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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, Jan 24: Aditya Rao, who was arrested for planting Improvised explosive device (IED) at Mangaluru airport on January 20, was brought to the airport on Friday for recreation of the crime scene as part of the investigation process.

Yesterday, one more case was registered against Rao in connection with a hoax call to the terminal manager of the airport on January 20, police said.

"One more case has been registered against Aditya Rao at Bajpe Police station for a hoax call to the terminal manager of Mangaluru International Airport on January 20," said PS Harsha, Mangalore Commissioner of Police on Thursday.

Earlier, Harsha informed that Rao, who surrendered before the Bengaluru Police, is now in the custody of Mangaluru Police.

"Our investigation team arrested Aditya Rao in Bengaluru in connection with the planting of an explosive device at Mangaluru airport. We produced the accused before Bengaluru's first JMFC court and the court issued a transit warrant," Harsha said.

"We have brought him to Mangaluru from Bengaluru and now the accused is in our custody. Our investigation team will interrogate him. We will investigate all aspects. He will be produced before Mangaluru 6th JMFC Court," he added.

Rao hails from Udupi and has engineering and MBA degrees.

According to the police, the IED was recovered from a bag at the Mangaluru airport. It was later defused in an open field by the personnel of the bomb disposal squad.

Bengaluru, May 12: In a scathing attack on the ruling BJP in Karnataka and warning the Chief Minister B S Yediyurappa government against any move to amend the Labour laws and APMC through an ordinance, former chief minister and JDS leader H D Kumaraswamy on Tuesday asked Mr Yediyurappa to work in the interest of the people and not to budge under any pressure from the Centre or to please party bosses.

Speaking to media here on Tuesday he questioned the urgency to bring forward such ordinances on important subjects and asked the government to have a public debate on it and also discuss it in the assembly.

“I'm warning the government… I have been watching everything silently till now, I have not caused any embarrassment to the government. I want to tell the government, don’t push us to do it,” Kumaraswamy said
