I am confident that BJP will win: Shivraj Singh Chouhan

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.

Lucknow, May 25: Migrant workers who wish to return to their places of work after the lockdown is lifted, may no longer find the going easy now.

Uttar Pradesh Chief Minister Yogi Adityanath has said that his government will lay down stringent conditions for ensuring social security of workers from the state who are hired by other states.

"Other states will also need to seek permission from his government before engaging workers from UP," he said while addressing a webinar on Sunday.

The Chief Minister stated, "If any state wants manpower, the state government will have to guarantee social security and insurance of the workers. Without our permission they will not be able to take our people," he said.

He said all migrant workers who have returned to the state were being registered and their skills were being mapped by the administration. Any state or entity interested in hiring them will need to take care of their social, legal and monetary rights.

Speaking about the challenges his administration had faced during this crisis, the Chief Minister said, "When I talk of Uttar Pradesh, then it is natural to say that it is the state with the highest population. We have faced several challenges during the lockdown. At the beginning, migrant workers and labourers started coming to the state. We deployed 16,000 buses and within 24 hours, they were brought back to their home districts and arrangements were made to screen them."

Yogi Adityanath took a dig at the opposition leaders for the migrant crisis. "During the lockdown, if those who now raise slogans for the poor had honestly cared about workers, then migration could have been stopped. This did not happen. No facilities were given. At several places, electricity connections were cut, so people had to migrate." he said.

Legal experts, meanwhile said that requiring government permission for employing people could face a legal challenge as the Constitution guarantees the freedom of movement and residence and employment of workers.

"Article 19 (1)(D) guarantees freedom to move freely, and 19(1)(e) the freedom to settled in any part of the countryso the need for permission can be legally challenged," said a senior lawyer.

Perambalur, Jan 2: Veteran Tamil writer Nellai Kannan was arrested in Perambalur for criticizing Prime Minister Narendra Modi and Home Minister Amit Shah during a protest against Citizenship (Amendment) Act.

The Tirunelveli Police had registered the FIR against the writer for the speech delivered at a meeting, which was called by the Social Democratic Party of India on December 29 last year.

The police have booked him on the basis of multiple complaints filed by BJP leaders.

Kannan has been booked under Sections 504, 505(1) and 505(2) of the Indian Penal Code.
