RSS chief pays tribute to Gauri Lankesh, Dharam Singh

Mangaluru, Jul 19: Five physicians of KVG Medical College in Sullia, Dakshina Kannada were booked for violating their home quarantine guidelines.

The district administration learnt about their quarantine violations after tracking their GPS locations through the app on Sunday.

The five medics were ordered 14 days home quarantine after the College staff tested positive for COVID-19. 

However, all the five physicians visited many places in the town violating quarantine norms, and hence the police booked cases against them.

Kota, Jan 4: Following the death of an infant in the morning, the death toll in JK Lon Hospital here has risen to 107, officials said on Saturday.

A three-member state government committee of doctors, who was sent to investigate the matter on December 23 and 24, found that Kota's JK Lone Hospital is short of beds and it requires improvement.

However, the committee gave a clean chit to the doctors for any lapses over the recent death of infants admitted there.

A Central government team reached the hospital on Saturday to take stock of the situation.

As per the government report, at least 91 infants lost their lives at the government hospital in December last year.

Meanwhile, the National Human Rights Commission (NHRC) has issued a notice to Chief Secretary of Rajasthan to submit a detailed report within 4 weeks about the steps being taken to address the issue.

The Commission also asked the Chief Secretary to ensure that such deaths of the children do not recur in future due to lack of infrastructure and health facilities at the hospitals.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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