We keep ourselves away from politics, we follow govt directives: CDS Gen Bipin Rawat

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, Jan 16: The drive initiated by Uttar Pradesh's Yogi Adityanath government to identify non-Muslim immigrants in the state seems to have run into rough weather.

In Pilibhit, where the maximum number of about 35,000 illegal immigrants has been identified, it has now been found that information is being sought by the state government on an unverified document. A large number of families from Bangladesh settled here several decades ago.

The survey began last month even before the bill was notified. Moreover, the feedback email on the questionnaire is a Gmail ID -- [email protected] -- which is not a government server.

It is not known how the state government is drawing up the lists without having the verification criteria.

After the report was put up by a news website, Home Department officials feigned complete ignorance about the issue.

A spokesman said: "This was an unofficial and preliminary exercise to assess the number of illegal migrants in the state. The document is meant to collect basic beneficiary information. No list of potential beneficiaries has yet been sent to Delhi."

The document has eight columns asking for name, father's name, place of stay in India, and where did they come from and when. It does not mention any requirement of proof, or documents.

It also asks for a description of the kind of atrocities they faced, presumably in their home country.

The District Magistrate of Pilibhit claimed they are checking documents of the refugees, but denied any knowledge of the unsigned document.

The CAA is meant to benefit Hindus, Sikhs, Buddhists, Jains, Parsis and Christians from Pakistan, Bangladesh and Afghanistan who came to India before December 31, 2014. The statement of purposes of the Act adds that it is meant to benefit those fleeing religious persecution from the above countries.
