Modi's second state visit to UAE begins

New Delhi, Feb 1: India on Friday banned the export of personal protection equipment such as masks and clothing amid a global coronavirus outbreak.

It did not give a reason for the ban but it reported its first case of the new coronavirus on Thursday, a woman in Kerala who was a student of Wuhan University in China.

The central Chinese city of Wuhan is the epicentre of the outbreak, and the virus has since spread to more than 9,800 people globally and killed 213 people in China.

Several Indian citizens living in Wuhan will arrive in India by plane on Saturday and be taken to a quarantine centre on the outskirts of the capital New Delhi.

India, the world’s second most heavily populated country after China, has taken measures to ensure that all people arriving from China report to health authorities.

Dubai, May 3: Over 150,000 Indians in the UAE, who wish to return home amid the coronavirus lockdown, have applied through the online registration process to the Indian missions here, according to media reports.

The Indian missions in the country last week opened online registration for the expatriates who wish to fly back home after getting stuck in the country amidst the lockdown due to the coronavirus pandemic.

As of 6 pm on Saturday, we received more than 150,000 registrations, Consul General of India in Dubai Vipul told the Gulf News on Saturday.

A quarter of them want to return to their homeland after losing their jobs, he said.

According to a report in the Khaleej Times on Sunday, about 40 per cent of the applicants who have registered are blue-collared workers and 20 per cent are working professionals.

"Roughly 20 per cent have suffered job losses and about 55 per cent of the total applicants are from Kerala," Neeraj Aggarwal, Consul, Press, Information, Culture was quoted as saying in the report.

Aggarwal said that the figures would change as they are expecting registrations from workers from other states, including Telangana, Uttar Pradesh, and Bihar.

About 10 per cent of the applicants are visit and tourist visa holders who got stranded here due to the ongoing lockdown in India.

India extended the ongoing lockdown by two weeks from May 4 to contain the spread of the coronavirus that has affected nearly 40,000 people in the country.

Aggarwal said that a small number of the applications constitute those from pregnant women and other medical cases.

Since the online registration process was launched, the Consulate's website crashed several times due to the heavy rush of applicants wishing to register to fly back home.

The site has been working fine now though it took a lot of time for it to stabilise in the initial phase due to the heavy traffic, the counsel general said.

He said that the missions here have not yet received any information from the Indian government about the mode of transport of the stranded citizens, the prices of the tickets or how the COVID-19 test results of applicants would be assessed for their journey.

There are high-level discussions going on regarding these things, he said in the report.

Meanwhile, Norka (The Non Resident Keralites Affairs) said it has received a total of 398,000 applications from Keralites across the globe who wish to return home.

"Of which, the highest numbers are from the UAE. At least 175,423 applicants have signed up from the UAE," Norka said in an official statement on Saturday.

It also received 54,305 registrations from Saudi Arabia, 2,437 from the UK, 2,255 from the US, and 1,958 from Ukraine from those who wish to return to India, the Khaleej Times reported.

The coronavirus has infected 13,599 people and claimed 119 lives in the UAE, the Ministry of Health and Prevention said on Saturday.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.
