Babri case: Muslim board denies meeting Ravi Shankar for out of court solution

New Delhi, Jun 29: Delhi Chief Minister Arvind Kejriwal on Monday paid tribute to the senior doctor of city government-run LNJP Hospital who died battling COVID-19, saying the society has "lost a very valuable fighter".

The 52-year-old doctor served in the front line of the war against the pandemic at the government facility, and died of novel coronavirus infection in an ICU of a private hospital on Sunday.

"Dr Aseem Gupta, a senior doctor of LNJP Hospital succumbed to Covid yday. He was known for going out of his way to serve his patients. We have lost a very valuable fighter. Delhi salutes his spirit and sacrifice...," Kejriwal tweeted.

The chief minister also said in his tweet that he has spoken to Dr Gupta''s wife and "offered my condolences and support".

LNJP Hospital is a dedicated COVID-19 facility under the Delhi government. It recently completed 100 days of being declared a coronavirus facility.

"LNJP Hospital has displayed great fortitude in the face of acute challenges. It''s recovery rate is going up, death rate is reducing, ICU capacity is being ramped up - the hospital is saving so many lives," the chief minister said.

A condolence meeting to pay respect to Dr Gupta has been scheduled at 1 pm in the office of the Medical Director of the hospital, a senior official said.

The doctor, a consultant anaesthesiologist died at the Max hospital, Saket in south Delhi, a private dedicated COVID-19 facility.

"He was a front line anaesthesia specialist who contracted COVID-19 infection while on duty. He tested positive on June 6, when he had mild symptoms and was shifted to a quarantine facility. His symptoms aggravated on June 7 and he was admitted in the Intensive Care Unit of the LNJP Hospital," the LNJP Hospital said in a statement on Sunday.

He was shifted to Max Hospital, Saket on June 8 on his request, it said.

The doctor was battling the disease for the last two weeks at Max Hospital, where he succumbed to the illness on Sunday, the statement said.

He was Specialist, Grade I, in the Department of Anaesthesia at the LNJP Hospital, the statement said.

Several hundreds of healthcare workers have been infected with COVID-19 till date in Delhi.

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.

New Delhi, May 3: Union Health and Family Welfare Minister Dr Harsh Vardhan on Sunday said that India's COVID-19 mortality rate of 3.2 per cent is the lowest in the world and over 10,000 coronavirus patients have been discharged from hospitals after recovering from the disease so far.

"Today more than 10,000 COVID-19 patients have been discharged. Those still admitted at hospitals are on the road to recovery. If in last 14 days doubling rate was 10.5 days, then today it is around 12 days," the Minister told ANI after visiting Lady Hardinge Hospital.

"Our mortality rate of 3.2 per cent is the lowest in the world," he said.

With 2,644 more COVID-19 cases and 83 deaths in the last 24 hours, the number of people infected from coronavirus in the country has reached 39,980 including 1,301 deaths, said the Union Ministry of Health and Family Welfare on Sunday.

Currently, there are 28,046 active cases while 10,633 COVID-19 positive patients have been cured/discharged.
