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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 19: A public interest litigation (PIL) has been filed in the Karnataka High Court, seeking a stay on Anand Singh functioning as Minister of Forests, Environment and Ecology contending that there are criminal cases filed against him by the Ministry.

"A stay be granted prohibiting Anand Singh from functioning as the Cabinet Minister for the Ministry of Forests, Environment and Ecology. Any other order that the Honourable Court may deem fit in the interest of justice and equity," the PIL prays.

The petition, filed by advocate Vijay Kumar, said that the Chief Minister has allocated the portfolio of the Ministry of Forests, Environment and Ecology to Singh without considering the fact that there are several criminal faces filed against him by the Ministry.

It said that the allocation of the Ministry of Forests, Environment and Ecology portfolio to Singh is in the conflict of interest.

"The holding of the post of Cabinet minister for the Ministry of Forests, Environment and Ecology is against public interest and completely in conflict of interest as he has business for which the subject Ministry is the overseeing authority and further he will also have access to the case files which again is in conflict of interest," the PIL said.

PIL adds that "it is pertinent and absolutely necessary" to deny the incumbent from accessing files related to his cases and from taking any decisions which may provide him with pecuniary benefits through his businesses.

Mangaluru, May 8: Dr Arathi Krishna, former deputy chairman of Karnataka NRI Forum, today called on Karnataka chief secretary Vijaya Bhaskar and urged him to exert pressure on the Centre through chief minister to expedite evacuation of Kannadigas stuck in Saudi Arabia amidst covid-19 lockdown. 

She also conveyed the message from labourers in Gulf countries requesting for free quarantine facility upon their arrival. Positively responding to the demand, Mr Bhaskar said that free quarantine facility will be arranged at BSF base in Bengaluru apart from paid quarantine facility in different hotels and guest houses.

Dr Arathi Krishna told coastaldigest.com that she also spoke to the officials in-charge of Gulf in the Ministry of External Affairs  and requested them to take necessary steps to add more special flights from Gulf countries to Karnataka. 

The officials have promised to consider operating flight from Riyadh to Mangaluru via Dammam in the second wave of evacuation, the schedule of which is expected to be announced in a few days, she said.
