Stage set for Apr 18 LS poll in DK; 13 candidates including 7 independents remain in fray

Bengaluru, May 1: Karnataka has reported 11 new cases of coronavirus, taking the State's count to 576, informed the Health Department on Friday.

Out of the total COVID-19 cases found in the State, 235 people have been discharged and 22 people have died.

"11 new COVID-19 cases have been confirmed in Karnataka from April 30, 5 pm till noon today, taking the total number of cases to 576, which includes 22 deaths and 235 discharges," said the State government COVID-19 bulletin.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 26: Senior Congress leader Siddaramaiah said that Union Home Minister Amit Shah should issue strict orders to the police in Delhi to act in nation's interest and control the ongoing violence.

"Distressing scenes in Delhi!! #DelhiBurning as a result of ulterior motives of divisive forces within our Country. Police have completely failed in their responsibility. People have to remain calm and promote peace in the area for their own benefit," Siddaramaiah tweeted.

"Seven people dead and hundreds are injured, Amit Shah should issue strict orders to police to act in nation's interest and not in the interest of few people. As Gandhiji said, An eye for an eye makes the whole world blind. Peace and harmony should be our moto," he added.
Siddaramaiah further stated that the "triggering point of the #DelhiViolence seems to be the inciting speech of BJP leader Kapil Mishra."

"This actually qualifies for a sedition case as it was aimed at disturbing national peace and security. Police have to arrest him and bring normalcy in Delhi," he wrote.

Siddaramaiah has further asked Karnataka Chief Minister BS Yediyurappa to be careful "before situation goes out of hand."

"Delhi riots are in front of eyes. There will be tough situation here in state as well if those loose tongue leaders in BJP are not stopped in the state," he wrote.
As many as 18 people have lost their lives and around 190 are injured in the violence that has been raging in parts of North-East Delhi from Monday.
