'If honest, Modi should not fear CBI probe in Rafale Deal, Says Arvind Kejriwal

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, Feb 11: Delhi BJP chief Manoj Tiwari on Tuesday said the party will review why it failed to meet its own expectations in the Assembly polls and saw a moral victory in the fact that the party's vote share has increased since 2015.

"Delhi must have given mandate after careful thinking. Our vote percentage has increased from 32 per cent to around 38 per cent. Delhi did not reject us and the increase (in vote share) is a good sign for us," he told reporters.

He said the BJP hopes that there would be less blame game and more work in the national capital and congratulated Arvind Kejriwal on his party's victory in the polls.

After winning the Patparganj seat, AAP senior leader Manish Sisodia accused the BJP of indulging in the politics of hate.

"We indulge in politics of development not politics of hate. We're against the roadblock in Shaheen Bagh as we were earlier," he said.

May 30: A total of 513 domestic flights carrying 39,969 passengers were operated in India on Friday, Civil Aviation Minister Hardeep Singh Puri said on Saturday.

Domestic services resumed in India after a gap of two months due to the coronavirus lockdown. Indian carriers have operated a total of 1,827 flights till Thursday -- 428 on Monday, 445 on Tuesday, 460 on Wednesday and 494 on Thursday.

Puri said on Twitter on Saturday: "Day 5. 29th May till 2359 hrs. Departures 513. 39,969 passengers handled. Arrivals 512. 39,972 passengers handled." A departure is counted as a flight during the day.

During the pre-lockdown period, Indian airports handled around 3,000 daily domestic flights, aviation industry sources said.

In February, when the lockdown was not imposed, around 4.12 lakh passengers travelled daily through domestic flights in India, according to Directorate General of Civil Aviation (DGCA) data.

Airports in West Bengal, Andhra Pradesh, Maharashtra, Telangana and Tamil Nadu have been allowed to handle a restricted number of daily flights as these states do not want a huge influx of flyers amid the rising number of COVID-19 cases.

While domestic services resumed in Andhra Pradesh on Tuesday, they restarted in West Bengal on Thursday.

Though domestic flight operations across the country began on May 25, they could not be restarted in Kolkata and Bagdogra as the West Bengal machinery was involved in relief and restoration work after cyclone Amphan's devastation.

A total of 16 asymptomatic passengers on seven different flights, including 13 who travelled by IndiGo, have tested positive for COVID-19 since the resumption of domestic air services.
