Omicron BA.2 becomes dominant covid variant in India

New Delhi, Feb 23: A new sibling of the Omicron variant of SARS-CoV-2 has taken over the Indian Covid-19 landscape over the past month without altering the epidemic's waning course, even as the World Health Organization described it as a distinct variant of concern.

A technical advisory group of the WHO on Tuesday declared BA.2 sub-lineage of Omicron as a “variant of concern” on the basis of available data on transmission, severity, reinfection, diagnostics, therapeutics and impacts of vaccines.

“Studies have shown that BA.2 has a growth advantage over BA.1. Studies are ongoing to understand the reasons for this growth advantage, but initial data suggest that BA.2 appears inherently more transmissible than BA.1, which currently remains the most common Omicron sublineage reported,” the apex health body said.

But BA.2 has already become the dominant variant circulating in India.

Indian scientists monitoring the Covid-19 epidemic said more than 80 per cent of the Covid-19 positive samples sequenced in the past four weeks turned out to be BA.2.

In Pune, BA.2 was over 85 per cent by the last week of January, but cases continue to drop, suggesting protection from BA.1 infections and vaccination gave reasonable results in securing people from developing the disease, said a scientist associated with Covid genome sequencing work.

The WHO concurs. “Initial data from population-level reinfection studies suggest that infection with BA.1 provides strong protection against reinfection with BA.2, at least for the limited period for which data are available,” the UN body said.

The Pune scientist cautioned that it was preliminary evidence and the new variant needed to be observed closely.

BA.2 differs from BA.1 in its genetic sequence, including some amino acid differences in the spike protein and other proteins.

Omicron is currently the dominant variant circulating globally, accounting for nearly all sequences reported to GISAID, an international database of genetic sequences. At a global level, the proportion of BA.2 sequences has been increasing relative to BA.1 in recent weeks. However, the global circulation of all variants is declining, as per the WHO.

Mangaluru, Dec 15: Educational institutions in Mangaluru that rely on the popular Mangala Stadium for their annual sports events are bracing for an inconvenience as the city's key sporting venue is set to close its gates for a significant upgrade. The stadium is expected to be unavailable for approximately two months starting from January 15, 2026.

The closure is necessitated by a proposed overhaul of the stadium's facilities, with a special focus on upgrading the synthetic track. Pradeep Dsouza, Assistant Director of the District of Youth Empowerment and Sports (DYES), Dakshina Kannada, confirmed the development.

"Experts have visited the stadium, conducted a thorough inspection, and have given the go-ahead for a complete makeover," Dsouza stated. "Funds have been allocated for the project, and we are currently awaiting the final green signal from state officials to commence the work. We anticipate that the work will likely begin in the second week of January. Consequently, we have stopped renting out the stadium to colleges and other organizations in preparation for the upgrade."

The timing presents a logistical challenge for colleges, as many schools have already concluded their sports meets.

"Colleges will now be organizing their events and will need to find alternative locations to host their sports meets," Dsouza added. He suggested a few potential venues, including the Dakshina Kannada police ground, University College grounds, Panambur grounds, Swaraj Maidan in Moodbidri, and the Mangalore University sports grounds in Konaje.

However, many institutions note that finding a comparable venue will be difficult. While the DK police ground and University College grounds are closer to the city center, they do not possess the extensive facilities and infrastructure offered by Mangala Stadium.

Dr. P Dayananda Pai - P Satisha Govt First Grade College, Carstreet, is one such institution dependent on the stadium. Principal Jayakar Bhandary expressed hope for a swift completion of the work. "We expect the work to be completed at the earliest. If not, we will be forced to look for other venues to host the sports day for our students," Bhandary said, highlighting the pressing need for the city's main sporting facility.

Mangaluru, Dec 7: A rare bamboo shrimp has been rediscovered on mainland India more than 70 years after it was last reported, confirming for the first time the presence of Atyopsis spinipes in the country. The find was made by researchers from the Centre for Climate Change Studies at Sathyabama Institute of Science and Technology, Chennai, during surveys in Karnataka and Odisha.

The team — shrimp expert Dr S Prakash, PhD scholar K Kunjulakshmi, and Mangaluru-based researcher Maclean Antony Santos — combined field surveys, ecological assessments and DNA analysis to identify the elusive species. Their findings, published in Zootaxa, resolve decades of taxonomic confusion stemming from a 1951 report that misidentified the species as Atyopsis moluccensis without strong evidence.

The shrimp has now been confirmed at two locations: the Mulki–Pavanje estuary near Mangaluru and the Kuakhai River in Bhubaneswar. Historical specimens from the Andaman Islands, previously labelled as A. moluccensis, were also found to be misidentified and actually belong to A. spinipes.

The rediscovery began after an aquarium hobbyist in Odisha spotted a shrimp in 2022, prompting systematic surveys across Udupi, Karwar and Mangaluru. Four female specimens were collected in Mulki and one in Odisha, all genetically matching.

Researchers warn the species may exist in very small, vulnerable populations as freshwater habitats face increasing pressure from pollution, sand mining and infrastructure development. All verified specimens have been deposited with the Zoological Survey of India for future reference.

IndiGo, India’s largest airline, is battling one of its worst operational disruptions in recent years, with hundreds of delays and cancellations throwing domestic travel into chaos.

Government data on Tuesday showed its on-time performance plunging to 35%, an unusual dip for a carrier long associated with punctuality.

By Wednesday afternoon, airports in Delhi, Mumbai, Bengaluru and Hyderabad had collectively reported close to 200 cancellations, stranding travellers across the country.

Crew Shortage After New Duty Norms

A major trigger behind the meltdown is a severe crew shortage, especially among pilots, following the rollout of revised Flight Duty Time Limitation (FDTL) norms last month.

The rules mandate longer rest hours and more humane rosters — a shift IndiGo has struggled to incorporate across its vast network.

Sources said several flights were grounded due to lack of cabin crew, while some delays stretched upwards of eight hours.

With IndiGo controlling over 60% of India’s domestic aviation market, the ripple effect has impacted airports nationwide.

IndiGo Issues Apology, Lists “Compounding Factors”

In a statement, IndiGo acknowledged the large-scale disruption:

“We sincerely apologise to customers. A series of unforeseen operational challenges — technology glitches, winter schedule changes, adverse weather, system congestion and updated FDTL norms — created a compounding impact that could not have been anticipated.”

To stabilise operations, the airline has begun calibrated schedule adjustments for the next 48 hours, aiming to restore punctuality. Affected passengers are being offered refunds or alternate travel arrangements, IndiGo said.

What the FDTL Rules Require

The FDTL norms, designed to reduce pilot fatigue, cap duty and flying hours as follows:
•    Maximum 8 hours of flying per day
•    35 hours per week
•    125 hours per month
•    1,000 hours per year

Crew must also receive rest equalling twice the flight duration, with a minimum 10-hour rest period in any 24-hour window.

The DGCA introduced these limits to enhance flight safety.

Hyderabad: 33 Flights Cancelled, Long Queues Reported

Hyderabad’s Rajiv Gandhi International Airport saw heavy early-morning crowds as 33 IndiGo flights (arrivals and departures) were cancelled.

The airport clarified on X that operations were normal, advising passengers to contact IndiGo directly for latest flight status.

Cancellations included flights to and from Visakhapatnam, Goa, Ahmedabad, Delhi, Bengaluru, Chennai, Madurai, Hubli, Bhopal and Bhubaneswar.

Bengaluru: 42 Flights Disrupted

Bengaluru’s Kempegowda International Airport recorded 42 cancellations — 22 arrivals and 20 departures — affecting routes to Delhi, Mumbai, Chennai, Hyderabad, Goa, Kolkata and Lucknow.

Passengers Vent on Social Media

Irate travellers took to X to share their experiences. One passenger stranded in Hyderabad wrote: “I have been here since 3 a.m. and missed an important meeting.”

Another said: “My flight was pushed from 1:55 PM to 2:55 PM and now 4:35 PM. I was informed only three minutes before entering the airport.”

Delhi Airport Hit by Tech Glitch

At Delhi Airport, the disruption deepened due to a slowdown in the Amadeus system — used for reservations, check-ins and departure control.

The technical issue led to longer queues and sluggish processing, adding to delays already worsened by staff shortages.
