RSS, other outfits misusing temples for illegal activities: Kerala Minister

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Kalaburagi, Apr 17: Hundreds of people participated in the Siddhalingeswara temple chariot festival in Chitapur village on Thursday, violating the lockdown orders.

"Today at 6.30 am, around 100-150 people had come near Siddalingeshwara temple for about 20 mintues and took part in chariot pulling procession," Superintendent of Police Lada Martin said.

A case has been registered against 20 people and further investigation is going to ascertain more details related to the religious gathering.
Meanwhile, a sub-inspector has been suspended.

Thirty-six cases of coronavirus were reported in Karnataka on Thursday, taking the state's tally to 315.

Bengaluru, Jun 18: Karnataka Public Service Commission (KPSC) was reprimanded for withholding information, sought by a candidate regarding an examination held in 2005 for Gazeted Probationary posts, by the State Information Commissioner here on Thursday.

According to official sources, the State Information Commissioner NP Ramesh, while disposing off a petition by the candidate, who had written an examination conducted by the KPSC for the gazeted probationary posts held in 2005, had directed to provide the information sought by the candidate, free of costs within ten days.

The State Information Commissioner in his order had termed the conduct of the KPSC as against the spirit of transparency among the public authorities.
