Dubai Ruler dances with joy after Thunder Snow wins Dubai World Cup

New Delhi, Jul 6: India's COVID-19 tally neared the 7 lakh mark with 6,97,413 cases after 24,248 new cases were reported in the last 24 hours, said the Union Ministry of Health and Family Welfare.

As per the Health Ministry, there are 2,53,287 active cases in the country while 4,24,432 patients have been cured or discharged. While one patient has migrated.

425 new deaths were reported in the last 24 hours in the country due to COVID-19, taking the number of patients succumbing to the deadly virus to 19,693.

As per the Health Ministry, Maharashtra continues to be the most impacted state from the infection with 2,06,619 cases and 8,822 fatalities due to the virus. Tamil Nadu in second place has a total of 1,11,151 cases and 1,510 fatalities.

The national capital's COVID-19 cases are also nearing the 1-lakh mark with 99,444 coronavirus cases and 3,067 deaths.

The total number of samples tested up to July 5 is 99,69,662 of which 1,80,596 samples were tested yesterday, informed the Indian Council of Medical Research on Monday. 

Abu Dhabi, Jun 2: The United Arab Emirates on Monday recorded 635 new coronavirus cases, taking the total number of infections in the country to 35,192, the UAE’s Ministry of Health and Prevention said in a statement carried by state news agency WAM.

The new cases were detected after the health authorities conducted 30,147 additional COVID-19 tests citizens and residents.

The ministry also announced that 406 more patients have fully recovered after receiving the necessary medical care, raising the total number of recoveries in the country to 18,338.

The announcement was made during the regular media briefing held in Abu Dhabi, wherein Dr. Amna Al Dahak Al Shamsi, official spokesperson for the UAE government, provided an update on coronavirus-related developments and measures taken to mitigate its impact.

During the briefing, Dr. Al Shamsi also announced the death of two patients from COVID-19, taking the total number of deaths in the country to 266.

"The number of COVID-19 cases still receiving treatment now stands at 16,588 from different nationalities," she added, noting that more than 650,000 COVID-19 tests have been conducted over the past two weeks.

"Since the onset of the crisis, the UAE has focused on select segments of society, primarily the elderly and patients with chronic diseases, in order to ensure they survive the crisis," she added.

"We believe it is particularly morally important to support and stand by them, provide them with their daily needs, and keep them from harm’s way," she added.

Dr. Al Shamsi asserted that all precautionary measures announced, including the updated fines and penalties, will be enforced against violators, including citizens and residents.

"The law does not differentiate between citizens and residents. We are living in one homeland, which is for all of us," she continued.

"Your safety and health are a priority. We must comply with all precautionary measures. Though restrictions have been relaxed, caution must continue to be exercised."

Dr. Al Shamsi also warned, "Recklessness may undermine the efforts made by our frontline defenders. It is the responsibility of every individual to support protective efforts to ensure the safety of all."

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.
