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, Jun 13: Petrol price on Saturday was hiked by 59 paise per litre and diesel by 58 paise as oil companies for the seventh day in a row adjusted retail rates in line with costs since ending an 82-day hiatus in rate revision.

Petrol price in Delhi was hiked to Rs 75.16 per litre from Rs 74.57, while diesel rates were increased to Rs 73.39 a litre from Rs 72.81, according to a price notification of state oil marketing companies.

Rates have been increased across the country and vary from state to state depending on the incidence of local sales tax or VAT.

This is the seventh daily increase in rates in a row since oil companies on Sunday restarted revising prices in line with costs, after ending an 82-day hiatus.

In seven hikes, petrol price has gone up by Rs 3.9 per litre and diesel by Rs 4.

The freeze in rates was imposed in mid-March soon after the government hiked excise duty on petrol and diesel to shore up additional finances.

Oil PSUs Indian Oil Corp (IOC), Bharat Petroleum Corp Ltd (BPCL) and Hindustan Petroleum Corp Ltd (HPCL), instead of passing on the excise duty hikes to customers, adjusted them against the fall in the retail rates that was warranted because of a decline in international oil prices.

Ahmedabad, Feb 24: US President Donald Trump and his wife Melania on Monday tried their hands at spinning the 'charkha' (spinning wheel) at the Sabarmati Ashram here.

Accompanied by PM Narendra Modi, the US president and his wife went around the Ashram, before resuming the roadshow from the airport to the Motera stadium. "To my great friend Prime Minister Naredra Modi, thank you for this wonderful visit," Trump wrote in the Ashram visitors' book.

The US President was briefed about Gandhiji and the importance of charkha as a symbol of self reliance. Trump reached Ahmedabad at 11.37 am for the first leg of his India visit.

US President Donald Trump arrived in Ahmedabad on Monday for the first leg of his India trip. The Air Force One plane carrying Trump and his wife Melania landed at the Sardar Vallabhbhai Patel international airport here at 11.37 am, officials said. It was scheduled to land at 11.40 am.

Trump, who is also accompanied by daughter Ivanka, son-in-law Jared Kushner and top brass of his administration, will get a taste of India's cultural melange during his high- optics Gujarat itinerary, after the bonhomie between the two leaders at the 'Howdy, Modi!' event in Houston last year.
