Warangal, Jul 22: Amid the COVID-19 pandemic, an outlet in Telangana's Warangal has started selling 'anti-corona' tea. The tea has become an instant hit with the locals as the beverage is laced with natural immunity-boosting ingredients.

"We sell tea named 'anti-corona'. It has natural immunity-boosting ingredients such as ginger, black pepper, cinnamon powder, among other things. A mixture of these ingredients boosts our immunity," Shiva, the owner of the tea shop said.

"Better immunity is needed to fight the coronavirus infection in the body. So we have started preparing this tea and selling it during the coronavirus pandemic," he added.

Prabhakar, a customer at the tea stall said, the tea was a "corona special tea," and it has Ayurvedic mixtures which help to boost the immunity of the human body.

"The tea is prepared after adding the Ayurveda mixtures to milk. This is good for your health. I, along with my family members and friends, come here every day. We drink this tea thrice a day," Prabhakar added.

According to the Union Health Ministry, there are 46,274 COVID-19 cases in Telangana. Meanwhile, India's coronavirus count stood at 11,92,915 on Wednesday morning.

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.

Kochi, Mar 30: Kerala High Court on Monday granted interim bail to the under-trial prisoners and remanded accused in the state till April 30 in view of the lockdown imposed to prevent the spread of coronavirus.

The court said that the accused should report to the local police station immediately after getting bail. Those released on bail must strictly follow the lockdown instructions, the High Court said.

"Those who have been convicted of imprisonment for less than seven years will get bail. Prison Superintendents will release the prisoners who are eligible. But regular offenders are not entitled to get bail," the court said.

After the bail period, the accused should appear in the respective trial courts, where a decision will be taken on their bail by the respective trial courts.

The Supreme Court had last week asked all state governments to release undertrial prisoners, who are facing charges attracting less than seven years imprisonment, to reduce overcrowding of jails amid the ongoing coronavirus scare.

So far, 194 confirmed cases of coronavirus have been reported in the state.

The country is under a 21-day lockdown to prevent the spread of coronavirus, which according to the Ministry of Health and Family Welfare has claimed the lives of 29 people and infected a total of 1071 people as on Monday morning.
