PM says lockdowns not being taken seriously; Centre tells state to get tougher

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.

More and more Indians have become better prepared in the last one month, as far as stocking of their ration, medicine or money is concerned, according to the IANS-CVoter COVID-19 Tracker.

With the second leg of the lockdown half way through and Prime Minister Narendra Modi saying it's a long haul, 57.2% respondents said they have less than three weeks of stock while 43.3% said they have a stock that will last beyond that

However, if one breaks into weeks, most respondents said they are prepared for a week's time. 24.5% respondents said they have ration, medicine or money to last a week. This is closely followed by 21.9 % respondents saying they are ready for a month.

Meanwhile, 20.4 % said they are ready for a couple of weeks. There are 15.8 % who said they are ready for more than a month with food, ration and medicine. A tiny 5.6 % said they are ready with three weeks of stock.

However, there is 12.3% who still seem to live on the edge with less than a week's preparation.

But, the biggest takeaway from the IANS-CVoter COVID-19 Tracker is that in the last one month, a massive segment of society realised that the fight is long and the preparation should also be to last that long.

o put things into context, on March 16 when the tracker started, a whopping 77.1% said they have stock to last for less than a week. More than a month later on April 21, that number jumped to just 12.3%, which essentially means, people have become better prepared for a long-hauled lockdown period.

Similarly, on April 21, a sizable 21.9% respondents claimed they are ready with ration and medicine that will last them a month. On March 16, not even one respondent could claim they have a month's stock. In fact till March 22, just ahead of the announcement of the first lockdown, no respondent the IANS-CVoter tracker said that they have a month's preparation.

Similarly, when the tracker started, 9.9% said they simply ‘don't know'. As on April 21, that number is a big zero.
