Call for sacking of Indian-origin chef in UAE after 'anti-Islam' tweet

Dubai, Jun 5: A new set of coronavirus guidelines for UAE hotels has been published by the National Emergency Crisis and Disasters Management Authority.

The guidelines, released late Thursday, require all employees to be tested for Covid-19 before reopening, and to be re-tested every 15 days.

Hotels are expected to provide an infrared thermometer and thermal camera, with employee temperatures to be tested several times per working day.

Any guest or employee showing coronavirus symptoms will not be permitted to enter hotel facilities, the guidelines stress.

Hotels must also leave a 24-hour gap between guests leaving a room, and the next guests arriving.

Facilities such as restaurants, cafes, gyms, swimming pools and beaches in hotels will resume operation under a minimum capacity.

Customers must have their temperatures taken before they enter.

The working hours of restaurants and cafes will be from 6am until 9pm, allowing four people to sit at the same table with 2.5 metres left between tables. Menus must be sterilised after each use.

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.

Dubai, July 6: In an attempt to make a comeback in the tourism sector amidst managing covid-19 crisis, Dubai is all set to welcome holiday-makers from foreign countries from July 7.

It said those entering would have to present certificates to show they had recently tested negative for the coronavirus or would undergo tests on arrival at Dubai airports.

Reassuring tourists of several comprehensive measures to prevent the transmission of the pandemic, Dubai Tourism urged global travellers to make the city that boasts world class health and safety standards "a must-visit destination."

Dubai Tourism hosted a virtual forum for stakeholders and partners to share its industry outlook ahead of the city's reopening to international tourists.

The forum, which was attended by nearly 2,000 key executives from the aviation, travel and hospitality sectors and across tourism touch-points, provided a first-hand insight into current and post-pandemic strategies that will help accelerate tourism momentum and position Dubai as a safe global destination.

Helal Saeed Almarri, director general, Dubai Tourism, said that the city has put in place a robust strategy to manage the pandemic with the key priority being to safeguard the health and well-being of citizens, residents and guests.

Dubai, which saw a 5.1 per cent in tourist traffic to 16.73 million in 2019, remains top of mind for travellers and ranks high in global Internet search rankings for tourist destinations.

Dubai Tourism has launched marketing activities designed to convey positive messages about travel in today's environment, Dubai's preparedness, high standards of quality and safety, unique experiences that await visitors and also address traveller concerns across every touch-point in their journey.

The forum highlighted the preventive measures taken so far against Covid-19 that have further elevated the UAE's standing as one of the world's safest countries. The UAE is globally ranked No.3 in testing per million of population. It was also ranked No.3 in an international survey that assessed satisfaction with governments' response to the pandemic.

Over 350 influencers were also deployed to take the Dubai story in 14 different languages to a global audience spanning 18 markets, which yielded over 21 million engagements across multiple social media platforms.
