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.

May 28: Abdul Kareem was forced out of school and into a life of odd jobs like repairing bicycles before he finally managed to pull his family out of abject poverty transporting goods across Delhi in a mini truck.

The job, and the slim financial security that came with it, was the first stepping stone to a better life.

All that is now gone as India reels under the economic impact of its protracted coronavirus lockdown. Mr Kareem's out of a job and stranded in his village in Uttar Pradesh with his wife and two children. Their minuscule savings from his Rs 9,000 a month job have been exhausted, and the money he saved for books and school uniforms is spent.

"I don't know what the job situation will be in Delhi once we go back," Mr Kareem said. "We can't stay hungry so I will do whatever I find."

At least 49 million people across the world are expected to plunge into "extreme poverty" -- those living on less than $1.90 per day -- as a direct result of the pandemic's economic destruction and India leads that projection, with the World Bank estimating some 12 million of its citizens will be pushed to the very margins this year.

Some 122 million Indians were forced out of jobs last month alone, according to estimates from the Center for Monitoring Indian Economy, a private sector think tank. Daily wage workers and those employed by small businesses have taken the worst hit. These include hawkers, roadside vendors, workers employed in the construction industry and many who eke out a living by pushing handcarts and rickshaws.

For Prime Minister Narendra Modi, who came to power in 2014 promising to lift the poorest citizens out of poverty, the fallout from the lockdown brings with it significant political risk. He won an even larger second term majority last year on the strength of his government's popular social programs that directly targeted the poor, such as the provision of cooking gas cylinders, power and public housing. The breadth and depth of this renewed economic pain will only increase the pressure on his government as it works to steer the country's economy back on track.

"Much of the Indian government's efforts to mitigate poverty over the years could be negated in a matter of just a few months," said Ashwajit Singh, managing director of IPE Global, a development sector consultancy that advises several multinational aid agencies. Noting that he did not expect unemployment rates to improve this year, Singh said: "More people could die from hunger than the virus."

Desperate Times

Mr Singh points to a United Nations University study estimating 104 million Indians could fall below the World Bank-determined poverty line of $3.2 a day for lower-middle-income countries. This will take the proportion of people living in poverty from 60% -- or 812 million currently, to 68% or 920 million -- a situation last seen in the country more than a decade ago, he said.

A World Bank report found the country had been making significant progress and was close to losing its status as the country with the most poor citizens. The impact of PM Modi's lockdown risks reversing those gains.

The World Bank and the CMIE estimates were published in late April and early May respectively. Since then the situation has only become grimmer, with harrowing images of people making desperate attempts to reach their villages, on crowded buses, the flatbeds of trucks and even on foot or on bicycles dominating media coverage.

The Rustandy Center for Social Sector Innovation at the University of Chicago Booth School of Business analyzed the unemployment data from the CMIE, collected through surveys covering about 5,800 homes across 27 states in April.

Researchers found rural areas were the hardest hit, and the economic misery was the result of the lockdown, rather than the spread of infections in the hinterland. More than 80% of households had experienced a drop income and many won't survive much longer without aid, they wrote in a report.

The government has promised cheap credit to farmers, direct transfer of money to the poor and eased access to food security programs -- but these help people who have some documentation, which many of the poorest don't. With millions of impoverished people now in transit across the country, the food security situation is dire -- news reports are emerging of people foraging through piles of rotting fruit or eating leaves.

Shattered Economy

The economy was already growing at its slowest pace in over a decade when the virus struck. The lockdown, which came into effect on March 25, has hammered it, stalling business activity and putting a lid on consumption, pushing the economy to what may be its first full-year contraction in more than four decades.

It's dire enough to warrant the country exiting its lockdown, as it has been doing incrementally since May 4, even as its infections are surging. India is now Asia's virus hotspot with infections crossing 151,000 according to data from Johns Hopkins University.

PM Modi, who has come under criticism for the pain inflicted on the poor, has said his government will spend $265 billion or about 10% of its GDP to help Asia's third-largest economy weather the pandemic's fallout. But experts say only a part of it is direct fiscal stimulus, and probably smaller than the total damage done to the economy during the lockdown period.

"What is especially worrying is the government's response," said Reetika Khera, an economics professor at the Indian Institute of Technology in Delhi. "The epidemic will magnify existing -- and already high -- inequalities in India."

Still, the economic measures aren't going to kick in for some time and industry will likely struggle to restart because of the flight of labour from industrial hubs.

And as the harsh summer unfolds more pain lies in store in the villages now dealing with returning migrant workers.

"There are no factories or industries here, there are just hills," said Surendra Hadia Damor, who had walked nearly 100 km from Ahmedabad, Gujarat, before a voluntary organisation drove him to his village in the neighboring state of Rajasthan. "We can survive for a month or two and then try and find a job nearby -- we will see what happens."

New Delhi, Jan 7: The Delhi Police has filed an FIR against JNUSU president Aishe Ghosh and 19 others for allegedly attacking security guards and vandalising the server room of the Jawaharlal Nehru University (JNU) on January 4.

The police registered the FIR on January 5.

In the complaint filed by the JNU administration, the University alleged that the accused were involved in physical violence and pushed the women guards, verbally abused them and threatened them of dire consequences if they opened the lock of university's communication and information (CIS) office.

"They illegally trespassed the University property with the criminal intention to damage the public property. They damaged servers and made it dysfunctional. They also damaged fiber optic power supplies and broke the biometric systems inside the room," the University officials alleged.

This incident allegedly occurred a day before Aishe Ghosh, other JNU students and teachers were attacked by a masked mob inside the campus.
