‘Restless’ minister U T Khader hospitalized in Bengaluru

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jul 12: Karnataka on Sunday registered 71 COVID-19 deaths, its highest single day count, and 2,627 fresh cases, pushing the tally of infections in the state to 38,843, the health department said.

Among the districts, where new cases were reported, Bengaluru urban accounted for 1,525 cases, followed by Dakshina Kannada with 196, Dharwad 129, Yadagiri 120, and 19 in Bengaluru Rural.

Since the outbreak of the pandemic, 8.39 lakh samples have been tested including 20,050 on Sunday alone, of which 7.80 lakh tested negative.

Other than Bengaluru, five fatalities were reported in Dakshina Kannada, three each in Mysuru, Hassan, Davangere and Belagavi, two each in Haveri and Bagalkote and one each in Dharwad, Koppal, Tumakuru, Vijayapura and Chamarajanagar.

While majority of those who died of coronavirus suffered from Severe Acute Respiratory Illness and Influenza Like Illness, significantly 21 victims did not have any pre-medical conditions while eight were the asymptomatic patients with pre-medical conditions.

Bengaluru, Jan 8: Accusing the BJP of running a "fake news factory" at full potential, former chief minister Siddaramaiah on Tuesday said according to reports only Rs 669 crore of additional flood relief funds are being released by the Centre for the state as opposed to the ruling party's claim of Rs 1,869.85 crore.

Reacting to his attack, the State BJP unit, without clarifying on the actuals of the amount being released, said it believed in speaking the truth and not spreading lies.

Siddaramaiah, leader of the opposition in the state assembly, tweeted: "Reports from State govt officials tells that only Rs 669 crore of addl funds (sic) are released in 2nd instalment as opposed to the claim of Rs 1870 Cr by @BJP4Karnataka leaders. At a time when manufacturing industries are closing, BJP's fake news factory is running at full potential!!"

Calling BJP leaders "devotees of the God of lies," he said in another tweet that Prime Minister Narendra Modi released an additional Rs 669.85 crore moved by Chief Minister B S Yeddyurappa's plea, taking the total amount to Rs 1,869.85 crore. He said it was funny that they were attempting to depict the total relief amount as 1200+1869.85 equalling to Rs 3,069.85 crore.

Siddaramiahs tweet was in response to Karnataka BJPs tweet last night claiming that the High-Level Committee (HLC) Chaired by Union Home Minister Amit Shah has approved the release of Rs 1869.85 crore as central assistance to the state towards flood relief. This was in addition to Rs 1200 crore already released by the Centre in October 2019, the BJP unit had said.

On Monday, the HLC had approved additional central assistance to seven states affected by floods last year, from National Disaster Response Fund (NDRF), including Karnataka.

While a PIB release states that Rs 1869.85 crore was approved for Karnataka, according to sources in the state government the figure was inclusive of Rs 1,200 crore released in October. Earlier in the day, Chief Minister B S Yediyurappa while expressing confidence that more funds will be released in later stages, maintained that Rs 1869 crore has been released in addition to Rs 1,200 crore earlier, and thanked Prime Minister Narendra Modi.

"...funds will never be enough, they (central government) will release in stages, they have released such big amount- earlier Rs 1200 crore, now again Rs 1869 crore- I thank Prime Minister Narendra Modi for it," he told reporters here.

Revenue Minister R Ashoka said the state government will press for more funds in the days to come, and the state government will fulfil promises made to those hit by floods.

Karnataka faced two spells of unprecedented rains and floods last year, resulting in widespread damage to life and property, following which the state government had submitted a report to the centre claiming loss was to the tune of about Rs 38,000 crore.

Reacting to Siddaramaiah's attack of "fake news factory" against it, the state BJP tweeted "Ayyo @siddaramaiah Avare, We surrender to You as we are incapable of running Fake News Factory like You or @INCIndia.

We believe in speaking the Truth like Gandhiji, not spreading lies like Goebbels. Kannadigas still remember the "Lies Bhagya (a scheme)" you gave them as CM from 2013-18."
