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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 14: In a fresh case of vigilante attack, a cattle trader was tied to a buffalo-laden vehicle and thrashed by the miscreants belonging to Bajrang Dal in the city today. 

The victim has been identified as Mohammad Haneef Guddemane (34), a resident of Jokatte village on the outskirts of the city. 

The attack took place in the early morning near Infosys office at Urva, when Haneef was transporting his four buffalos to Kudroli slaughter house. 

The miscreants continued to thrash him until the local police reached spot. Based on the complaint of ‘illegal cattle transportation’ by the Bajrang Dal, the police took the victim to custody and also seized the buffalos. 

The police also took the victim to hospital and subjected him to covid test before producing him before a local judge.

While the Bajrang Dal members lodged complaint of illegal transpiration against the victim, the victim showed all the records of the cattle and lodged a counter complaint against the attackers.

It is learnt that Haneef had purchased 10 cattle from Haveri district and sold six among them. He was transporting remaining four buffalos to Kudroli slaughter house.

Lucknow, Jul 20: Dr Azizuddin Sheikh, who was fighting COVID-19 as a front line worker, passed away after contracting coronavirus in Uttar Pradesh. He is survived by a wife and three small children. 

40-year-old Dr Azizuddin, who hailed from Rajasthan, was serving as a paediatrician at Avanti Bai Hospital and Duffein Hospital, Lucknow for past few years. He had also worked in the Middle Eastern countries. 

When a large number of doctors preferred to stay home following the covid-19 outbreak, Dr Azizudin was working 16 to 17 hours battling the pandemic. 

According to sources, he tested positive for the covid-19 last month. “After the reports came positive, he had to call the concerned authorities many times to take him to the hospital,” recalled his family members.

He was first admitted to Lok Bandhu Hospital and was later shifted to KGMU after his condition deteriorated. Later he was taken to SGPGIMS.
 
“Despite following all the guidelines and taking every precaution while treating coronavirus patients, he tested positive for the covid-19. It’s a shock for all of us,” he said.

He used to console his family members and instill confidence among them, said one of his relatives. 

A local newspaper quoted his friends as saying that he was very dedicated in serving people that he used to take minimal possible fees from his patients. When the family asked him to increase consultation fees his reply would be, “They are poor people, how will they afford”?

After his death, one of his patients Alok Singh wrote about an incident. “When I asked doctor Sahib why he charges so less, his answer was I have to answer Allah. The truth that he has left us will always be the reason for our grief.”
