Kalaburagi, Mar 3: Former Karnataka Minister Priyank Kharge on Monday in a letter requested Karnataka Assembly Speaker Sri Vishveshvaraya Hegade Kageri that the restricted media coverage in Assembly Budget session was not the right thing and it will be danger of for healthy democracy.

The letter written by Mr. Kharge to the Karnataka Assembly speaker which available to the press said that the fourth pillar of democracy 'Media' ban from covering assembly proceedings was not a healthy move and requested to immediately withdraw the government order in this regards, he said.

Mangaluru, Jul 21: Private hospitals cannot send back COVID-19 patients for any reason, district in-charge minister Kota Srinivas Poojary said on Monday.

The Minister was addressing a meeting at the Father Muller Medical College here on the arrangements made for COVID-19 patients.

Dakshina Kannada district is quite advanced in the medical field. Hence, the government will not tolerate COVID-19 patients wandering from one hospital to another for treatment. Refusing to admit COVID-19 patients in hospitals is unacceptable, he warned.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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
