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 1: Air India's jumbo B747 plane, evacuating 324 Indian nationals from the novel coronavirus-hit Wuhan in China, landed here on Saturday morning, officials said.

The plane reached Delhi around 7.30 am, they said.

There were five doctors from Ram Manohar Lohia (RML) Hospital and one paramedical staff on board, said an Air India spokesperson.

The Indian Army has set up a quarantine facility in Manesar near Delhi to keep those evacuated from China's Hubei province.

Officials said they would be monitored for any signs of infection for a duration of two weeks by a qualified team of doctors and staff members.

"With 324 passengers, special flight has taken off for India from Wuhan. It may reach Delhi at 7.30am," said the Air India spokesperson at 1.19 am on Saturday.

The flight had departed from Delhi airport at 1.17 pm on Friday to evacuate Indian nationals from China, where more than 250 people - none of them Indian - have died due to novel coronavirus.

On Friday evening, the Air India spokesperson had stated that another special flight may take off from Delhi airport on Saturday to evacuate Indians from Wuhan.

The death toll from the novel coronavirus outbreak in China has risen to 259 with total confirmed cases surging to 11,791 amid stepped up efforts by a number of countries to evacuate their nationals from Hubei province, the epicentre of the virus, officials said on Saturday.

About Friday's flight, the spokesperson had said earlier during the day, "A team of five doctors from RML hospital, one paramedical staff from Air India, with prescribed medicines from doctors, masks, overcoats, packed food are in the aircraft. A team of engineers, security personnel are also there in this special aircraft. Whole rescue mission is being led by Captain Amitabh Singh, Director (Operations), Air India."

The spokesperson had added that there were five cockpit crew members and 15 cabin crew members on Friday's flight.

Before departure at Delhi airport, Air India Chairman and Managing Director Ashwani Lohani had said, "No service will take place in the plane. Whatever food is there will be kept in seat pockets. As there will be no service, there will be no interaction (between cabin crew and passengers)."

"Masks have been arranged for the crew and passengers. For our crew, we have also arranged a complete protective gear," he had added.

"Total five doctors from the Health Ministry are also going... The plane will be there (at Wuhan airport) for 2-3 hours," Lohani had said.

Air India has done such evacuations earlier also from countries such as Libya, Iraq, Yemen, Kuwait and Nepal.

New Delhi, May 27: As per the prediction from the IMD, severe heatwave conditions continued in several parts of north India with Delhi recording the country’s second-highest temperature at 47.6 degrees Celsius.

In Delhi, the mercury soared to 47.6 degrees Celsius in Palam area and most places recorded their maximum temperatures six notches above normal. The Safdarjung Observatory, which provides representative figures for the city, recorded a maximum of 46 degrees Celsius.

The last time when the mercury at the Safdarjung weather station touched the 46-degrees-Celsius mark was on May 19, 2002.

The IMD said the weather stations at Lodhi Road and Aya Nagar recorded their respective maximum at 45.4 degrees and 46.8 degrees Celsius.

In its earlier forecast, the IMD has said that dust storm and thunderstorm with winds gusting up to 60 kilometres per hour is likely over the National Capital Region on Friday and Saturday.

On the other hand, severe heatwave conditions prevailed in several parts of Rajasthan on Tuesday, with the mercury touching 50 degrees Celsius in Churu district.

The IMD said this is the second-highest maximum temperature recorded in Churu district in the month of May in the last 10 years.

Other areas such as Bikaner, Gangangar, Kota and Jaipur recorded maximum temperatures of 47.4 degrees Celsius, 47 degrees Celsius, 46.5 degrees Celsius and 45 degrees Celsius, respectively.

In the adjoining areas of Chandigarh, the severe heatwave condition continued in Haryana, Punjab with Hisar being the hottest place in the region at 48 degrees Celsius.
