Hindutva leader in police net for Gauri murder; Mangaluru man involved: TV report

Mangaluru, Jul 2: A frontline covid-19 warrior who was working in the Wenlock Covid hospital in the city has been tested positive for the coronavirus. 

Sources said that he was a pathologist working in covid testing laboratory of the Wenlock Covid hospital.

A few days ago, a senior health official had tested positive for the covid-19.

Dakshina Kannada has so far recorded deaths of 18 covid-19 patients. A total of 14,137 samples have been tested, out of which 13,040 have turned out negative, and 833 positive, including 10 persons from other districts. 372 cases are currently active.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Jul 15: Toyota Kirloskar Motor (TKM) has announced temporary halt of production at its plant in Bidadi, which is on the outskirts of Bengaluru.

“Halting production will be from July 14 (second shift) to July 22 (first shift) and this is in accordance with the directives issued by the Government of Karnataka as well as to support the Govt. in their constant efforts to flatten the curve of the rising Covid-19 positive cases in Karnataka,” a statement from the company said.

Bengaluru Urban and Rural, and other districts are, are under lockdown from 8 pm on July 14 to 5 am on July 22.

“Since the onset of the pandemic, TKM has adopted a very proactive and multi-faceted approach to safeguard the physical as well as the mental well-being of all its stakeholders including customers, its employees, dealer and supplier partners,” the company said.

“The office staff at TKM’s corporate and regional offices, continue to work from home to help mitigate risks. In addition to the safety protocols that are being followed, TKM has provided safety kits containing essential items like sanitisers, 3 ply masks and handwashes to 5000 employees, their family members and their neighbourhoods.

“TKM understands the urgency of the situation. During these difficult times, TKM is taking obligatory actions to contain further spread and will continue to respond in accordance with guidance issued by the Government and its internal standards,” it added.
