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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Udupi, Feb 16: Nine people were killed after a private bus collided with a large roadside boulder in Udupi district in Karnataka on Saturday, the police said. The accident took place on Saturday evening, at around 5.45 pm, on the Mulnur Ghat at Abbas Kattingeri in Mala village, while the bus was on its way to Mangaluru from Sringeri, reported the news channel.

The bus, which was reportedly carrying around 35 passengers, was trying to manoeuvre a turn while travelling on a ghat road when the driver allegedly lost control of the vehicle. The vehicle hit a massive boulder and the impact caused seven people to die on the spot. Two others passed away while they were on the way to the hospital.

The deceased passengers have been identified as Radha Ravi, Yogendra, Preetham Gowda, Basavaraju, Angana, Sharul and Ranjitha. The cleaner of the bus was also killed in the accident.

According to reports, the passengers in the bus were mostly in their early 20s and were employees of Vital Records Private Limited near JCK Industrial Park. Century Vital Records is a data security company which works in the Hebbal Industrial Mysuru. The group was visiting Udupi, Hornadu and Kudremukh.

While some of the injured persons were rushed to Manipal hospital, others were taken to the Karkala city government hospital, police said.

The police have said that rash and negligent driving by the driver is likely to have caused the accident. A case has been registered at the Karkala Rural Police Station, the police said.

Last month, three persons were killed and four others were injured after a fatal collision between a van and a bus near Bengaluru. Both the vehicles caught fire after the impact, but while passengers of the bus, travelling from Bengaluru to Shivamogga, managed to escape, the three passengers who were trapped in the van could not escape and were charred to death.

Bengaluru, Jan 19: Two college students have been arrested for allegedly spiking their female friend's drink and sexually assaulting her in Bengaluru.

The 19-year-old victim filed a complaint against the two accused, following which they were nabbed. In her complaint, the victim said that the two friends persuaded her to accompany them in a party where one of them allegedly spiked her drink.

Feeling unwell, she wanted to return to her PG, but the two managed to convince her to stay back at their place, where they allegedly sexually assaulted her.

"After some time one of my friends gave me something to drink and I vomited. I felt uneasy and decided to return to my PG. However, he forced me to go to his house stating that I was not in a condition to go to my PG. He convinced me saying that I can go home in the morning. I did not suspect any foul-play as he was a friend," the victim was quoted as saying by the publication.
