BJP central leaders back Yediyurappa: BSY regime will be stable, says Amit Shah

Bengaluru, May 29: A cost-effective state of the art glove box testing booth for swab collection was inaugurated by Karnataka Medical Education Minister Dr K Sudhakar at Victoria hospital.

Inaugurating the specially designed booth for safer, easier and quicker testing, Medical Education Minister Dr Sudhakar said that the portable booths can be used at border check posts and hot spots.

"The testing method involves the collection of samples from inside a box of aluminium and glass. The suspected corona virus-infected individual, whose samples are being taken, has to walk up to the booth and stand in front of the glass exterior. The healthcare worker inside the kiosk collects the sample and then, follows the sanitisation process before proceeding to take the next sample. The collection process, fully contactless, gets over in five minutes," the Minister said.

Dr Sudhakar also said: "This booth significantly reduces manpower requirement and the need for PPE kits. The main advantages of this procedure are that it needs fewer healthcare workers and strictly adheres to the norms of social distancing. 

The booth is low-cost. Each model costs about Rs 15,000-20,000."
It is also portable and can be mounted on a vehicle and transported to any location.

It can be particularly useful for collecting samples in hot spots and border checkpoints, he added. 

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mau/ Kalaburagi, Mar 26: Uttar Pradesh Police on Wednesday asked lockdown violators in Mau to do push-ups and squats as a punishment.
In Karnataka's Kalaburagi, police personnel punished the violators of the lockdown.
In his address to the nation on Tuesday, Prime Minister Narendra Modi announced a 21-day lockdown in the entire country effective from midnight to deal with the spread of coronavirus, saying that "social distancing" is the only option to deal with the disease, which spreads rapidly.
According to the Health Ministry, the total number of positive COVID-19 cases in India reached 606, including 43 foreign nationals.
