New Delhi, May 21: As many as 5,609 new COVID-19 cases were reported in India in the last 24 hours, taking the total number of cases in the country to 1,12,359 according to the Union Ministry of Health and Family Welfare.

Out of the total cases, 63,624 are active cases, 45,300 patients have been cured/discharged or have migrated and 3,435 deaths have been reported.

With 39,297 cases in total, Maharashtra remains the worst affected state in the country, followed by Tamil Nadu (13,191 cases), Gujarat (12,537 cases), and Delhi (11,088 cases).

The nationwide lockdown imposed as a precautionary measure to contain the spread of coronavirus has been extended till May 31.

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.

Raipur, May 25: A union minister was caught on camera issuing threats to district administration officials in Chhattisgarh saying that she “knows how to take people to a room and beat them with belts"

Officials were taken aback when Renuka Singh, Minister of State for Tribal Affairs, delivered this dialogue during her visit to the quarantine centre at Balrampur, around 400 km from Chhattisgarh capital Raipur on Sunday.

Dilip Gupta, a resident of Balarampur district in Chhattisgarh, had accused the chief executive officer and tehsildar of the district panchayat of assaulting him in a quarantine centre in the area following a quarrel over shoddy facilities. Renuka Singh took cognizance of the matter and reached the quarantine centre to speak to Dilip Gupta.

The minister, on reaching the quarantine centre, received details of the incident from Gupta and his family and lashed out at the officials for "beating him up".

In a video, Renuka Singh is seen cautioning the officials to not think of BJP workers as "weak".

"Ye bhagwadhaari BJP ke karyakartao ko kamzor mat samajhna. Janpad me baithke aur aap tehsil me baith ke jo bhed-bhaav kar rahe hain BJP ke karyakartao ke sazth, bhool jaiye (Don't think of saffron-wearing BJP workers as weak. Forget the discrimination that you are showing towards BJP workers)," Renuka Singh said, lambasting the officials.

However, the minister did not stop there and went on to threaten the officials saying she knows how to 'thrash people with a belt'. 

"Andheri kothri me le jaa ke na main belt khol ke thokna jaanti hu bohot acche se (I very well know how to lock people in a dark room and thrash them with a belt)," Renuka Singh can be heard saying in a video from the incident.

Dilip Gupta, who was put under quarantine after he recently arrived from Delhi, had reportedly complained about the quality of food and basic facilities in the centre and had even uploaded a video on social media over the same after officials failed to address his issues.
