Jerusalem, Aug 25: Wastewater containing coronaviruses, such as the one behind the Covid-19 pandemic, may be a potential threat, according to a new review of studies that calls for additional filtration steps in sewage treatment plants to successfully remove viruses.

The research, published in the journal Nature Sustainability, by an international collaboration of 35 researchers, assessed recent studies on coronaviruses in wastewater.

According to the review research, conventional wastewater treatment provides only partial removal of coronaviruses, with safe disposal or reuse depending on the effectiveness of final disinfection.

"There is ample reason to be concerned about how long coronaviruses survive in wastewater and how it impacts natural water sources," said study lead author Edo Bar-Zeev from the Ben-Gurion University of the Negev (BGU) in Israel.

"Can wastewater contain enough coronaviruses to infect people? The simple truth is that we do not know enough and that needs to be rectified as soon as possible," Bar-Zeev said.

According to the scientists, sewage leaking into natural watercourses might lead to infection with the novel coronavirus SARS-CoV-2 via airborne spray.

They said treated wastewater used to fill recreational water facilities, like lakes and rivers, could also become sources of contagion, adding that fruits and vegetables irrigated with this water may also be an indirect infection route.

The scientists recommended immediate, new research to determine the level of potential infection, if any, and how long coronaviruses last in various bodies of water and spray.

"Wastewater treatment plants need to upgrade their treatment protocols and in the near future also advance toward tertiary treatment through micro- and ultra-filtration membranes, which successfully remove viruses," the scientists noted.

They added that wastewater can also be used to monitor or track Covid-19 outbreaks.

Using a new methodology, the researchers recently detected and traced the presence of the novel coronavirus, and calculated its concentration to pinpoint emerging Covid-19 hotspots.

Angry outbursts, long queues, and desperate appeals filled airports across India today as IndiGo grappled with a severe operational breakdown. Hundreds of flights have been cancelled or delayed, leaving thousands of passengers stranded through the night and forcing many to spend long hours at helpdesks.

Social media was flooded with videos of fliers pleading for assistance, accusing the airline of misleading updates, and demanding accommodation after being stuck for 10 to 12 hours at airports such as Hyderabad and Bengaluru.

What Triggered the Meltdown?

IndiGo has attributed the widespread disruption to “a multitude of unforeseen operational challenges.” These include:

•    Minor technology glitches
•    Winter-season schedule adjustments
•    Bad weather
•    Congestion in the aviation network
•    New crew rostering rules (Flight Duty Time Limitations or FDTL)

Among these, the most disruptive has been the implementation of the updated FDTL norms introduced by the Directorate General of Civil Aviation (DGCA) in January 2024.

These rules were designed to reduce pilot fatigue and improve passenger safety. Key changes include:

•    Longer weekly rest periods for flight crew
•    A revised definition of “night,” extending it by an extra hour
•    Tighter caps on flight duty timing and night landings
•    Cutting night shifts for pilots and crew from six per roster cycle to just two

Once these norms became fully enforceable, airlines were required to overhaul rosters well in advance. For IndiGo, this triggered a sudden shortage of crew available for duty, leading to cascading delays and cancellations.

Why IndiGo Was Hit the Hardest

IndiGo is India’s largest airline by a wide margin, operating over 2,200 flights daily. That’s roughly double the number operated by Air India.

When an airline of this size experiences even a 10–20% disruption, it translates to 200–400 flights being delayed or grounded — producing massive spillover effects across the country.

IndiGo also relies heavily on high-frequency overnight operations, a model typical of low-cost carriers that aim to maximise aircraft utilisation and reduce downtime. The stricter FDTL norms clash with these overnight-heavy schedules, forcing the airline to pull back services.

Aviation bodies have also criticised IndiGo’s preparedness. The Airline Pilots' Association of India (ALPA) said airlines were given a two-year window to plan for the new rules but “started preparing rather late.” IndiGo, it said, failed to rebuild crew rosters 15 days in advance as required.

The Federation of Indian Pilots (FIP) went further, calling the crisis the result of IndiGo’s “prolonged and unorthodox lean manpower strategy,” and alleging that the airline adopted a hiring freeze even as it knew the new rules would require more careful staffing.

How Many Flights Are Affected?

In the past 48 hours, over 300 flights have been cancelled. At least 100 more are expected to be cancelled today.

City-wise impact:

•    Hyderabad: 33 expected cancellations; several fliers stranded overnight
•    Bengaluru: over 70 expected cancellations
•    Delhi, Mumbai, Chennai, Kolkata: widespread delays and missed connections

Passengers shared distressing accounts online.

One customer at Hyderabad airport said they waited from 6 PM to 9 AM with “no action taken” regarding their delayed Pune flight. Another said IndiGo repeatedly told them the crew was “arriving soon,” only for the delay to stretch over 12 hours.

IndiGo has apologised for the disruption and promised that operations will stabilise within 48 hours, adding that “calibrated adjustments” are being made to contain the chaos.

What Should Passengers Do Now?

For those flying in the next few days, especially with IndiGo, here are key precautions:

1. Keep Checking Flight Status
Monitor your flight closely before leaving for the airport, as delays may be announced last-minute.

2. Arrive Early
Expect long queues at counters and security due to crowding and rescheduling.

3. Carry Essentials
Pack snacks, water, basic medicines, chargers, and items for children or senior citizens. Extended waiting times should be anticipated.

4. Use Flexible Booking Options
If you booked tickets with a free-date-change or cancellation option, consider using them.
If you haven’t booked yet, prefer refundable or flexible fares, or even consider alternate airlines.

5. Follow IndiGo’s Updates
Keep an eye on IndiGo’s official social media channels and contact customer support for rebooking and refund queries.

What Needs to Change?

Pilot groups have raised concerns not just about staffing but also the planning practices behind it.
The Federation of Indian Pilots accused IndiGo of:

•    Imposing an unexplained hiring freeze despite knowing the FDTL changes were coming
•    Entering non-poaching agreements that limited talent movement
•    Keeping pilot pay frozen
•    Underestimating the need to restructure operations in advance

They have urged DGCA to approve seasonal schedules only after airlines prove they have adequate pilot strength under the new norms.

ALPA also warned that some airlines might be using the delays as an “immature pressure tactic” to push DGCA for relaxations in the new rules — which, if granted, could compromise the very safety standards the norms were meant to protect.

Both pilot bodies stressed that no exemption should dilute safety, and any deviations should be based solely on scientific risk assessment.

Is a Solution in Sight?

While IndiGo says normalcy will return within two days, aviation experts believe that fully stabilising operations could take longer, depending on how quickly the airline can:
•    Re-align rosters
•    Mobilise rested crew
•    Boost staffing
•    Adjust its winter schedule to match regulatory requirements
Passengers are advised to remain prepared for continued delays over the next few days as the airline works through its backlog.

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.”

Udupi district transformed into a sea of saffron and celebration on Friday, November 28, as Prime Minister Narendra Modi’s roadshow swept through the coastal temple town. Thousands of residents lined the streets, turning the event into a vibrant public spectacle filled with cheers, flags, and festive energy.

The procession route—from the helipad to the historic Sri Krishna Math—was decked with buntings, saffron flags, and multilayered security barricades. One of the district’s largest-ever security deployments was put in place for the high-profile visit, with over 3,000 police personnel on duty. The arrangement included ten SPs, 27 DSPs, 49 inspectors, 127 sub-inspectors, 232 assistant sub-inspectors, 1,608 constables, and 39 women staff.

Six platoons of the Karnataka State Reserve Police, six Quick Response Teams, bomb detection units, and dog squads were stationed across Udupi. Enhanced surveillance covered Adi Udupi, Bannanje bus stand, and the Sri Krishna Math parking zone, with combing operations carried out along the roadshow corridor.

At the 800-year-old Sri Krishna Math, preparations reached a ceremonial peak. Paryaya Puttige Math seer Sugunendra Teertha Swamiji said the Prime Minister would take part in the Laksha Kantha Geetha Parayana, a mass chanting of the Bhagavad Gita by one lakh devotees, and inaugurate the new Suvarna Teertha Mantapa.

“He will first offer floral tributes to saint-poet Kanakadasa and then unveil the golden covering over the Kanakana Kindi,” the seer said.

The Prime Minister will also receive a Poorna Kumbha welcome and have darshan of Lord Sri Krishna, Mukhyaprana Devaru, and the Suvarna Paduke. Union Minister Pralhad Joshi, Karnataka Governor Thaawarchand Gehlot, Minister Bairathi Suresh, Dharmadhikari D. Veerendra Heggade, and seers from the Ashta Maths are expected to join the ceremony.

Ahead of his arrival, the Prime Minister posted on X that he felt “honoured” to attend the spiritually significant gathering. “This is a special occasion that brings together people from different sections of society for a recital of the Gita. This Matha has a very special significance in our cultural life,” he wrote, noting the institution’s long-standing legacy rooted in the teachings of Sri Madhvacharya.
