and throat swabs taken from 384,543 participants aged 18 years or older between December 1, 2020 and May 16, 2021.
The NIH said results of two studies of blood serum from people who had received Covaxin suggest that the vaccine generates antibodies that effectively neutralise the B.1.1.7 (Alpha) and B.1.617 (Delta) variants of SARS-CoV-2, first identified in the United Kingdom and India, respectively.
It will be unfair to put a date for any COVID wave as the behaviour of coronavirus is unpredictable and a disciplined and effective pandemic response can help the country get away from any significant outbreak, COVID Task Force chief V K Paul said.
22 cases of the Delta Plus variant of the coronavirus have been detected in India, with 16 of them being reported from Maharashtra and the remaining from Madhya Pradesh and Kerala, the government said.
Nearly 90 per cent of the stocks comprising the National Stock Exchange Nifty 500 Index and 49 of the 50 stocks that make up the Nifty50 are trading above their respective 200-day moving averages (DMAs). The 200-DMA is considered one of the most relevant trend indicators by investors and traders. They believe that stocks and indices trading above this key level exhibit strength and are likely to rally, while those trading below this level are viewed as bearish, with the stock/index expected to see a selloff.
As of July 13, at least 111 countries, territories and areas have reported detection of the Delta variant, and this is expected to continue to increase, becoming the dominant variant globally in the coming months.
