Karnataka launches job portal connecting employers and job seekers

Bengaluru, Jun 8: Normal life is slowly returning to normal across Karnataka with the state government further easing the restrictions by throwing open places of worship, hotels, malls for the public.

Despite these places being opened after a gap of more than two months, the places wore a deserted look as the people are and cautious and not ready to take of risk of venturing out amid the ongoing Corona threat.

"Business is not as heavy as expected though it was allowed after a gap of almost three months. You can see for yourself the crowd, it is not what it should have been in a commercial area like this prior to the imposition of lockdown. However, hope it will improve", a Cloth merchant B Ramesh told UNI when asked for his reaction.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 13: Karnataka Minister CT Ravi has tested positive for COVID-19. However, his wife and staff members have tested negative.

"Yesterday, I along with my wife Pallavi and my staff members underwent COVID-19 test. Fortunately, my wife Pallavi and all my staff members are tested negative. Third umpire's result for me has confirmed that I'm COVID Positive. However, I'm feeling absolutely fine," Ravi tweeted.

"For now, I'll continue to work from here and undergo treatment. Very soon, I'll get cured and come back to work with you all," he added.
So far, Karnataka has reported 36,216 COVID-19 cases, according to the Union Ministry of Health and Family Welfare.
