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.

Leh, Jul 3: Taking an apparent dig at China, Prime Minister Narendra Modi on Friday said the age of expansionism is over and added that the new age of development is here.

"Age of expansionism is over, this is the age of development. History is witness that expansionist forces have either lost or were forced to turn back," Modi said addressing soldiers in Ladakh's Nimmoo. However, the Prime Minister did not mention China at all in his address to the soldiers.

The remark comes amidst the ongoing tension between India and China at Line of Actual Control in the eastern Ladakh. In a violent face-off 20 Indian soldiers were killed in the Galwan Valley on June 15-16 when Chinese troops attempted to unilaterally change the status quo during the de-escalation.

The Prime Minister also said that the people of Ladakh have rejected every attempt to create separatism in the region.

"Ladakh is the head of the country. This is the symbol of pride for the 130 crore citizens of India. This land belongs to the people who are willing to make the ultimate sacrifice for the country... Every attempt to create separatism in the region was rejected by the nationalist people of Ladakh," Modi said.

He also said: "We are the same people who pray to the flute playing Lord Krishna, but we are also the same people who idealise and following the same Lord Krishna who carries the Sudarshan Chakra."

The two countries -- India and China -- have been involved in talks to ease the ongoing border tensions since last month.

Lauding the bravery displayed by the soldiers, the Prime Minister said: "The bravery that you and your compatriots showed, a message has gone to the world about India's strength."

"Your courage is higher than the heights where you are posted today," he added.

"Atmanirbhar Bharat ka sankalp aapke tyag, balidan, pursharth ke karan aur bhi mazbut hai,"(The determination of self-reliant India gets strengthened from your sacrifice and courage)," the Prime Minister said.

The soldiers were observed maintaining social distancing while PM Modi's address here.

PM Modi on Friday made a surprise visit to Ladakh and was briefed by senior officers at Nimmoo amid ongoing tension with China. The Prime Minister was accompanied by Chief of Defence Staff (CDS) General Bipin Rawat and Army Chief General Manoj Mukund Naravane.

He reached Nimmoo, early morning today and interacted with Army, Air Force and ITBP personnel.

Located at 11,000 feet, this is among the tough terrains, surrounded by Zanskar range and on the banks of the Indus.

Sources had earlier informed about CDS Rawat's visit to Leh today. General Rawat's visit holds importance since it comes in the wake of Defence Minister Rajnath Singh's visit to Ladakh being rescheduled.

Earlier, the Defence Minister was scheduled to visit Ladakh today to review the preparedness of the army amid the ongoing standoff with China.

The situation at the India-China border remains tense after 20 Indian soldiers lost their lives in a violent face-off in the Galwan valley on June 15-16 when Chinese troops attempted to unilaterally change the status quo during the de-escalation. India and China have been involved in talks to ease the ongoing border tensions since last month.

Jun 8: Petrol and diesel prices were hiked by 60 paisa per litre on Monday, for the second day in a row, as state-owned oil firms reverted to daily price revisions after a 83-day hiatus.

Petrol price in Delhi was hiked to Rs 72.46 per litre from Rs 71.86 on Sunday, while diesel rates were increased to Rs 70.59 a litre from Rs 69.99, according to a price notification of state oil marketing companies.

This is the second daily increase in rates in a row. Oil companies had on Sunday raised prices by 60 paisa per litre on both petrol and diesel after ending a 83-day hiatus in daily rate revision.

Daily price revision has restarted, an oil company official said.

While oil PSUs have regularly revised ATF and LPG prices, they had since March 16 kept petrol and diesel prices on hold, ostensibly on account of extreme volatility in the international oil markets.

Auto fuel prices were frozen soon after the government raised excise duty on petrol and diesel by Rs 3 per litre each to mop up gains arising from falling international rates.

The government on May 6 again raised excise duties by Rs 10 per litre on petrol and Rs 13 per litre on diesel.

Oil companies, instead of passing on the excise hike to consumers, decided to adjust them against the reduction required because of the drop in international oil prices. They used the same tool and did not pass on the Re 1 per litre hike required for switching over to ultra-clean BS-VI grade fuel from April 1.
