Does it behove Rahul to label all Modis as thieves: PM

Kochi, Jul 11: Johnny Paul Pierce's five-month stay in Kerala has been a soul-soothing experience for 74-year-old US citizen. He now wants to spend the rest of his life here.

"Kerala is a beautiful place to live in. This is my fifth trip here. I usually stay here for six months. It is such a magical place to be and I want to share that with people from the US," Pierce told ANI.

He came to India on February 26 on a tourist visa and is staying at Kandanadu in Kochi.

According to Pierce's Advocate, his tourist visa is valid up to January 26, 2025. But on this visa, he can only stay consecutively for 180 days.

The guidelines of the Indian government permit continuous stay for only 180 days for foreigners on tourist visas. His 180 days were set to expire on August 24, which the Foreigner Regional Registration Office (FRRO) extended to August 30.

The US citizen has approached the Kerala High Court seeking to convert his tourist visa into a business visa. The petition will be considered next week.

Pierce has sought a directive to the government to permit him to apply for the conversion of his tourist visa into a business visa and also to extend his stay, without having to leave the country.

"I am making a petition for an extra 180 days to stay. And I would also like to get a business visa in order to begin a tour company to bring people from the US to Kerala after the coronavirus. I wish my family could also come here. I am very impressed with what's is happening here. People in the US don't care about COVID-19," he said.

He talked about the risk of going back to his home country saying, "There are only 27 deaths in Kerala and in the US there over 1.3 lakh deaths. I do not want to go back to the US. I am 74 years old and I am at risk. This is a very safe place for me. I hope India embraces and allows me to stay."

"There's chaos in the US due to COVID-19 and government is not taking care like India. I want to stay here," he added.

Pierce further talked about his future plans, saying that if he is allowed to stay, he would like to lease a small resort and make a retirement community, which will be a COVID free zone.

Lastly, he made an appeal to the Indian government to let him stay in India saying that "all the immigration rules were made before COVID-19."

"There should be special consideration for people like me," he added.

Global health experts on Wednesday said novel coronavirus is here to stay for more than a year and called for aggressive testing to prevent its spread.

In an interaction with Congress leader Rahul Gandhi, health experts Professor Ashish Jha and Professor Johan Giesecke talked about the COVID-19 pandemic as part of the series being aired on Congress social media channels.

While Jha exuded confidence that a vaccine will be available in a year's time, Prof Giesecke said India should practice a lockdown that is as 'soft' as possible, as a severe lockdown will ruin its economy very quickly.

"When the economy is opened up after lockdown, you have to create confidence among people," Harvard health expert Ashish Jha told Gandhi.

Jha is a professor of Global Health at TH Chan School of Public Health and Director, Harvard Global Health institute.

He said coronavirus is a '12-18 months' problem and the world is not going to be free of this till 2021.

The expert also called for the need for aggressive testing strategy for high-risk areas.

Gandhi, while interacting with the experts, said life is going to change post COVID-19.

"If 9/11 was a new chapter, this will be a new book," he remarked.

Professor Johan Giesecke, former chief scientist, European Centre for Disease Prevention and Control said India should have a 'soft lockdown'.

"The situation that India is in, I think, you should have a soft lockdown, as soft as possible," he said.

"I think for India, you will ruin your economy very quickly if you have a severe lockdown. It is better, skip the lockdown, take care of the old and the frail...," he noted.

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.
