Jaipur's latest coronavirus case, an Octogenarian who travelled from Dubai

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.

Kolkata, Jun 29: Sweet-loving Bengalis have something to cheer about in COVID-19 time as the West Bengal government decided to come out with a "sandesh" which will contain honey from Sundarbans and increase immunity, an official said on Sunday.

Cotton cheese made from cow milk will be mixed with pure honey from the Sunderbans to prepare the "Arogya Sandesh" which will also have extracts of tulsi leaves, an official of the Animal Resources Development Department said.

No artificial flavours would be added to the sweetmeat which will be available in the department's outlets in the city and neighbouring districts, he said.

The sandesh will boost the immune system as a whole but it is not a COVID-19 antidote, the official said.

Sunderbans Affairs Minister Manturam Pakhira said the honey for making Arogya Sandesh will be collected from beehives in places such as Pirkhali, Jharkhali and other parts of the Sunderbans and it will be stored in a scientific manner.

The sandesh is expected to hit the shelves in another two months and the pricing will be within the reach of the common man, the animal resources development department official said.

Earlier this month, a reputed sweetmeat chain of Kolkata came out with an "Immunity Sandesh" claiming that it contains various herbs and spices such as haldi (turmeric), tulsi, saffron, and cardamom and Himalayan honey, which will boost immunity to fight novel coronavirus.

New Delhi, Jan 24: Under attack for doling out subsidies, Delhi Chief Minister Arvind Kejriwal on Friday said freebies in limited dose are good for the economy as they make more money available to the poor and boosts demand.

Opposition parties have been attacking the AAP-led Delhi government for giving "freebies" ahead of polls after it announced schemes like free bus rides for women and 200 units of free electricity.

"Freebies, in limited dose, are good for economy. It makes more money available to poor, hence boosts demand. However, it should be done in such limits so that no extra taxes have to be imposed and it does not lead to budget deficits," Kejriwal said in a tweet.

Slamming the BJP, Kejriwal said he is happy that the people of Delhi have forced the Saffron party to ask for votes on the basis of CCTVs, schools and unauthorised colonies.

Reacting to a tweet of the BJP Delhi in which Home Minister Amit Shah had asked how many schools have been constructed and cameras installed by the AAP government, Kejriwal said he is happy that Shah saw some CCTV cameras as earlier he had claimed that he could not find a single one.

"I am happy you saw some CCTV cameras. A few days back you said there was not a single camera. Take out some time we will show you our schools also. I am extremely happy that the people of Delhi have changed the politics by which the BJP has to ask for votes on CCTV, schools and raw colonies here," he said in a tweet.

Responding to Shah's allegation that he could not find WiFi in Delhi as promised by Kejriwal and that his battery drained out in the process, the Delhi chief minister said along with free WiFi they have also made arrangement for free charging points.
