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.

New Delhi, Feb 27: The death toll in the communal violence in northeast Delhi over the amended citizenship law reached 32 on Thursday, senior officials said.

It was at 27 till Wednesday night.

"Five more deaths recorded at GTB Hospital, so death toll at that hospital has gone up to 30, taking total toll to 32," a senior Delhi Health Department official told news agency.

The Lok Nayak Jai Prakash Narayan Hospital had reported two fatalities on Wednesday.

Bhopal, Mar 4: Madhya Pradesh Chief Minister  Kamal Nath on Tuesday asserted that there was no threat to his government.

Nath's comments came when he was asked about reports of alleged 'poaching' attempts being made by the opposition BJP in the state.

“The legislators are telling me that they are being offered so much money. I am telling the MLAs to take it, if they are getting this free money,” Nath told reporters here on the sidelines of a programme.

Congress veteran Digvijaya Singh on Monday alleged that his party MLAs were being offered “huge money by BJP leaders” as part of the saffron party's “poaching” attempt to destablise the Kamal Nath government.

When Nath was asked about any threat to the stability of his government in Madhya Pradesh, he said, “There is nothing to worry about.”

Reacting to Nath's statement, state BJP spokesman Rajneesh Agrawal told PTI that his party has nothing to do with the allegations.

“In fact, these speculations and allegations are part of the internal bickering of among Congress leaders to get nominated for the Rajya Sabha polls,” he said.

After Digvijaya Singh's remarks on Monday, senior BJP leader and former chief minister Shivraj Singh Chouhan accused the Congress veteran of making false statements to create sensationalism.

“Speaking lies to create sensationalism is Digvijaya's habit. Probably some of his (Digivijaya's) works were not done and he wants to create pressure on the CM to get them done,” Chouhan alleged.
