New covid-19 variant 'Delta plus' identified; Should India be worried?

Agencies
June 14, 2021

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 said.

The new Delta plus variant has been formed due to a mutation in the Delta or B.1.617.2 variant, first identified in India and one of the drivers of the deadly second wave. Though there is no indication yet of the severity of the disease due to the new variant, Delta plus is resistant to the monoclonal antibody cocktail treatment for Covid-19 recently authorised in India.

“One of the emerging variants is B.1.617.2.1 also known as AY.1 characterized by the acquisition of K417N mutation,” Vinod Scaria, clinician and scientist at Delhi’s CSIR-Institute of Genomics and Integrative Biology (IGIB), tweeted on Sunday.  

The mutation, he said, is in the spike protein of SARS-COV-2, which helps the virus enter and infect the human cells.  

According to Public Health England, 63 genomes of Delta (B.1.617.2) with the new K417N mutation have been identified so far on the global science initiative GISAID.  

In its latest report on coronavirus variants, updated till last Friday, the health agency said Delta plus was present in six genomes from India as of June 7.  

“The variant frequency for K417N is not much in India at this point in time. The sequences are mostly from Europe, Asia and America,” Scaria wrote on Twitter.  

The earliest sequence of this genome was found in Europe in late March this year.  

Noting that the travel histories for the variant are not readily available to make assumptions, Scaria said an important point to consider regarding K417N is the “evidence suggesting resistance to monoclonal antibodies Casirivimab and Imdevimab”.

This cocktail recently received emergency-use authorization in the country from the Central Drugs Standard Control Organisation. Drug majors Roche India and Ciplas have priced the antibody cocktail at a steep Rs 59,750 per dose.  

Similar to antibodies which are proteins that the body naturally produces to defend itself against the disease, monoclonal antibodies are artificially created in a lab and tailor-made to fight the disease they treat.  

Casirivimab and Imdevimab are monoclonal antibodies that are specifically directed against the spike protein of SARS-CoV-2, and designed to block the virus' attachment and entry into human cells.  

Scaria also indicated the mutation may be associated with the ability to escape the immune response against the virus.

Allaying fears, immunologist Vineeta Bal noted that while there may be some setback in the use of commercial antibody cocktail due to the new variant, resistance to the therapy is not an indication of higher virulence or severity of a disease.  

“How transmissible this new variant is will be a crucial factor to determine its rapid spread or otherwise,” Bal, guest faculty at the Indian Institute of Science Education and Research, Pune, told PTI.  

She also noted that the quality and quantity of neutralising antibodies, responsible for defending cells from pathogens, generated in the individual infected with the new variant is unlikely to be affected because of the mutation.  

“Thus in individuals catching infection with the new variant, it may not be a matter worth worrying,” she added. 

Pulmonologist and medical researcher Anurag Agrawal concurred.  

“There is no cause of concern due to the new variant in India as of now,” Agrawal, the director of CSIR-IGIB, told PTI.

The scientist said the blood plasma from many fully vaccinated individuals will have to be tested against this variant to determine whether it shows any significant immune escape.  As the Delta variant continues to evolve and acquire new mutations, there is a lot of interest in understanding its evolution. He said SARS-CoV-2 has a nearly constant rate of acquiring genetic variants, and each variant has acquired additional variants in a stepwise fashion.

“Understanding this continued evolution is of great importance in mapping the evolutionary landscape of emerging variants. Largely the virus has tried to optimise for transmission and immune escape by step-wise acquisition of new mutations,” he added

The Palestinian Hamas resistance movement says its fighters have killed at least 20 Israeli soldiers in northern parts of the besieged Gaza Strip in just two days, in retaliation for the occupying regime’s genocidal war on the Palestinian territory.

In a statement on Monday evening, Hamas said that fighters of its military wing, al-Qassam Brigades, “killed at least five occupation soldiers” in northern parts of the coastal territory earlier in the day.

It added that Hamas fighters also killed 15 Israeli soldiers in the war-ravaged region on Sunday.

The resistance movement’s “qualitative operation … confirms once again the failure of the criminal Zionist entity to suppress and eradicate the Palestinian resistance, which continues to direct qualitative strikes against its terrorist soldiers,” Hamas further said on its Telegram channel.

Palestinians have increased their resistance operations in the face of intensified Israeli aggression in northern Gaza that has claimed the lives of more than 1,000 over the past weeks.

“Our valiant resistance is waging a war of attrition with the criminal enemy, inflicting daily losses on its soldiers and vehicles, and all of [Israeli prime minister Benjamin] Netanyahu’s bets and dreams of achieving any of his goals are failing,” the Gaza-based resistance movement added.

Hamas also vowed that Israel’s ongoing crimes and aggression against Gaza would be met with increased resistance and painful strikes, which will continue until the aggression against Palestinians ends and the regime fully withdraws from the blockaded territory.

As the war in Gaza enters its 14th month, the Health Ministry reports that Israeli attacks have killed at least 43,603 Palestinians and wounded 102,929 others.

The media office in the Gaza Strip, where the Israeli regime has been waging a genocidal war since last October, says as many as 188 Palestinian journalists have been killed since the onset of the brutal military onslaught.

The office provided the figure on Saturday, naming four journalists as the most recent victims of the onslaught.

It identified the foursome as Zahraa Mohammad Abu Sukheil, Ahmad Mohammad Abu Sukheil, Mustafa Khadr Bahar, and Abdel Rahman Khadr Bahar.

The office said it “strongly condemns the targeting, killing, and assassination of Palestinian journalists by the Israeli occupation and holds it fully responsible for committing this heinous crime.”

“We call on the international community, international organizations, and those involved in journalistic work worldwide to take action against the occupation, pursue it in international courts for its ongoing crimes, and pressure it to halt the genocide and the targeted killings of Palestinian journalists,” it said.

Earlier in the day, the office said the Israeli regime had bombed the tents sheltering journalists and displaced persons at the al-Aqsa Martyrs' Hospital in the city of Deir al-Balah in central Gaza for the ninth consecutive time.

The atrocity that claimed the lives of two people and injured 26 others came as part of “the genocidal crimes committed by the Israeli occupation army against hospitals, civilians, and displaced persons,” it said.

The media office held the regime and the United States, its biggest ally, as well as other countries aiding the genocide fully responsible for such systematic crimes.

At least 43,552 Palestinians, mostly women and children, have been killed and 102,765 others wounded since the launch of the war that followed a retaliatory operation by Gaza’s resistance groups.

The fatalities include 44 people, who were killed across the coastal sliver, in the most recent phase of the military onslaught.

As many as 24 of the victims were killed in the northern part of the territory, where the regime has markedly intensified its deadly attacks for weeks.

They included an eight-year-old child and a five-year-old one, who lost their lives after Israeli warplanes targeted a group of minors filling up jerry cans with water alongside their mother at the Jabalia Refugee camp.

Gaza’s heath ministry, meanwhile, said a number of victims remained under the rubble and in the streets following Israeli airstrikes, saying ambulances and civil defense teams could not reach them due to the sheer extent of the destruction caused by the raids and obstruction caused by the regime.

Also on Saturday, the Integrated Food Security Phase Classification (IPC) report, a United Nations-backed assessment, warned that famine was looming in northern Gaza amid escalated Israeli aggression and the regime’s near-total siege of the targeted areas.

The alert from the Famine Review Committee warned of "an imminent and substantial likelihood of famine occurring, due to the rapidly deteriorating situation in the Gaza Strip."

On October 17, the body projected that the number of people in Gaza facing "catastrophic" food insecurity between November and April 2025 would reach 345,000, or 16 percent of the population.

The IPC report classified that figure as Phase 5 -- a situation when "starvation, death, destitution, and extremely critical acute malnutrition levels are evident."

The Israeli military, however, questioned the report's credibility.

"To date, all assessments by the IPC have proven incorrect and inconsistent with the situation on the ground," the army said in a statement, denouncing "partial, biased data and superficial sources with vested interests."
