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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 18: Within days after Kambala racer Srinivasa Gowda emerged a national hero, another Kambala racer Nishant Shetty has grabbed headlines. 

Nishant Shetty from Bajagoli Jogibettu reportedly broke Gowda’s record at the Venoor Kambala on Sunday. Shetty recorded 143m in 13.68 seconds. If calculated for 100m he clocks it in 9.51 seconds. His speed is faster than Gowda who clocked 9.55 seconds.

According to Kambala organisers, with Shetty’s feat, four participants have joined the elite club of racers who have completed the 100 metres in less than ten seconds.

They are Iruvathur Anand (9.57 secs), Akkeri Suresh Shetty (9.57 secs), Srinivas Gowda (9.55 secs) and Nishant Shetty (9.51 secs). Anand and Suresh Shetty had participated in the same Venoor Kambala where Nishant emerged first.

Kambala is an annual race held in Karnataka where people sprint 143m through paddy fields with the buffaloes. During the race, the racers try to bring the buffaloes under control by holding their reins tight and beating them, making it amply clear that the animal plays an equally important role in achieving the timing. Traditionally, it is sponsored by local Tuluva landlords and households in the coastal districts of Dakshina Kannada and Udupi.

Bengaluru, Jun 4: Assuring support to reform the police department, Karnataka Chief Minister B S Yediyurappa on Thursday directed officials to strengthen Cyber Crime, Economic Offences & Narcotics (CEN) stations and forensic labs in the state.

The Chief Minister who held a review of the Home Department, lauded the work of police personnel during the COVID-19 crisis, and promised necessary help to reform the department.

Pointing at the changing scenario, the Chief Minister instructed officials to give priority to strengthen CEN stations, his office said in a release. Similarly, for quick detection of crimes, necessary action will be taken to strengthen forensic labs, he added. During the meeting it was also decided to continue more than 3,000 home guards, who were in the fear of losing jobs, and to deploy them to various departments.

Yediyurappa directed officials to take necessary steps to make home guard services available to private organisations also. Officials informed the Chief Minister that all necessary COVID-19 related precautions have been taken at prisons and no case has been reported so far at jails. They said as per Supreme Court directions, 5,005 people were released on bail and parole, and congestion of prisoners at prisons has been reduced from 110 per cent to 95 per cent.

Yediyurappa also asked the officials to submit a proposal based on facts towards development of basic amenities that comes under the Home Department.
