Hindu Mahasabha celebrates Gandhiji's death anniversary

Bengaluru, Apr 12: The Karnataka government is studying in-depth the consequences of the possible relaxation of lockdown norms after April 14 and plans to come out with a clear roadmap in a day or two, a key Minister said on Sunday.

Medical Education Minister K Sudhakar, who is in charge of all matters related to COVID-19, told PTI that the pros and cons of any decision that the Government intends to take is being looked at in detail.

"We are trying to understand how the situation would be of any action that we intend to take. We need to foresee the repercussions or results of our action. That we have to keep it in mind and make a decision. After-effects of the decisions we intend to take, that is more important, he said. You will have clarity (on the possible relaxation of lockdown norms) in a day or two. For everything (government decisions) we will give the reasoning for what action we would like to take; with the reasoning, we will give a decision," the Minister added.

Government sources said some relaxation in liquor sales, stopped during the lock-down period, is likely after the ongoing 21-day national clampdown ends on April 14. Twelve of the state's 30 districts remain free from the COVID-19 pandemic. Till Saturday, Karnataka reported 215 COVID-19 positive cases, including six deaths and 39 discharges.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, May 26: After Yogi Adityanath said that no state can take manpower from Uttar Pradesh without his government's permission, Karnataka Pradesh Congress Committee (KPCC) president DK Shivakumar on Tuesday termed the Uttar Pradesh Chief Minister's move as "unconstitutional" and "against the right to freedom of movement."

"Uttar Pradesh Chief Minister Yogi Adityanath's move to restrict hiring people of Uttar Pradesh is unconstitutional and goes against the right to freedom of movement. Mr Yogi, please note that UP is not the private property of your govt. The people of Uttar Pradesh don't need your government's permission to work anywhere in India," Shivakumar tweeted.

"Mr Yogi doesn't understand the basic rules of governance in a democracy. Such actions lack common sense and will only make the people of Uttar Pradesh suffer more. When it's convenient for BJP, it's One Nation, when it's not, it's different states and different people. Heights of hypocrisy," he added.

Adityanath had on Monday said that the state government will provide social security and insurance to labourers and no state can take manpower from Uttar Pradesh without his government's permission.

"If any state wants manpower, they cannot take our people from the state without our permission as there were reports of misbehaviour with them in other states. We are taking full responsibility for labourers' social security. We will provide every kind of security to them including insurance. Wherever they will go, we will always stand by them," Yogi said.

The Chief Minister said that skill mapping is being done in Uttar Pradesh and a commission will be set up for labourers to ensure employment for them.

On Sunday, Adityanath had ordered the formation of a 'Migration Commission' for the purpose of providing the workers, who have returned to the state during the lockdown phase, with employment suited to their skills.
