Youth carries father's body in hand cart as hospital denies vehicle

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bangalore, Feb 1: Following the Directions from department of Health and Family Welfare, Govt of Karnataka, to set up Isolation ward for the admission and treatment of the Novel Coronavirus infected patients, Fortis Hospital, Bangalore has allocated 5 isolation beds, 4 at its Bannergatta unit and 1 at Cunningham Road Unit.

According to a statement issued here on Friday, Dr A Nagasubramaniam, Medical Director, Fortis BG unit said, “We are following the guidelines and protocols as suggested by Department of Health and family welfare and Rajiv Gandhi Institute of Chest Diseases in line with WHO guidelines for managing any suspected case. We will accordingly notify the health authorities.”

The management has been educating the hospital staff members, visitors and patients about the virus and the precautionary measures on a timely basis. A health advisory on Coronavirus has also been put up at the lobby and the canteen to educate the patient attenders, nurses and staff members, the statement added.

New Delhi, Jul 25: Nearly a year after Cafe Coffee Day founder V.G. Siddhartha's death, the probe committee appointed by the Board of Coffee Day Enterprises Ltd (CDEL) has given a virtual clean chit to private equity investors and the Income Tax Department who were named in his last letter.
The investigation report noted that Siddhartha may have felt "aversive behavioural stimulus" due to persistent reminders from the PE investors and other lenders.

"However, such reminders and follow-ups by the PE investors and lenders are not something which are beyond normal industry practices and we believe that PE investors were acting as per accepted legal and business norms," said that report.

It further said that the investigators were not provided with any documentary evidence to show any "advertent or inadvertent harassment" from the Income Tax Department.

It however, said that the financial records suggest a serious liquidity crunch which may have arisen due to the attachment of Mindtree shares by the IT Department.

Further, the probe revealed that MACEL, a private firm of Siddhartha, owes Rs 2,693 crore to Coffee Day Enterprises, which the report says, "needs to be addressed".

The Cafe Coffee Day founder's body was fished out of the Netravathi river in Karnataka by a group of fishermen on July 31 last year, a day after he went missing.

His last note raised several questions about the role of investors, and tax officials.

He had written: "Tremendous pressure from other lenders lead to me succumbing to the situation. There was a lot of harassment from the previous DG Income Tax in the form of attaching our shares on two separate occasions to block our Mindtree deal and then taking possession of our Coffee Day shares, although the revised returns have been filed by us. This was very unfair and has led to a serious liquidity crunch."

The massive shock to the industry and the country also led the government to assure that tax officials would not harass businessmen and the situation would improve.
