PM attacks Cong, then reaches out to Oppn for support

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.

From March through May, around 1 crore migrant workers fled India’s megacities, afraid to be unemployed, hungry and far from family during the world’s biggest anti-Covid-19 lockdown.

Now, as Asia’s third-largest economy slowly reopens, the effects of that massive relocation are rippling across the country. Urban industries don’t have enough workers to get back to capacity, and rural states worry that without the flow of remittances from the city, already poor families will be even worse off -- and a bigger strain on state coffers.

Meanwhile, migrant workers aren’t expected to return to the cities as long as the virus is spreading and work is uncertain. States are rolling out stimulus programs, but India’s economy is hurtling for its first contraction in more than 40 years, and without enough jobs, a volatile political climate gets more so.

“This will be a huge economic shock, especially for households of short-term, cyclical migrants, who tend to come from vulnerable, poor and low-caste and tribal backgrounds,” said Varun Aggarwal, a founder of India Migration Now, a research and advocacy group based in Mumbai.

In the first 15 days of India’s lockdown, domestic remittances dropped by 90%, according to Rishi Gupta, chief executive officer of Mumbai-based Fino Paytech Ltd., which operates the country’s biggest payments bank.

By the end of May, remittances were back to around 1750 rupees ($23), about half the pre-Covid average. Gupta’s not sure how soon it’ll fully recover. “Migrants are in no hurry to come back,” Gupta said. “They’re saying that they’re not thinking of going back at all.”

If workers stay in their home states long term, policymakers will have more than remittances to worry about. If consumption falls and the new surplus of labor drives wages down, Agarwal said, “there will also be a second-order shock to the local economy. Overall, not looking good.”

India announced a $277 billion stimulus package in May and followed it up with a $7 billion program aimed at creating jobs for 125 days for migrants in villages across 116 districts. Separately, local authorities are also looking for solutions.

Officials in Bihar have identified 2,500 acres of land that could be made available to investors, said Sushil Modi, deputy chief minister of Bihar, a state in east India. “We can use this crisis as an opportunity to speed up reforms,” he said.

The investors haven’t materialised yet, and in the meanwhile, state governments are relying on the national cash-for-work program that guarantees 100 days worth of wages per household.

Skilled workers don’t want to do manual labor offered through the program, and even if they did, says Amitabh Kundu of RIS, many think of it as beneath their station. “There will be an increase in social tensions,” he predicts. “Caste may again start playing a role. It’s absolute chaos.”

For skilled workers, initiatives vary:

* Uttar Pradesh, which received 3.2 million people, is compiling lists of skilled workers who need employment and trying to place them with local manufacturing and real estate industry associations. So far, the government says, it’s placed 300,000 people with construction and real estate firms.

* Bihar has placed returners in state-run infrastructure projects and hired others to stitch uniforms and make furniture for government-run schools, even as they waited in quarantine centres, said Pratyay Amrit, head of the state’s disaster management department.

* The eastern state of Odisha announced an urban wage employment program aimed at putting as many as 450,000 day labourers to work through September. Some 25,000 people have been employed, so far, under the scheme, G. Mathivathanan, principal secretary for housing and urban development said.

Attracting Investments

It’s not clear any of this will be enough to make a dent, says Ravi Srivastava, professor at New Delhi-based Institute of Human Development, adding that the states don’t have much of a track record on economic development.

“It was the failure of these states to improve governance and put development plans in place that led to the out-migration in the first place,” he said.

But officials and workers’ rights advocates see opportunity. Uttar Pradesh has established liaisons to encourage companies from the US, Japan and South Korea to establish manufacturing in the state. There and in Madhya Pradesh and Rajasthan, the government has made labour laws more friendly to employers, making it easier to hire and fire workers.

Modi, the minister from Bihar, said the migration may also give workers--historically a disenfranchised group--new power, particularly as urban centres struggle. “The way industries treated workers during the lockdown -- didn’t pay them, the living conditions were poor -- now these industries will realize the value of this force,” Modi said.

“In the days to come, labour will emerge as a force that can’t be ignored anymore,” he added. “That’s the new normal. We will work out how to ensure dignity, rights to our people who are going to work in other states.”

Bihar is due for elections by November, a vote that could be an early test of the mass migration’s political consequences. The state is currently governed by a coalition that includes Prime Minister Narendra Modi’s Bharatiya Janata Party. Amitabh Kundu, a fellow at the Research and Information System for Developing Countries, a New Delhi-based government think-tank, said migrant workers are likely to be angry voters.

“Chief ministers are telling these migrants that they will not have to go back for work,” he said. “But their capacity to do something miraculous in the next four to five months is doubtful. If they can retain even one-fourth of the migrants, I would call it a success.”
