Modi renames 3 islands of Andaman and Nicobar

Apr 11: India has sent back 20,473 foreigners who wanted to return to their countries following the Covid-19 global pandemic, it was revealed on Friday (April 10).

"So far, we have successfully evacuated 20,473 foreign nationals as of yesterday. This is an ongoing process," said Dammu Ravi, Coordinator on Covid-19 issues at the Ministry of External Affairs, MEA.

"This involves several countries," Ravi said during the daily government briefing on Covid-19, although he could not list the countries offhand. "We are receiving excellent cooperation from governments all over the world for this process."

Many foreigners, especially tourists, were stranded in India when domestic and international flights were abruptly cancelled last month in a bid to curb transmission of the coronavirus.

The Ministry of Tourism has asked stranded foreigners to get in touch with the government through a special portal started for the purpose, through their embassies in India and other sources to facilitate their evacuation if they wished to head home.

As of Friday evening, the Ministry of Health and Family Welfare had confirmed 6,761 Covid-19 cases in India, of whom 515 patients have been cured.

There were 206 deaths reported from across the country.

Two states, Punjab and Orissa, have extended the ongoing lockdown until April 30.

Prime Minister Narendra Modi will consult state chief ministers on Saturday to decide whether to extend the country-wide lockdown, which is due to end at midnight on April 14.

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.
