Haj pilgrims from India start flying to Saudi Arabia

New Delhi, May 18: With the highest-ever spike of 5,242 new cases in last 24 hours, the total number of positive COVID-19 cases in India reached 96,169 on Monday, according to the Ministry of Health and Family Welfare.

With 157 deaths reported in the last 24 hours, the death toll has risen to 3,029, as per the latest update by the ministry.

Out of the total number of cases, 36,824 have been cured/discharged/migrated.

This comes a day after the nationwide lockdown, imposed as a precautionary measure to contain the spread of COVID-19, was extended till May 31.

Maharashtra remains the worst-affected state due to the virus with 33,053 cases, including 1,198 deaths. It is followed by Gujarat (11,379), Tamil Nadu (11,224) and Delhi (10,054).

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

Munbai/New Delhi, May 4: India expects bad debts at its banks could double after the coronavirus crisis brought the economy to a sudden halt, a senior government official and four top bankers said.

Indian banks are already grappling with 9.35 trillion rupees ($123 billion) of soured loans, which was equivalent to about 9.1% of their total assets at the end of September 2019.

"There is a considered view in the government that bank non-performing assets (NPAs) could double to 18-20% by the end of the fiscal year, as 20-25% of outstanding loans face a risk of default," the official with direct knowledge of the matter said.

A fresh surge in bad debt could hit credit growth and delay India's recovery from the coronavirus pandemic.

"These are unprecedented times and the way it's going we can expect banks to report double the amount of NPAs from what we've seen in earlier quarters," the finance head of a top public sector bank told Reuters.

The official and bankers declined to be named as they were not officially authorized to discuss the matter with media.

India's finance ministry declined to comment, while the Reserve Bank of India and Indian Banks' Association, the main industry body, did not immediately respond to emails seeking comment.

The Indian economy has ground to a standstill amid a 40-day nationwide lockdown to rein in the spread of coronavirus cases.

The lockdown has now been extended by a further two weeks, but the government has begun to ease some restrictions in districts that are relatively unscathed by the virus.

India has so far recorded nearly 40,000 cases of the coronavirus and more than 1,300 deaths from COVID-19, the respiratory disease caused by the coronavirus.

'RIDING THE TIGER'

Bankers fear it is unlikely that the economy will fully open up before June or July, and loans, especially those to small- and medium-sized businesses which constitute nearly 20% of overall credit, may be among the worst affected.

This is because all 10 of India's largest cities fall in high-risk red zones, where restrictions will remain stringent.

A report by Axis Bank said that these red zones, which contribute significantly to India's economy, account for roughly 83% of the overall loans made by its banks as of December.

One of the sources, an executive director of a public sector bank, said that economic growth had been sluggish and risks had been heightened, even ahead of the coronavirus crisis.

"Now we have this Black Swan event which means without any meaningful government stimulus, the economy will be in tatters for several more quarters," he said.

McKinsey & Co last month forecast India's economy could contract by around 20% in the three months through June, if the lockdown was extended to mid-May, and growth in the fiscal year was likely to fall 2% to 3%.

Bankers say the only way to stem the steep rise in bad loans is if the RBI significantly relaxes bad asset recognition rules.

Banks have asked the central bank to allow all loans to be categorized as NPAs only after 180 days, which is double the current 90-day window.

"The lockdown is like riding the tiger, once we get off it we'll be in a difficult position," a senior private sector banker said.
