The Delta variant, the significantly more transmissible strain of Covid-19, is expected to become a “dominant lineage” if current trends continue, the WHO has warned after it was reported in 85 countries and continues to be detected in more places around the world.

The Covid-19 Weekly Epidemiological Update released on June 22 by the World Health Organisation (WHO) said that globally, the variant Alpha has been reported in 170 countries, territories or areas, Beta in 119 countries, Gamma in 71 countries and Delta in 85 countries.

“Delta, now reported in 85 countries globally, continues to be reported in new countries across all WHO Regions, 11 of which were newly reported in the past two weeks,” the update said.

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.

“The Delta variant is significantly more transmissible than Alpha variant, and is expected to become a dominant lineage if current trends continue.”

The update said that India reported the highest numbers of new Covid19 cases, 441,976 over the past week (June 14-20, 2021), a 30 per cent decrease as compared to the previous week. The highest numbers of new deaths were reported from India (16,329 new deaths; 1.2 new deaths per 100,000; a 31 per cent decrease).

The South-East Asia Region reported over 600,000 new cases and over 19,000 new deaths, a 21 per cent and a 26 per cent decrease respectively compared to the previous week.

“Decreasing trends in weekly case and death incidence in the Region are predominantly associated with decreases reported in India,” the update said.

WHO noted that since the last detailed update on June 8, new evidence has been published on the phenotypic characteristics of the Delta variant. “A study from Singapore showed that infection with Delta variant was associated with higher odds of oxygen requirement, intensive care unit (ICU) admission, or death,” it said.

Further, a study in Japan "estimating the relative instantaneous reproductive number (a measure of transmission at a specific point in time) showed that the Delta variant was associated with greater transmissibility" when compared to the Alpha variant.

“When compared with the variants circulating in Japan before December 2020, the relative instantaneous reproduction number for Alpha was estimated to be at 1.56 and for Delta 1.78. Overall, this study showed Delta was associated with 1.23 times higher transmissibility than Alpha,” the update said.

The update also took note of two studies that have provided evidence of the effectiveness of Pfizer BioNTech-Comirnaty and AstraZeneca-Vaxzevria vaccines against the Delta variant. One study reports on the effectiveness of these vaccines against severe disease (hospitalisation) due to Delta among persons over the age of 16 years in the United Kingdom.

Vaccine effectiveness estimates against hospitalisation due to Delta and Alpha variants over 14 days post second dose was estimated to be 96 per cent and 95 per cent respectively for Pfizer BioNTech- Comirnaty and 92 per cent and 86 per cent respectively, for AstraZeneca-Vaxzevria.

Single dose effectiveness against hospitalisation over 21 days after immunisation remained high for Pfizer BioNTech-Comirnaty at 94 per cent against Delta and 83 per cent against Alpha. Effectiveness of one dose of AstraZeneca-Vaxzevria against hospitalization was similar for Delta and Alpha variants.

A second study from Scotland found that two doses of Pfizer BioNTech-Comirnaty were 83 per cent and 79 per cent effective against symptomatic disease and infection due to Delta, respectively, over 14 days after receipt of second dose in persons 15 years and older.

“Together, these studies suggest moderately reduced VE at preventing symptomatic disease and infection due to the Delta variant as compared to Alpha...The studies also provide further evidence of the importance of two doses of both Pfizer BioNTech-Comirnaty and AstraZeneca-Vaxzevria in preventing hospitalisation, symptomatic disease and infection due to both Delta and Alpha variants,” the update said.

New Delhi: Karnataka chief minister Siddaramaiah and deputy CM DK Shivakumar on Saturday put up a dramatic display of unity at a closely watched joint press briefing, firmly dismissing weeks of speculation about a power-sharing tussle within the Congress. With the high command nudging both leaders to sit together and settle the dust, the meeting became a political spectacle, ending with the duo declaring that there was “no confusion, no differences.”

Calling the reports of a rift “manufactured confusion,” Siddaramaiah said the talks had gone smoothly, even joking about their breakfast. “Breakfast was very good. All three of us enjoyed it,” he said. “We want to end this confusion once and for all. For local elections and for 2028, our mission is clear — Congress must return to power. There is no difference between me and DKS, not now, not before.”

He blamed the media for fuelling rumours and reiterated absolute adherence to the party leadership. “From tomorrow, let there be no confusion. What the high command says, we will follow.”

Siddaramaiah also assured that the Assembly session starting December 8 would run smoothly and vowed that Congress would take on the BJP and JD(S) “together.”

Shivakumar echoed the chief minister word for word, stressing loyalty and discipline. “People have given us a massive mandate. It is our duty to deliver,” he said. “This government was formed under Siddaramaiah’s leadership. We both have complete trust in the high command. If they tell me to wait, I will wait.”

He added that the two leaders had discussed strategy for the 2028 Assembly elections. “Whatever the CM says, I agree. We are loyal soldiers of the party. The party may be facing challenges nationally, but we will keep it strong in Karnataka.”

Shivakumar also said Siddaramaiah would soon visit his home for lunch or dinner — another symbolic gesture meant to underline their unity.

Both leaders later posted on social media describing the breakfast meeting as “productive” and focused on “Karnataka’s priorities.”

The BJP, however, rejected the show of camaraderie as “pure bunkum,” accusing Congress of trying to paper over an internal power struggle. But Siddaramaiah and Shivakumar insisted their united front would continue — and that there was “no confusion” within the state leadership.

Bengaluru: The Vokkaligara Sangha on Thursday issued a stern warning to the Congress, saying the party could face serious electoral repercussions if Deputy Chief Minister D.K. Shivakumar is not appointed as Chief Minister.

The warning follows the public backing of Shivakumar’s chief ministerial ambition by top Vokkaliga pontiff Nirmalanandanatha Swami, who urged the Congress high command to honor his claim.

“The community supported Congress in the 2023 Assembly elections only because Shivakumar had a real chance to become CM. If he is cheated, we’ll teach the party a big lesson,” said newly elected Sangha president L. Srinivas. He added that Vokkaligas would organize protests under the guidance of community leaders.

General Secretary C.G. Gangadhar pointed out that Congress won more seats in the Vokkaliga-dominated Old Mysuru region due to Shivakumar’s influence, adding, “If Congress wants to retain power, Shivakumar should be made the CM.”

Outgoing president Kenchappa Gowda emphasized Shivakumar’s contribution to Congress’ victory. “Our community voted for Congress thinking he would become CM. Siddaramaiah has also served the party well, but Shivakumar should now be given a chance,” he said.

Former general-secretary Konappa Reddy appealed to Sonia and Rahul Gandhi to recognize Shivakumar’s loyalty and service, saying, “Congress is known to keep its promises. We hope it won’t break the promise made to him.”

Mangaluru: Chaos erupted at Mangaluru International Airport (MIA) after IndiGo flight 6E 5150, bound for Mumbai, was repeatedly delayed and ultimately cancelled, leaving around 100 passengers stranded overnight. The incident highlights the ongoing country-wide operational disruptions affecting the airline, largely due to the implementation of new Flight Duty Time Limitations (FDTL) norms for crew.

The flight was initially scheduled for 9:25 PM on Tuesday but was first postponed to 11:40 PM, then midnight, before being cancelled around 3:00 AM. Passengers expressed frustration over last-minute communication and the lack of clarity, with elderly and ailing travellers particularly affected. “Though the airline arranged food, there was no proper communication, leaving us confused,” said one family member.

An IndiGo executive at MIA cited the FDTL rules, designed to prevent pilot fatigue by limiting crew working hours, as the cause of the cancellation. While alternative arrangements, including hotel stays, were offered, about 100 passengers chose to remain at the airport, creating tension. A replacement flight was arranged but also faced delays due to the same constraints, finally departing for Mumbai around 1:45 PM on Wednesday. Passengers either flew, requested refunds, or postponed their travel.

The Mangaluru delay is part of a broader crisis for IndiGo. The airline has been forced to make “calibrated schedule adjustments”—a euphemism for widespread cancellations and delays—after stricter FDTL norms came into effect on November 1.

While an IndiGo spokesperson acknowledged unavoidable flight disruptions due to technology issues, operational requirements, and the updated crew rostering rules, the DGCA has intervened, summoning senior airline officials to explain the chaos and outline corrective measures.

The ripple effect has been felt across the country, with major hubs like Bengaluru and Mumbai reporting numerous cancellations. The Mangaluru incident underscores the systemic operational strain currently confronting India’s largest carrier, leaving passengers nationwide grappling with uncertainty and delays.
