In 3 years 9 RSS, BJP activists murdered in Karnataka: Home Minister

Bengaluru, Mar 12: The Karnataka government on Wednesday clarified that no coronavirus "emergency" has been declared in the state and that all the schools and offices will remain open.

Earlier, there were fake reports that Karnataka has declared "coronavirus as an epidemic" in the state.

In a statement, Karnataka health commissioner Pankaj Kumar Pandey refuted the reports doing rounds on social media which said Karnataka had declared COVID-19 as a "state epidemic".

Refuting the rumours, he added that all the schools, offices and other institutions will continue to function normally in the state.

The Karnataka government earlier today issued temporary regulation which asked all government and private hospitals to have flu corners for screening of suspected cases of COVID-19.

According to the regulation, no person/institution shall use print or electronic media to spread mis-information on COVID-19 without prior permission of the department of health & family welfare. If a person is found indulging in any such activity, they will be punished, it said.

The Karnataka government also started a campaign called 'Namaste over Handshake' that encourages people to greet in the traditional Indian style, to tackle the spread of the virus.

The state has reported four positive cases of coronavirus so far.

India, so far, has 60 confirmed cases of coronavirus, including 16 Italians tourists.

Bengaluru, Jun 19: Congress leaders BK Hariprasad and Naseer Ahmed filed their nominations as party candidates for Legislative Council elections in Bengaluru and KPCC chief DK Shivakumar said that the two leaders have been given ticket to strengthen the party with their guidance.

"The Legislative Council means the Upper House and the Elders House. We have unanimously agreed to select and send these two senior leaders to discuss the party organization and various issues of the state in Legislative Council. There were plenty of aspirants to enter the Upper House. But it is decided to elect these two leaders and they will contest the election," Shivakumar said.

"We need seniority to guide us... That's the reason we are selecting these leaders... The high command has given these senior leaders the opportunity to discuss with all our leaders about strengthening the party," he added.

The elections are scheduled to be held on June 29.

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
