Amit Shah arrives in Kerala to attend 90th Mahasamadhi of Sree Narayana Guru

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.

Tehran, Mar 3: Iranian Foreign Minister Javad Zarif on Monday urged Indian authorities to ensure the well-being of all Indians and not let "senseless" violence prevail.

Ministry of External Affairs Spokesperson Raveesh Kumar said on Thursday that law enforcement agencies were working on the ground to prevent violence and ensure restoration of confidence and normalcy.

Mr Kumar has urged international bodies not to make irresponsible statements at this sensitive time. "Iran condemns the wave of organised violence against Indian Muslims. For centuries, Iran has been a friend of India. We urge Indian authorities to ensure the wellbeing of ALL Indians & not let senseless thuggery prevail. Path forward lies in peaceful dialogue and rule of law," Zarif tweeted.

The communal violence over the amended citizenship law in Delhi has claimed at least 42 lives. Frenzied mobs have torched houses, shops, vehicles, a petrol pump and pelted stones at police personnel.

Kathmandu, June 18: Nepal's National Assembly on Thursday unanimously passed the Constitution Amendment Bill to update the country's political and administrative map incorporating three Indian territories. 

The new map also includes land controlled by India. It requires President Bidhya Devi Bhandari's approval.

India, which controls the region - a slice of land including Limpiyadhura, Lipulekh and Kalapani areas in the northwest - has rejected the map, saying it is not based on historical facts or evidence.

India has termed as untenable the "artificial enlargement" of territorial claims by Nepal after its lower house of parliament on Saturday unanimously approved the new political map of the country featuring areas which India maintains belong to it.

The National Assembly, or the upper house of the Nepalese parliament, unanimously passed the constitution amendment bill providing for inclusion of the country's new political map in its national emblem.

The bill was passed with all the 57 members present voting in its favour.

The dispute

The latest border dispute between the countries began last month after India inaugurated Himalayan link road built in a disputed region that lies at a strategic three-way junction with Tibet and China.

The 80km (50-mile) road, inaugurated by Indian Defence Minister Rajnath Singh, cuts through the Lipulekh Himalayan pass, considered one of the shortest and most feasible trade routes between India and China.

The road cuts the travel time and distance from India to Tibet's Mansarovar lake, considered holy by the Hindus.

But Nepal says about 19km of the road passes through its area and fiercely contested the inauguration of the road, viewing the alleged incursion as a stark example of bullying by its much larger neighbour.

Nepal, which was never under colonial rule, has long claimed the areas of Limpiyadhura, Kalapani and Lipulekh under the 1816 Sugauli treaty with the British East India Company, although these areas have remained under the control of Indian troops since India fought a war with China in 1962.
