Bengaluru citizens' group moves SC to intervene in Cauvery case

Thiruvananthapuram, Apr 27: Kerala Chief Minister Pinarayi Vijayan on Sunday said the issue of return of Non-Resident Keralites (NRKs) to the state has been taken up with the Centre and the state government is awaiting a favourable response.

Vijayan said this in a meeting with Non-Resident Keralites over steps taken by the state government for those wishing to return to the state from foreign countries.

The Chief Minister announced that the Department of Non-Resident Keralites Affairs has opened online registration for such NRKs.

"Those returning should undergo screening at airports. All those returning should undergo mandatory home quarantine for 14 days.

Arrangements of isolation wards will be provided for those unable to go home," said Vijayan.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Managluru, May 13: Expressing regret over the inconvenience faced by the first batch of passengers from UAE that landed at Mangaluru International Airport last night, Dr C N Ashwath Narayan, deputy chief minister of Karnataka, today assured that all short comings will be addressed.

Addressing Kannadiga delegates from Saudi Arabia, Qatar, Kuwait and other countries through a video conference, Dr Narayan also assured that necessary steps will be taken by the Karnataka government to provide free quarantine facility for those who cannot afford private quarantine in hotels or guest houses. The video conference was organised by coastaldigest.com.

"The incontinence faced by passengers from Dubai at Mangaluru Airport have already been brought to my notice. All these shortcomings will be addressed. We will take appropriate steps to prevent the recurrence of such inconveniences," he said.

He said that the Karnataka government has already amended its standard operating procedure for international passengers to allow pregnant women to entre home quarantine if they test negative for covid-19. 

The problems faced by passengers at Mangaluru Airport last night include lack of staff to handle luggagues, lack of food and water, delay in arranging vehicle to transport passengers to quarantine centres and lack of free quarantine facility for those who cannot afford private quarantine facility. The next batch of repatriates will not face these problems, he said. 

Dr Narayan also promised to exert pressur on the union governmment to operate more flights to repatriate stranded Indians, especially Kannadigas from Saudi Arabia.

Prominent NRI commnity leaders Zakariya Jokatte, Naveen Bandary, Joy Fernandes, Shathosh Shetty Riyadh, Althaf Saqco, Shiekh Expertise and others participated in the video confernce.
