Modi govt to sell Air India, Bharat Petroleum by March 2020

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, May 5: After Congress delegation was denied to donate a cheque of Rs one crore to ensure free transportation to migrants, Karnataka Pradesh Congress Committee (KPCC) president DK Shivakumar said that Congress party can go anywhere and help anyone they want and BJP leaders must understand what constitutional rights are.

Earlier on Monday, Karnataka Deputy Chief Minister who holds the transport portfolio, Lakshman Savadi suggested the Congress delegation for donating at least Rs 150 crore to the Chief Minister's Relief Fund instead of handing over a cheque of Rs one crore as a donation in order to bear the transportation fare of the migrants.

While reacting to Deputy CM and other BJP leaders' comments, Shivakumar said, "BJP leaders must understand what constitutional rights are. Who are these BJP leaders? They are now entering to help migrant workers after RSS guidelines. They must understand that we are a party and we can go anywhere and help anyone we want."

Congress leaders on Monday met Savadi to handover a cheque of Rs one crore in order to donate money for the migrant workers' transportation.

However, Savadi did not accept the cheque and suggested the Congress delegation to donate a bigger amount to the CM Relief Fund.

While addressing media after meeting the Congress leaders' delegation in the leadership of KPCC president, DK Shivakumar, Savadi said: "Congress has a history and its a wealthy party, still if Congress leaders want to donate, at least they must donate Rs 150 crores to the CM relief fund to fight COVID-19."

DK Shivakumar yesterday slammed the government and urged to depute free transport services to migrant workers, he asserted that Congress will donate money in this regard.

But the Managing Director of KSRTC denied to accept the cheque of Rs one crore and suggested the Congress delegation to meet transport minister or Chief Minister and donate to CM relief funds. Hence, today congress leaders met deputy CM Lakshman Savadi and tried to handover Rs one crore cheque which he did not accept.

After Congress leaders slammed the government and people criticised the decision of collecting bus fares, CM BS Yediyurappa ordered for free transport service to migrant workers.
