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.

Thiruvananthapuram, Jan 19: The CPI(M) will soon launch a nation-wide house-to-house campaign to explain to the people, the 'link' between CAA-NPR-NRC, party general secretary, Sitaram Yechury said on Sunday.

The intense campaign will take place all over the country, he said while briefing the media about the three-day central committee held at Vilapilsala near here.

The central committee also urged the people not to answer the NPR questions.

"The Central committee has called upon the people not to answer any questions concerning the NPR when the enumerators come to their houses...," the left leader said.

Lucknow, Feb 2: In an early morning firing at Lucknow's Hazratganj, the city centre, Vishva Hindu Mahasabha state president Ranjit Bachchan was killed while he was out on a morning walk on Sunday.

Ranjit Bachchan was taking a stroll in Hazratganj in the morning when bike-borne assailants opened fire on him and killed him on the spot. The Mahasabha leader was shot in the head multiple times.

The incident took place near the CDRI building in Lucknow's Hazratganj.

In the firing, Ranjit Bachchan's brother also suffered bullet injuries. He has been rushed to the trauma centre. Ranjit Bachchan was a resident of Gorakhpur.

The early morning shootout in the Uttar Pradesh capital's central area has caused tension in the area.

Dinesh Singh, DCP Central Lucknow, said, "The body has been identified as of Ranjit Bachchan, who had gone out on morning walk when some unknown assailant shot him. A police team has been formed and further investigation is being carried out."

Before being associated with the Mahasabha, Ranjit Bachchan was a Samajwadi Party member and was often spotted with former UP chief minister Akhilesh Yadav.

The Samajwadi Party has hit out at the Yogi Adityanath government over the law and order situation in the state and demanded immediate resignation of the government.
