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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Apr 27: A 57-year-old man died of COVID-19 in Kalaburagi on Monday taking the fatalities due to the virus in Karnataka to 20.

"One more person died due to COVID-19 in the state. The 57-year-old person was tested positive for coronavirus on April 21," Medical Education Minister Dr K Sudhakar tweeted on Monday evening.

The minister said he was admitted to the Gulbarga Institute of Medical Sciences with respiratory problem.

He was also suffering from severe liver related ailments.

"With this five deaths have taken place in Kalaburagi district due to the virus," the minister added in his tweet.

The first COVID-19 death in the country was reported from Kalaburagi in March.

Bengaluru, Jan 5: A day after senior Congress leaders in Karnataka met to build consensus for the way ahead, the race for the post of KPCC President hotted up on Sunday with aspirants and their supporters stepping up efforts to secure the coveted posts.

Senior leader D K Shivakumar, seen as a frontrunner for the post, met former Chief Minister Siddaramaiah at his residence amid reports that he was lobbying in favour of one of his confidants.

Meanwhile, another senior party legislator Satish Jarkiholi made it clear he was capable of discharging the responsibility if the high command asked him to do so.

Also, loyalists of senior leader and former Minister Ramalinga Reddy came up with social media posts, pushing forward his name for KPCC President.

Congress Legislature Party leader Siddaramaiah and state Congress chief Dinesh Gundu Rao quit their posts after the party fared poorly, winning only two of the 15 seats in the bypolls while it had held 12 of them.

According to party sources, though Siddaramaiah is likely to retain the position of Leader of Opposition, the CLP leader post may be given to some one else.

The sources also said replacement of KPCC President was most likely as Dinesh Gundu Rao's resignation could be accepted.

Shivakumar is seen as the frontrunner for the KPCC President post and has already held discussions with high command in this regard.

His meeting with Siddaramaiah, who is expected to travel to Delhi soon to hold discussions with the high command, assumes significance amid reports that the former chief minister was favouring one of his confidants for the post.

Shivakumar during the meeting sought Siddaramaiah's cooperation for his appointment to the coveted post, with a promise to work under his leadership, sources said.

However, speaking to reporters after the meeting, Shivakumar said he had worked under Siddaramaiah as legislator and Minister, and there was nothing special about the nearly two-hour-long meeting.

"...Im not a competitor for any post, I won't ask for any post, that time is over. I'm a karyakarta of the party and will work as karyakarta," he said in response to a question, adding he will abide by the party's decision.

On the other hand, Congressleader andYamakanamaradi MLASatish Jarkiholi said he was ready to take up the responsibility if the party high command decides so.

"It has been decided to cooperate and work under the leadership of anyone, whom the party high command decides (as President). Let's see, it is for the high command to decide (who will be KPCC President)," he said.

In response to a question from reporters in Belagavi if he was aspiring for the post, Jarikholi said, "I havent asked, but if given I will manage it efficiently..."

Meanwhile, loyalist of seven-time Congress MLA Ramalinga Reddy, came up with a social media post, demanding KPCC President post for the leader.

"Seven-time @INCKarnataka MLA and former Home Minister Sri @RLR_BTM for #KPCC President. #Congress #Karnataka #RamalingaReddy #BTMLayout #BBMP #Bengaluru," former Mayor of Bengaluru City and a close confidant of Reddy, B N Manjunatha Reddy tweeted.

Last year during the political turmoil faced by the coalition government, Ramalinga Reddy had threatened to resign, unhappy at being sidelined in the party.

He had later decided to stay with the Congress after the high command intervened.

With a virtual vacuum in the state Congress following the resignation of its top leadership after the rout in the recent Assembly bypolls, senior party leaders had met here on Saturday with an aim to build a consensus for the way ahead.

According to sources, the meeting was convened after instructions from the high command to iron out differences and build consensus on taking the party forward and regarding appointments to key posts, before coming to Delhi for discussions.
