India land of scams, slums: Sri Sri Ravi Shankar

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.

As many as employees of Zee News have tested positive for the coronavirus, Editor-in-Chief Sudhir Chaudhary said on Monday. Most of them are asymptomatic, he said, tweeting an official statement from Zee News about the situation.

The organisation said that on May 15, one of its employees tested positive for the coronavirus. Following this, the company started testing employees who may have come in contact with the employee. Twenty-seven more were found to be infected.

“Fortunately most of them are asymptomatic and are not complaining of any discomfort,” Zee News said. “We believe this is because of early diagnosis and proactive intervention.”

The news network said all guidelines and protocols have been followed, and its office, newsroom and studios have been sealed for sanitisation. The Zee News team has been shifted to an alternative facility.

“At the moment, Zee Media Corporation has 2,500 employees, by far the largest in the private sector,” the company said. “We are committed to the safety of each one of them.”

Chaudhary also claimed that “those who are infected had the option of sitting at home and sharing memes”. “They came to work because they are committed professionals.”

Following this, some social media users claimed that Zee News employees found infected with Covid-19 were still at work. In response, Chaudhary alleged that a malicious campaign was being conducted to distort his statement. He said no infected employee had come to work, and all the contacts of the employee who tested positive on May 15 had been tested and quarantined.

Over the past two months, journalists from several media organisations have tested positive for the coronavirus. On April 21, 26 employees of a Tamil news channel based in Chennai tested positive for the coronavirus. The previous day, over 50 journalists from Mumbai were found infected, after samples of over 170 journalists were tested.

On May 7, a newspaper journalist died of the coronavirus in Agra. Some states, such as Uttar Pradesh, Karnataka and Delhi, have tested journalists for Covid-19.

Lucknow, Jan 6: Undeterred by the large scale protests that claimed as many as 20 lives in the state, Uttar Pradesh government has started the process of implementing the controversial Citizenship (Amendment) Act.

According to sources in the government, the district magistrates have been directed to identify the migrants from Pakistan, Bangladesh and Afghanistan, who have been living in their districts.

Sources said that the state home department has given oral instructions to the district magistrates. ''No written orders have been issued,'' said a senior official here preferring anonymity.

The official said that the district magistrates would be preparing a list containing names of those minorities, who had migrated from these countries following their persecution and had been living without obtaining the citizenship of India.

According to sources, the government expected that the migrants, who could be eligible for the Indian citizenship in accordance with the CAA, could be more in number in the districts, including Rampur, Ghaziabad, Shahjahanpur, Lucknow and some others.

''The list will be sent to the union home ministry,'' the official added.

Sources said that the state government will also inform the centre about the ''illegal Muslim migrants'' for their ultimate deportation to their countries of origin.

Different parts of UP had witnessed large scale violence last month during the protests against the CAA. At least 20 people, mostly youngsters, were killed allegedly in police firing and many others were injured. The state government had denied the charge. 

Alleged police excesses during and after the protests triggered a nationwide outrage with several rights organisations and activists slamming the BJP government and demanding a high-level probe into the allegations.
