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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, Apr 26: After directions from Karnataka government, migrant labourers are being sent to their native villages in batches by hiring as many as 60 buses.

Divisional Controller of Mangaluru KSRTC Division S N Arun said on Sunday that 100 buses from Mangaluru and Puttur ferried stranded labourers on Saturday. Buses were disinfected before the journey.

Buses also left from Dharmasthala, Bantwal, Puttur and Sullia to different destinations. In adherence to social distancing rules, each bus left with 20 to 22 labourers.

Bengaluru, Feb 19: Karnataka Chief Minister BS Yediyurappa is facing major dissent within the party and the BJP MLAs held a meeting on Tuesday night at former Chief Minister Jagdish Shettar's residence to discuss the functioning of Yediyurappa-led government, said BJP sources.

According to BJP sources, some of the unhappy BJP leaders and MLAs met last night at Shetter's place and expressed that they are not satisfied with Yediyurappa's leadership.

Last night's meeting shows that party leaders are looking to bring down Yediyurappa from the Chief Minister's post by sending a clear message to the high command that Yediyurappa is incapable of continuing as the CM, said BJP sources.

Other sources in BJP have also asserted that BJP leadership in Karnataka is looking for a "leader" who can lead the party in upcoming elections which is going to be held after three years. At this point of time, it's crucial for BJP to promote second-line leadership.

Meanwhile, a letter is being circulated in the BJP party forum and over social media against Chief Minister Yediyurappa's leadership.

It looks like the same team which is unhappy with Yediyurappa's leadership is trying to convey the same message to their high command. The letter which is being circulated says to be written by one of these leaders' groups against Yediyurappa and his son Vijayendra.

On this, Congress leader Ramalinga Reddy told media, "Maybe the letter is written by the same MLAs because after the expansion of Karnataka cabinet so many leaders from BJP were kept out."

"There is a lot of discontent among BJP MLAs that the ones who have toiled for the party day and night have been neglected from the cabinet expansion. This will definitely result in destabilisation in the government," said Eshwar Khandre, KPCC Working President.

Now party high command needs to look into Karnataka leadership to manage the government in the state.

"Now BJP leadership in Karnataka and Delhi need to look into the matter and need to solve the issue after cabinet expansion," said a BJP leader.
