Kannada is our mother, Tulu is father: Pejawar seer tells people of DK, Udupi

Bengaluru, May 10: Former Karnataka Chief Minister HD Kumaraswamy on Sunday accused the state government of not preparing proper guidelines to bring back people who are stranded near the Karnataka-Maharashtra border areas.

"No proper guidelines have been given to officials to bring back people who are stranded near the Karnataka-Maharashtra border. From the last 45 days, many of these people have not got any relief nor are there any proper directions or guidelines from the state government," alleged Kumaraswamy.

He also accused the state government of cheating the people of Karnataka.

"Karnataka government is cheating people the same way it cheated with the flood compensation. The state government had announced lakhs of rupees as compensation to those who lost houses in the flood last year. But nobody has got the records or details as to how many people got benefited from it," he added.
Fifty-three more COVID-19 cases were reported in Karnataka on Sunday, the state government said.

The total number of cases in the state is at 847, including 405 discharged and 31 deaths so far, the bulletin said.

Udupi, July 1: In a concerning development, another SSLC student in Udupi district has tested positive for covid-19.

With this the number of covid-19 patients among SSLC students in the coastal district rose to three. All of them are girls.

The fresh case has been reported from Byndoor. She has already written three papers.

She had reportedly developed some of the symptoms and hence her throat swabs were sent for testing on June 30. Today she received positive report, sources 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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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
