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, Feb 29: With Saudi Arabia indefinitely suspending visas for visit to Islam's holiest site for the Umrah pilgrimage in the wake of coronavirus outbreak, more than 10,000 people in the state who are awaiting their turn this year for the annual Hajj pilgrimage are a worried lot.

"This year more than 10,000 people in Kerala have been cleared by the Hajj committee," said C Muhammed Faizy, chairman, Kerala State Hajj Committee.

"There is no cause of worry. We hope that during the time of the pilgrimage, the travel restriction by Saudi Arabia will be lifted," he said.

Umrah is a pilgrimage to the holy site that can be undertaken at any time of the year, while the annual Hajj pilgrimage has specific months according to the lunar calendar.

"The move by the Saudi Arabian Government to impose travel restriction was due to the outbreak of coronavirus. It is a preventive step to contain it. In such large gatherings, if one person is affected, it will spread to others. So we fully understand the concerns of the Saudi Government," Muhammed Faizy added.

He said that the Hajj Committee only processes the requests of annual Hajj visit pilgrims and not Umrah.

"This year we expect the Hajj pilgrimage season to be from June to August after Ramzan. But it may vary according to the Ramzan date. We are yet to get any official correspondence from the Saudi Government regarding travel restrictions," he added.

The Saudi Arabian Government suspended visas for tourists from countries affected by the coronavirus, with many having to cancel their Umrah pilgrimage at the last minute.

Lucknow, Jul 19: The animal markets, which are usually bustling with activity ahead of Bakrid, are desolate this year.

The Covid-19 pandemic has shorn all festivals of public celebrations, and people are apprehensive that the tradition of animal sacrifice may be affected due to social distancing norms.

Also there is a massive drop in demand for sacrificial animals due to the financial impact of the crisis.

Chairman of All India Jamiat-ul-Quresh Sirajuddin Qureshi urged the government to come out with guidelines for carrying out the celebrations in the traditional way.

The festival will fall on July 31 or August 1. Buyers and sellers start thronging the animal markets almost two weeks ahead of the festival. But this year only a negligible number of buyers have turned up in animal markets in old Lucknow areas including Nakkhas, according to traders.

"It is very difficult to say as to what the government is thinking. 'Qurbani' is a matter of faith for the Muslims. We appeal to the government to deliberate and find a solution. This is a national problem, and our office bearers are speaking to different state governments," Qureshi said.

In the absence of guidelines, not many madrassas are buying animals for sacrifice, he said.

"The madrasas where collective 'qurbani' is done, are also not coming forward. In Bakrid, along with goats, buffaloes are also sacrificed. The government should ensure that people who are transporting the animals are not harassed by the police," Qureshi said.

Prominent Muslim cleric Khalid Rasheed Farang Mahali said he had raised the issue with the Uttar Pradesh chief minister.

"I have recently met Chief Minister Yogi Adityanath requesting him to issue guidelines for Bakrid. I am hopeful that the guidelines will be released soon," he said.

Rahat Ali, a goat trader from Rajasthan said, thousands of people will be affected due to the reduced demand for animals.

"The animal trade works in a chain involving farmers who rear animals, small traders and big traders.

"The traders buy the animals from the farmers. These are then sent to various states like Maharashtra, Gujarat and Uttar Pradesh. In the absence of demand, I did not purchase animals this year," he said.

Sajid, who supplies goats to various districts in western Uttar Pradesh, said the lockdown has affected the livelihood of people and not many have the money to buy animals for sacrifice.

"The lockdown has drained the people of their money. As a result, the animals are not getting sold," he said.

The Maharashtra government has come out with guidelines for Eid al-Adha, also known as Bakrid or Id-ul-Zuha, noting that there is a ban in place on all religious programmes and people should offer "namaz" in their homes and not in mosques.

It also said sacrificial animals should be bought online or over the phone as markets dealing with them will be closed, adding that "qurbani" should preferably be symbolic.

There will be no relaxation in restrictions for Eid in containment zones, and people are directed not to congregate in public places on the day of the festival, it added.
