Yeddyurappa hits out at Karnataka’s Anti Corruption Bureau

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Apr 11: The coronavirus-driven lockdown will continue for another 15 days, but relaxations will be allowed in a graded manner, Karnataka Chief Minister B S Yediyurappa said after a four-hour-long video conference with Prime Minister Narendra Modi on Saturday.

“Agriculture and industrial sectors will be given relaxation. Government offices will be allowed to work with partial strength. But the PM said detailed guidelines will be issued in two days,” Yediyurappa said, briefing reporters. 

“Importantly, the lockdown for the next two weeks will be different than how it was in the past three weeks. The Centre, keeping in mind economic activities, especially agriculture, industry and employment of labourers, the Centre will tell us what needs to be done,” the CM said.
 
According to Yediyurappa, PM Modi told all chief ministers that the next 2-3 weeks will be critical. “The next few weeks will decide whether or not we have succeeded. If the situation worsens, we have to face the crisis,” Yediyurappa said, quoting Modi. 

Apparently, Modi sought details on the COVID-19 situation from 12-13 states where the situation is grave. “He did not take a report from Karnataka,” Yediyurappa said. “This morning, seven new cases were reported in the state, taking our tally to 214. Nationally, we were in the third place; we’re now 11th,” he said, hailing the efforts of officials involved in fighting the pandemic. 

The CM said it was “inevitable” to continue the lockdown for another 15 days. “But for citizens to get essential supplies, there’s no bar on them going by walk alone. Also, we will see to it that agricultural activities are not affected anywhere,” Yediyurappa said.

Bengaluru, Jan 30: Karnataka Chief Minister B S Yediyurappa, who reached the national capital on Thursday, said he will discuss the much-awaited Ministry expansion with the BJP high command.

"It's been long that I visited Delhi. I will meet the party national president J P Nadda and Home Minister Amit Shah and take their suggestions on the cabinet expansion," Yediyurappa told reporters.

The chief minister said he will also call on Finance Minister Nirmala Sitharaman and Petroleum Minister Dharmendra Pradhan and discuss about development issues related to Karnataka.

Yediyurappa has been anxiously waiting for the high command's nod to expand his ministry amid intense lobbying by the aspirants.

Opposition parties have been critical of the BJP and Yediyurappa over the delay in cabinet expansion, alleging that he was weak and that the administration had collapsed.

As the chief minister has already made it clear that 11 of the disqualified JDS-Congress MLAs who got re-elected in the bypolls on BJP tickets will be made ministers, lobbying has been on in the party for the remaining ministerial berths.

Currently, there are 18 Ministers, including the chief minister in the cabinet that has a sanctioned strength of 34. Sixteen berths are vacant.
