‘For each covid case detected in India, 30 were missed or undetected’

For every single Covid-19 case reported in India, there were 30 cases that remained undetected or were missed, according to an analysis of ICMR's fourth sero-survey by independent epidemiologist Dr Chandrakant Lahariya.

The public health expert shared his analysis on Twitter in which he showed for every reported Covid-19 case in India, how many cases were missed.

He, however, clarified that it does not mean this was deliberate but simply reflects the performance of the disease surveillance system and the response to pandemic in the state in tackling the cases.

"Many cases are asymptomatic so they are likely to go unreported. If contact tracing is done well, even asymptomatic cases can also be reported. This has been reflected in the fact that a few states have done better than others as they can report on more cases as compared to other states," Lahariya said.

The Union health ministry on Wednesday shared the findings of the fourth round of national serosurvey conducted by ICMR across 70 districts of India.

While Madhya Pradesh leads the chart with 79 per cent seroprevalence, Kerala is at the lowest with 44.4 per cent followed by Assam with 50.3 per cent and Maharashtra with 58 per cent.

For every laboratory confirmed Covid-19 cases in India, the number of unreported or undetected cases ranged from 6 to 98, according to the analysis.

Among states and union territories, the analysis by Lahariya showed that Uttar Pradesh missed the highest number of cases. With every case reported in that state, 98 cases were missed or remained undetected.

The under-counting factor was lowest for Kerala at 6 which means for every case reported six cases were missed, according to the analysis.

The under-counting factor for India was 30 which means for every case reported 30 cases were missed, according to the analysis.

For Madhya Pradesh, the under-counting factor was 83 - highest after Uttar Pradesh followed by Jharkhand at 63, Rajasthan at 62, Gujarat at 61 and Bihar at 59.

Speaking about the analysis, Lahariya said, "What we need to remember is that sampling of sero survey has been done in a scientific manner from 21 states and UTs so we know India has 67.6 per cent seropositivity at national level which is undisputed and the government says it so this essentially means there are 90-95 crore people in India who are sero-positive and a majority after natural infection. So they will come in the same proportion from states through which we have arrived at this conclusion."

In immunology, seroconversion is the development of specific antibodies in the blood serum as a result of infection or immunization.

However, Lahariya said that a state and district specific survey will provide a more accurate picture and the government should urgently plan such a survey.

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.

New York/Washington: US President Donald Trump has again claimed to have solved the conflict between India and Pakistan, repeating his assertion during a meeting with New York City Mayor-elect Zohran Mamdani in the Oval Office.

Mamdani flew to Washington DC for his first meeting with Trump in the White House on Friday. Trump said he “enjoyed” the meeting, which he described as “great.”

During remarks in the Oval Office, with Mamdani standing next to him, Trump repeated his claim that he solved the May conflict between India and Pakistan.

"I did eight peace deals of countries, including India and Pakistan,” he said.

On Wednesday, Trump had said he threatened to put 350 per cent tariffs on India and Pakistan if they did not end their conflict, repeating his claim that he solved the fighting between the nuclear-armed neighbours and that Prime Minister Narendra Modi had called him to say “we're not going to go to war.”

Since May 10, when Trump announced on social media that India and Pakistan had agreed to a “full and immediate” ceasefire after a “long night” of talks mediated by Washington, he has repeated his claim over 60 times that he “helped settle” the tensions between India and Pakistan.

India has consistently denied any third-party intervention. India launched Operation Sindoor on May 7, targeting terror infrastructure in Pakistan and Pakistan-occupied Kashmir in retaliation for the April 22 Pahalgam attack that killed 26 civilians. India and Pakistan reached an understanding on May 10 to end the conflict after four days of intense cross-border drone and missile strikes.

Mamdani emerged victorious in the closely-watched battle for New York City Mayor, becoming the first South Asian and Muslim to be elected to sit at the helm of the largest city in the US.

He had been the front-runner in the NYC Mayoral election for months and defeated Republican nominee Curtis Sliwa and political heavyweight former New York State Governor Andrew Cuomo, who ran as an independent candidate and was officially endorsed by Trump just hours before the elections.

Indian-descent Mamdani is the son of renowned filmmaker Mira Nair and Columbia University professor Mahmood Mamdani. He was born and raised in Kampala, Uganda and moved to New York City with his family when he was 7. Mamdani became a naturalised US citizen only recently, in 2018.

New Delhi: IndiGo, India’s largest airline, faced major operational turbulence this week after failing to prepare for new pilot-fatigue regulations issued by the Directorate General of Civil Aviation (DGCA). The stricter rules—designed to improve flight safety—took effect in phases through 2024, with the latest implementation on November 1. IndiGo has acknowledged that inadequate roster planning led to widespread cancellations and delays.

Below are the key DGCA rules that affected IndiGo’s operations:

1. Longer Mandatory Weekly Rest

Weekly rest for pilots has been increased from 36 hours to 48 hours.

The government says the extended break is essential to curb cumulative fatigue. This rule remains in force despite the current crisis.

2. Cap on Night Landings

Pilots can now perform only two night landings per week—a steep reduction from the earlier limit of six.

Night hours, defined as midnight to early morning, are considered the least alert period for pilots.

Given the disruptions, this rule has been temporarily relaxed for IndiGo until February 10.

3. Reduced Maximum Night Flight Duty

Flight duty that stretches into the night is now capped at 10 hours.

This measure has also been kept on hold for IndiGo until February 10 to stabilize operations.

4. Weekly Rest Cannot Be Replaced With Personal Leave

Airlines can no longer count a pilot’s personal leave as part of the mandatory 48-hour rest.

Pilots say this closes a loophole that previously reduced actual rest time.

Currently, all airlines are exempt from this rule to normalise travel.

5. Mandatory Fatigue Monitoring

Airlines must submit quarterly fatigue reports along with corrective actions to DGCA.

This system aims to create a transparent fatigue-tracking framework across the industry.

The DGCA has stressed that these rules were crafted to strengthen flight safety and align India with global fatigue-management standards. The temporary relaxations are expected to remain until February 2025, giving IndiGo time to stabilise its schedules and restore normal air travel.
