Harish Poojary murder: Another Bajrang Dal activist nabbed from Gujarat

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

A 32-year-old Dalit man was allegedly stripped and assaulted by a group of 13 youth in Karnataka's Vijayapura for reportedly touching a motorbike of an upper caste owner, police said on Monday.

"On a complaint by the Dalit victim (Kashinath Talwar), we have booked the 13 accused and investigating the incident, which occurred at Minajgi village near Talikoti on July 18," Vijayapura district Superintendent of Police Anupam Agarwal told reporters here.

"Though Talwar claimed that he touched the bike by mistake and pleaded for mercy, he said the accused severely thrashed him with sticks and footwear and took off his pants while he lay on the road haplessly," Agarwal said, citing from the victim's 2-page complaint in Kannada.

A video clip of the assault went viral on the social media and triggered outrage in the district against the upper caste accused, as the intervention by the victim's parents did not stop them from carrying the assault. Vijayapura is 524km northwest of Bengaluru.

Talwar's father Yankappa also alleged that he, his wife and their daughter were also attacked by the accused when they tried to rescue him from being brutally assaulted.

In a related development, two-three women in the village also filed a complaint with the police against Talwar for allegedly eve-teasing and 'flashing' before them.

"We have summoned Talwar to inquire about his conduct as the women alleged that he teased them, touched them inappropriately and exposed his private parts while they were washing clothes outside their houses," Agarwal said.
