Thank you UCA: 'Saint of Letters' Harekala Hajabba enters new house

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

Bengaluru, Jul 21: Karnataka Chief Minister B S Yediyurappa on Tuesday said that everyone has to fight COVID-19 while maintaining a stable economy and lockdown is not the solution.

While briefing the media after a meeting with Health Minister B Sriramulu and officials here, CM Yediyurappa said, "There will be no lockdown from tomorrow, people need to get back to work, the economy is also very important. We have to fight COVID-19 while maintaining a stable economy. Lockdown is not the solution, now restrictions will be placed only in containment zones."

"People who came from Maharastra and Tamil Nadu added to the COVID-19 cases in Karnataka. Experts have suggested a 5T strategy - Trace, Track, Test, Treat and Technology. Our COVID warriors are working day and night to safeguard the people of the state, we have to maintain social distance, wear a mask while going out," he added.

CM Yediyurappa further said that more than 80 per cent COVID-19 cases in the state are asymptomatic.

"Five five per cent need ICU or ventilators, 11,230 beds are kept ready for the use of people including private hospitals, medical colleges. The real-time dashboard is ready to serve the people. Now onwards, test report will be given within 24 hours. SSLC exams were conducted successfully. More than 8 lakh students wrote exams in such a situation," he said.

Commenting upon the allegations of COVID-19 mismanagement labelled by opposition leaders, CM Yediyurappa said, "I request all the opposition leaders not to make unnecessary comments. I request Siddaramaiah, D K Shivakumar and others to suggest us valuably to fight corona together."

"We will give all the details which are required to D K Shivakumar, Siddaramaih, H D Kumaraswamy. Not even one-rupee corruption is done in COVID-19 management. We will give you all details. No official misused any funds, being opposition leaders, you have all rights to check documents, we will provide them," he added.

Taking to Twitter, Health Minister B Sriramulu said that the decision to raise the salary of 2,000 AYUSH doctors to Rs 45,000 was taken in the meeting.

"The decision to raise the salary of 2000 AYUSH doctors to Rs 45,000 was taken at a meeting chaired by our Hon. Chief Minister Shri @BSYBJP. Assurance has been given that the demand of private AYUSH doctors too will be reviewed and a decision regarding the same will be taken at the earliest. All doctors who were protesting for the same have withdrawn their resignations and reported to work," he tweeted.

Chikkamagaluru, Feb 21: Alleged Bharatiya Janata Party supporters threw stones at Amulya Leona’s father’s house at Gullagadde near Koppa on Thursday night, after she was charged for making objectionable remarks at a public programme in Bengaluru.

Amulya Leona’s father Wazi said that the incident, which left window panes and doors damaged, took place at around 7.30 p.m. “They are all BJP supporters. They were in a group. I have complained to the police with the names of a few who led the group,” he said.

Three policemen have been deployed at his house since Thursday night.

Amulya Leona, a B.A. student, was charged with sedition after she raised pro-Pakistan slogans at a protest against the Citizenship (Amendment) Act in Bengaluru.

Mr. Wazi, who owns a two-acre areca plantation and runs a poultry farm, said he condemned the statement made by his daughter and he would not make any attempts to get her bail. “Let the law take its course. I cannot approve of her statement,” he said.

He said he had cautioned his daughter against getting involved in protests. “I told her to complete studies first and later she could fight for poor people. But what she said yesterday is not acceptable. I don’t know what made her so. I hope a probe would bring out who prompted her to make such statements,” he said.

Mr. Wazi said he has been politically active for several years, and had earlier worked for former education minister H.G. Govinde Gowda. He then shifted to the BJP and worked in support of D.N. Jeevaraj, who represented Sringeri constituency last time, and current Udupi-Chickmagaluru MP Shobha Karandlaje. “I have worked for the BJP in the past. As Govinde Gowda’s son contested on JD(S) ticket for Sringeri seat, I supported him”, he said.

Meanwhile, a video clip that went viral on Thursday night showed a group of Bajrang Dal activists compelling Mr. Wazi to shout ‘Bharat Mata ki Jai’. “I have no hesitation in raising ‘Bharat Mata Ki Jai’ slogans,” said Mr. Wazi, adding that his statement was taken forcibly. “I am a patriot. Many writers, activists and politicians have come to my place over the years,” he said.
