Gangster-turned social worker Muthappa Rai gets CCB notice over dangerous ‘Ayudha’ Puja

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, May 16: Former Karnataka Minister Dr Sharanprakash Patil, who was booked for violating COVID-19 imposed lockdown guidelines said on Friday that it was "politically motivated".

"It's politically motivated, the officer who filed the case was forced by MLA or some other people. As elected representatives, we're going in the constituencies, listening to people as they're apprehensive about the return of migrants. We had not conducted any meeting. Wherever we have gone we have followed social distancing," Patil said.

Patil said, "When I had gone there people came to discuss about a local problem and I was talking to an official concerned. In the meantime, some officer gave a complaint that we have violated the lockdown or something."

"They are trying to curb the voice of opposition because there are a lot of lacunae. We hear complaints about quarantine centres that there is no proper facility for food, or stay, or bathrooms," the Congress leader said.

The FIR was registered on Thursday against 23 persons, including the former MLA and 21 local Congress leaders, under Section 188 (disobedience to order duly promulgated by a public servant) of the Indian Penal Code (IPC).

Congress leader Patil and his followers had conducted a meeting at a convention hall in Sulpeth town on May 13, following which sectoral magistrate Muneer Ahmed lodged a complaint.
