I-T raids on close aides of two more Congress MLA candidates

Bengaluru, Apr 28: Former Chief Minister Siddaramaiah on Tuesday demanded that the Karnataka government announce a "special package" for unorganised sector workers, street vendors and autorickshaw drivers, among others, all daily wagers whose lives are affected by the COVID-19 lockdown. "..a special package needs to be announced to this section of people, this is the demand," Siddaramaiah, who is also Leader of the Opposition in the state assembly, told reporters here.

Alleging that the government has failed to control the spread of coronavirus, he said it is the government's responsibility to take care of the basic needs of those from the unorganised sector, whose lives have been impacted by the lockdown. "It is the duty of the government and they should do it immediately. The package should also be announced. I will hold discussions with leaders of other opposition parties like JD(S), CPI, CPI(M) and BSP in this regard and also on trouble faced by farmers," he added. Alleging discrimination in supply of food packets and ration kits, Siddaramaiah said it was being supplied properly only in constituencies represented by BJP legislators.

"Politics is being played out in supply of food materials to the needy, keeping corporation elections in mind.... We don't want to do politics at this point in time as there is lockdown. If things continue to be the same after the lockdown ends, we will protest on the streets," he said.

Siddaramaiah on Tuesday interacted with representatives of auto rickshaw and cab drivers, street vendors, barbers, unorganised workers organisations, among others, to understand the difficulties faced by them during the lockdown and to know whether help from the government has reached them. He said most of them don't have work and it has become difficult for them to lead their normal lives.

They raised several issues like auto and cab drivers being unable to pay road tax and EMI, he said, adding that he would write a detailed letter to the Chief Minister in this regard The former Chief Minister pointed out that there is about 21 lakh registered organised workers, 1.32 crore lakh unorganised workers and also agriculture labourers in the state.

"Among organised workers only 12.5 of the 21 lakh are said to be getting Rs 2000, that too from the Employees Welfare Fund, while others could not get any money, citing reasons like they have not renewed it," he said.

On the other hand, unorganised sector workers don't get money and were also not getting proper food or ration kits, he alleged Though the labour department claimed that it was supplying one lakh food packets and 1.5 lakh ration kits, as also corporations, there were leakages and it was not reaching the beneficiaries properly, he said.

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
