Melbourne, Oct 12: The virus that causes Covid-19 can survive on banknotes, glass and stainless steel for up to 28 days, much longer than the flu virus, Australian researchers said on Monday, highlighting the need for cleaning and handwashing to combat the virus.

Researchers at Australia's national science agency, CSIRO, found that at 20 degrees Celsius (68 degrees Fahrenheit) the SARS-COV-2 virus remained infectious for 28 days on smooth surfaces such as plastic banknotes and glass found on mobile phone screens. The study was published in Virology Journal.

By comparison, Influenza A virus has been found to survive on surfaces for 17 days.

CSIRO's research involved drying virus in an artificial mucus on a range of surfaces at concentrations similar to samples from Covid-19 patients and then extracting the virus after a month.

Experiments done in controlled laboratory environments at 20, 30 and 40 degrees C showed that the survival time declined as the temperature increased.

"Establishing how long the virus really remains viable on surfaces enables us to more accurately predict and mitigate its spread and do a better job of protecting our people," CSIRO Chief Executive Larry Marshall said in a statement.

Proteins and fats in body fluids can also sharply increase virus survival times.

"The research may also help to explain the apparent persistence and spread of SARS-CoV-2 in cool environments with high lipid or protein contamination, such as meat processing facilities, and how we might better address that risk," said Trevor Drew, director of the CSIRO’s Australian Centre for Disease Preparedness.

Australia has fared much better than most other rich nations in combating Covid-19, with a total of about 27,000 infections and 898 deaths in a population of 25 million.

The epicentre of the country's second wave of infection, Victoria state, reported 15 new cases on Monday, well shy of a target of less than five which the government has set for the easing of a hard lockdown in the state capital Melbourne.

New South Wales, the most populous state, reported six new cases on Monday, five of whom were returned travelers in quarantine.

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.

Congress president Mallikarjun Kharge on Thursday announced that he will convene a high-level meeting in New Delhi with senior leaders — including Rahul Gandhi, Karnataka Chief Minister Siddaramaiah and Deputy Chief Minister D.K. Shivakumar — to resolve the escalating leadership turmoil in Karnataka and “put an end to the confusion.”

Kharge said the discussions would focus on the way forward for the ruling party, as rumours of a possible leadership change continue to swirl. The speculation has intensified after the Congress government crossed the halfway mark of its five-year term on November 20, reviving talk of an alleged 2023 “power-sharing agreement” between Siddaramaiah and Shivakumar.

“After reaching Delhi, I will call three or four important leaders and hold discussions. Once we talk, we will decide how to move ahead and end this confusion,” Kharge told reporters in Bengaluru, according to PTI.

When asked specifically about calling Siddaramaiah and Shivakumar to Delhi, he responded: “Certainly, we should call them. We will discuss with them and settle the issue.”

He confirmed that Rahul Gandhi, the Chief Minister, the Deputy Chief Minister and other senior members would be part of the deliberations. “After discussing with everyone, a decision will be made,” he said.

Meanwhile, Siddaramaiah held a separate strategy meeting at his Bengaluru residence with ministers and leaders seen as his close confidants, including G. Parameshwara, Satish Jarkiholi, H.C. Mahadevappa, K. Venkatesh and K.N. Rajanna.
Signalling calm, the Chief Minister told reporters, “Will go to Delhi if the high command calls.”

Shivakumar echoed a similar stance, saying he too would head to the national capital if summoned by the party leadership.

Domestic carrier IndiGo has cancelled over 180 flights from three major airports — Mumbai, Delhi and Bengaluru — on Thursday, December 4, as the airline struggles to secure the required crew to operate its flights in the wake of new flight-duty and rest-period norms for pilots.

While the number of cancellations at Mumbai airport stands at 86 (41 arrivals and 45 departures) for the day, at Bengaluru, 73 flights have been cancelled, including 41 arrivals, according to a PTI report that quoted sources.

"IndiGo cancelled over 180 flights on Thursday at three airports-Mumbai, Delhi and Bengaluru," the source told the news agency.

Besides, it had cancelled as many as 33 flights at Delhi airport for Thursday, the source said, adding, "The number of cancellations is expected to be higher by the end of the day."

The Gurugram-based airline's On-Time Performance (OTP) nosedived to 19.7 per cent at six key airports — Delhi, Mumbai, Chennai, Kolkata, Bengaluru and Hyderabad — on December 3, as it struggled to get the required crew to operate its services, down from almost half of December 2, when it was 35 per cent.

"IndiGo has been facing acute crew shortage since the implementation of the second phase of the FDTL (Flight Duty Time Limitations) norms, leading to cancellations and huge delays in its operations across the airports," a source had told PTI on Wednesday.

Chaos continued at several major airports for the third day on Thursday because of the cancellations.

A spokesperson for the Kempegowda International Airport (KIA) in Bengaluru said that 73 IndiGo flights had been cancelled on Thursday.

At least 150 flights were cancelled and dozens of others delayed on Wednesday, airport sources said, leaving thousands of travellers stranded, according to news agency Reuters.

The Directorate General of Civil Aviation (DGCA) has said it is investigating IndiGo flight disruptions and has asked the airline to submit the reasons for the current situation, as well as its plans to reduce flight cancellations and delays.

It may be mentioned here that the pilots' body, Federation of Indian Pilots (FIP), has alleged that IndiGo, despite getting a two-year preparatory window before the full implementation of new flight duty and rest period norms for cockpit crew, "inexplicably" adopted a "hiring freeze".

The FIP said it has urged the safety regulator, the DGCA, not to approve airlines' seasonal flight schedules unless they have adequate staff to operate their services "safely and reliably" in accordance with the New Flight Duty Time Limitations (FDTL) norms.

In a letter to the DGCA late on Wednesday, the FIP urged the DGCA to consider re-evaluating and reallocating slots to other airlines, which have the capacity to operate them without disruption during the peak holiday and fog season if IndiGo continues to "fail in delivering on its commitments to passengers due to its own avoidable staffing shortages."
