After stopping Haj subsidy, BJP offers to send Christians to Jerusalem for free

Thiruvananthapuram, Apr 21: Not just in China, but in Kerala also robot is now playing a key role in the health workers' fight against COVID-19, thanks to the innovative spirit of a group of young minds and the support of the state Health Department.

Named "Nightingale-19", the robot is deployed to provide food and medicines among patients at the district coronavirus centre in Ancharakandi in Kannur district where a large number of cases have been reported.

The special display facility, attached to it, also allows patients to communicate with health workers and their relatives if necessary, the health minister's office here said.

Designed by the students of Chemberi Vimal Jyothi Engineering College with the support of the Health Department, the remote control-operated robot can carry food and water for at least six persons at a stretch.

The machine, which can travel up to one kilometre, distributes food, water and medicine in each room, a department statement said.

The robot would be disinfected after each use, it said.

Health Minister K K Shailaja inaugurated the new venture from here recently through the robot's video facility, the statement added.

Robots have been put to use in other parts of the country to help in the health workers' fight against COVID- 19.

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.

Lucknow, Mar 3: Two days after wife of Kafeel Khan, who is booked under the National Security Act, alleged that her husband faced a threat to life in Mathura jail, where he is lodged for anti-CAA protests, the District Magistrate claimed that Khan was 'fully secure' in the jail.

"Kafeel Khan, who has been booked under the National Security Act (NSA) for alleged inflammatory statements during an anti-CAA protest in Aligarh, is absolutely fine and fully secure in Mathura jail. Allegations of 'inhuman' treatment being meted out to him are baseless," Mathura District Magistrate Sarvagya Ram Mishra said on Monday.

Senior Superintendent of Mathura district prison, Shailendra Maitrey, said that Khan's condition is being monitored every half an hour and the report is written in the gate book. He said, his ECG is normal and blood pressure was also in control.

He said that Khan was demanding checkup from a cardiologist.

"Since no specialist is available in the government sector here, his request could not be complied with. However, the jail authorities have sent his request to chief medical officer and have asked him to make a specialist available," the jail official said.

He said Khan is in barrack, which is fully ventilated, and he shares it with 50-60 'good behaviour' prisoners.

It may be recalled that in a letter to the Chief Justice of Allahabad High Court, Additional Chief Secretary (Home), and Director General (Jail), Shabista Khan, wife of the jailed doctor, had alleged that her husband was being treated inhumanely in the jail.

She feared that an attempt could be made on her husband's life inside the jail. She had demanded adequate security for him and had urged that her husband should be kept away from active criminals lodged in the jail.

Khan was booked by Aligarh police on December 13 for delivering a provocative speech in Aligarh Muslim University (AMU) during an anti-CAA protest in the campus, a day earlier, and was arrested from Mumbai airport on January 29 by Uttar Pradesh special task force.

The Aligarh police had slapped the stringent National Security Act (NSA) against Khan on February 13 night, hours before he was expected to walk free from the Mathura jail, after he was granted bail by Aligarh's chief judicial magistrate on February 10.
