Pranab Mukherjee too valuable for Congress to be made President?

New Delhi, Fevb 10: Of the countries most at risk of importing coronavirus cases, India ranks 17th, researchers have found on the basis of a mathematical model for the expected global spread of the virus that originated in China's Wuhan area in December 2019.

So far, India has reported three coronavirus positive cases -- all from Kerala.

Among the airports in India, the Indira Gandhi International Airport in New Delhi is most at risk, followed by airports in Mumbai, Kolkata, Bengaluru, Chennai, Hyderabad and Kochi, according to the model.

The new model for predicting global novel coronavirus cases has been developed by researchers from Humboldt University and Robert Koch Institute in Germany.

"The spread of the virus on an international scale is dominated by air travel," said the study.

"Wuhan, the seventh largest city in China with 11 million residents, was the relevant major domestic air transportation hub with many connecting international flights before the city was effectively quarantined on January 23, 2020, and the Wuhan airport was closed. By then the virus had already spread to other Chinese provinces as well as other countries," it added.

The researchers said that it is possible to estimate how likely it is that the virus spreads to other areas by looking at air travel passenger numbers.

"The busier a flight route, the more probable it is that an infected passenger travels this route. Using these probabilistic concepts, we calculate the relative import risk to other airports. When calculating the import risk, we also take into account connecting flights and travel routes that involve multiple destinations," said the study.

The top 10 countries and regions at risk of importing coronavirus cases are: Thailand, Japan, South Korea, Hong Kong, Taiwan, USA, Vietnam, Malaysia, Singapore and Cambodia, according to the model.

While Thailand's national import risk is 2.1%, it is 0.2% for India, found the research.

The foundation of the model is the worldwide air transportation network (WAN) that connects approximately 4,000 airports with more than 25,000 direct connections.

The model accounts for both, the current distribution of confirmed cases in mainland China as well as airport closures that were implemented as a mitigation strategy.

This network theoretic model is based on the concept of effective distance and is an extension of a model introduced in the 2013 paper "The Hidden Geometry of Complex, Network-Driven Contagion Phenomena" published in the journal Science.

The current outbreak of the 2019-nCoV virus started in Wuhan city, Hubei province, China. While the first cases were reported as early as December 8, 2019, the outbreak gained global attention on December 31, 2019, when the World Health Organization was alerted to "several cases of pneumonia" by an unknown virus.

The new virus was soon identified as a novel coronavirus and named 2019-nCOV. It belongs to the family of viruses that include the common cold and viruses such as SARS and MERS. On January 20, 2020, it was confirmed that the coronavirus can be transmitted between humans, greatly increasing the risk of a global spread.

The death toll due to the novel coronavirus outbreak in China has increased to 811 on Sunday, surpassing that of the Severe Acute Respiratory Syndrome (SARS) epidemic in 2003.

Although about 20 countries have confirmed cases, China has accounted for about 99 per cent of those infected. The first foreign victims of the virus both died on Saturday in Wuhan.

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."

Jaipur, Mar 29: A batch of 275 Indians evacuated from coronavirus-hit Iran arrived at the Jodhpur airport on Sunday morning, an official said.

He said a preliminary screening of the passengers was conducted at the airport and thereafter, they were shifted to the Army Wellness Facility set up at the Jodhpur Military Station.

Additional Chief Secretary (Health) Rohit Kumar Singh said of the 275 passengers, there were 133 women and 142 men, including two infants and four children.
