Help poor, needy by not cutting their salaries: Karnataka CM

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

As part of the Indian Overseas Congress Mera Bharat Mahaan NRI Series, a Facebook live Global Conference was facilitated by Dr Arathi Krishna, Dy. KPCC NRI Chairman and Mr. Mohammad Mansoor President IOC Bahrain on 30th May, 2020.

In the one and half hour live interaction, questions and answers were addressed by DK Shivakumar, President of PCC Karnataka and attended by hundreds of participants, accumulating an impressive 300K people viewing the live broadcast across the globe.

The event was inaugurated with a welcome address by the inspiring and innovative IOC chairman Sam Pitroda followed by the motivational speech of AICC Secretary Shri Himanshu Vyas, IOC US President Mr. Mohinder Singh Gilzian and former KPCC NRI Dy Chairman Dr. Arathi Krishna by whom Shivakumar was introduced.

The event was remarkably successful with maximum interaction of global congress family members and straight forward answers by Shivakumar. 

He emphasized on the present political issues in India and the Indian government's negligence in handling the crisis related to Covid-19 and the indefinite lockdown. He added at present, that the Congress is playing a frontline, constructive role by addressing and articulating the Covid-19 issues and offering critique-based solutions to the government as a responsible opposition party.

The insightful meeting covered the congress strategy and the rebuilding of the KPCC, as well as discussed counter corrupt and hatred politics of current regime along with the role of constructive opposition, etc.

IOC Bahrain President Mr. Mohammad Mansoor thanked IOC Chairman Sam Pitroda, AICC Secretary  Himanshu Vyas for their role in strengthening the party and motivating the team; former KPCC NRI Dy Chairman Dr. Arathi Krishna for introducing the guest; IOC global IT Cell Chairman Manoj Shinde, along with Dananjay and Vinay for professionally managing the event;  IOC US President Mohinder and  Karnataka Chapter President Gauri Shankar for emphasizing the guest of honour; Ms Sofiya Sharma and Ms Vijya Nadela for beautifully moderating the event and all the distinguished guests and Presidents of IOC and KPCC wing Leaders from Saudi Arabia, Bahrain, Kuwait, UAE, Germany and other countries who were present on the online meeting and especially  Mr. Althaf,  PA to DKS and Mr. A.N.Nataraj Gowda in charge of KPCC IT Cell for helping facilitatethe online meeting.
