‘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.

Udupi, Dec 1: A horrific case of alleged rape has unfolded in Udupi, where a worker from a Hindutva organisation, previously arrested and released on bail for harassing a young woman, is now accused of waylaying and sexually assaulting her.

The arrested individual has been identified as Pradeep Poojary (26), a member of the Hindu Jagarana Vedike's Nairkode unit in Perdur.

Poojary had allegedly been relentlessly harassing the young woman, pressuring her to marry him. When she bravely stood up to him and refused his demands, she filed a formal complaint at the Hiriyadka police station. He was subsequently arrested in that initial harassment case but was later granted bail.

According to police reports, driven by the same malicious grudge, Poojary allegedly intercepted the woman again on November 29. While she was walking through a deserted area, the accused is claimed to have threatened her by grabbing her neck. When she again refused to marry him, he allegedly proceeded to rape her.

The survivor immediately informed her family about the traumatic assault. Following this, her parents lodged a complaint at the Udupi women’s police station.

Police arrested Poojary again and produced him before the court. He has since been remanded to judicial custody.

New Delhi, Dec 5: IndiGo CEO Pieter Elbers issued a public apology this evening after more than a thousand flights were cancelled today, making it the "most severely impacted day" in terms of cancellations. The biggest airline of the country cancelled "more than half" of its daily number of flights on Friday, said Elbers. He also said that even though the crisis will persist on Saturday, the airline anticipates fewer than 1,000 flight cancellations.

"Full normalisation is expected between December 10 and 15, though IndiGo cautions that recovery will take time due to the scale of operations," the IndiGo CEO said. 

IndiGo operates around 2,300 domestic and international flights daily.

Pieter Elbers, while apologising for the major inconvenience due to delays and cancellations, said the situation is a result of various causes.

The crisis at IndiGo stems from new regulations that boost pilots' weekly rest requirements by 12 hours to 48 and allow only two night-time landings per week, down from six. IndiGo has attributed the mass cancellations to "misjudgment and planning gaps".

Elbers also listed three lines of action that the airline will adopt to address the issue.

"Firstly, customer communication and addressing your needs, for this, messages have been sent on social media. And just now, a more detailed communication with information, refunds, cancellations and other customer support measures was sent," he said.

The airline has also stepped up its call centre capacity.

"Secondly, due to yesterday's situation, we had customers stranded mostly at the nation's largest airports. Our focus was for all of them to be able to travel today itself, which will be achieved. For this, we also ask customers whose flights are cancelled not to come to the airports as notifications are sent," the CEO said.

"Thirdly, cancellations were made for today to align our crew and planes to be where they need to start tomorrow morning afresh. Earlier measures of the last few days, regrettable, have proven not to be enough, but we have decided today to reboot all our systems and schedules, resulting in the highest numbers of cancellations so far, but imperative for progressive improvements starting from tomorrow," he added.

As airports witnessed chaotic scenes, the Directorate General of Civil Aviation (DGCA) stepped in to grant IndiGo a temporary exemption from stricter night duty rules for pilots. It also allowed substitution of leaves with a weekly rest period. 

Civil Aviation Minister Ram Mohan Naidu has said a high-level inquiry will be ordered and accountability will be fixed.

Mangaluru, Dec 2: Mangaluru International Airport responded to a medical emergency late on Monday night. Air India Express flight IX 522, travelling from Riyadh to Thiruvananthapuram, was diverted to Mangaluru Airport after a passenger in his late 30s experienced a medical emergency on board.

The Airport’s Operations Control Centre received an alert regarding the passenger’s health condition. The airport activated its emergency response protocol, mobilising the airport medical team and coordinating with stakeholders including CISF, immigration, and customs. 

Upon landing, airport medical personnel attended to the passenger, assessed his condition, and arranged to shift him to a local tertiary-care hospital for further treatment. The passenger’s relatives accompanied the passenger, who incidentally received necessary medical care on board, which helped stabilise the situation.

Following the handling of the emergency, the flight departed for Thiruvananthapuram at 2:05 am on Tuesday.

"We appreciate the cooperation of all parties involved, and this incident reaffirms our ongoing commitment to prioritising passenger safety and readiness to respond to unforeseen emergencies with professionalism and care," the Airport spokesperson said.
