Exposed to online threats, Indian Navy bans use of social media

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, Jul 10: Nepal has banned all Indian news channels, except DD News, for alleged propaganda against the country.

Reports say that Nepal cable operators have stopped getting signals of Indian news channels.

Nepal government spokesperson Yuvaraj Khatiwada said: "We request all not to disseminate news that infringes sovereignty and self-respect of Nepalis. This includes the media of neighbouring countries. We might seek both political and legal remedies."

Earlier, Nepal has amended its map which show some Indian territory as part of it.

Nepal's parliament on June 13 adopted unanimously the Constitution Amendment Bill, paving the way for accommodating the updated political-administrative map, which includes Indian areas of Kalapani, Lipulekh and Limpiyadhura, in its symbol.

Beijing, Jun 11: Floods and mudslides in south China have uprooted hundreds of thousands of people and left dozens dead or missing, state media reported Thursday.

The bad weather has wreaked havoc on popular tourist areas that had already been battered by months of travel restrictions during the coronavirus outbreak.

Torrential downpours unleashed floods and mudslides that caused nearly 230,000 people to be relocated and destroyed more than 1,300 houses, official state news agency Xinhua reported, citing the Ministry of Emergency Management.

In southern Guangxi Zhuang Autonomous Region, six people were reported dead and one missing, Xinhua said.

Streets were waterlogged in popular tourist destination Yangshuo, forcing residents and visitors to evacuate on bamboo rafts.

The local government said more than 1,000 hotels had been flooded and more than 30 tourist sites damaged.

One owner of a family-run hotel told Xinhua that the guest rooms were submerged in one metre (three feet) of rainwater.

The extreme weather has dealt a hefty blow to the region's tourism sector, which is still reeling from the COVID-19 epidemic.

The emergency management ministry said there were direct economic losses of over 4 billion yuan (more than $550 million) from the flooding, Xinhua reported.

In Hunan Province, at least 13 people were killed in rain-triggered disasters, and another eight people are missing or killed in southwestern Guizhou province, according to the local emergency response departments, Xinhua said.

The heavy downpours began at the beginning of June and have led to "dangerously high water levels" in 110 rivers, Xinhua reported.

Further rainstorms are expected in the next few days across the south.
