Amid security concerns govt imposes ban on entry into Bababudangiri shrine

Mangaluru, Apr 21: An elderly woman from Bantwal taluk in Dakshina Kannada district has been diagnosed with covid-19, a deadly disease caused by coronavirus.

The state health and family welfare department, in its bulletin released on Tuesday morning, confirmed  that 67-year old woman suffering from covid-19.

The woman is said to be a neighbour of the woman from who died last Friday after being infected with coronavirus.

It is suspected that the virus reached elderly woman's body as she was in touch with the deceased.

The woman was admitted to Covid - 19 Hospital, Mangaluru, on the April 18 after she developed breathing problem. It is learnt that she is responding to the treatment

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Jun 4: Belur Mutt, the global headquarters of Ramakrishna Mutt and Ramakrishna Mission, has decided to throw open its gates to the devotees from June 15 after putting in place all safety measures required to contain the spread of COVID-19.

The gates of the sprawling premises of the mutt set up by Swami Vivekananada at Belur near here was closed since the lockdown was announced in March by the Centre. The Mutt has devotees from across the globe.

The secretary of Belur Mutt Ramakrishna Mutt and Ramakrishna Mission, Swami Suvirananda said in a statement that as the easing down of lockdown measures announced by the Centre and the state did not indicate the threat caused by COVID-19 pandemic is over, the authorities thought it prudent to put in place all the measures required before opening the gates of the Mutt and all RKM centres in the country for the scores of devotees.

The statement was issued on June 1, the day religious places of worship were thrown open by the West Bengal government.

"We had to think about both aspects - the issue of public health and also the wish of our devotees for having a darshan of the shrines of Swami Vivekananda, Sri Sarada Maa and Ramamrishna Paramahansa. But we believe spirituality and sceintific temparament must go hand in hand," he told reporters on Thursday.

"Therefore it is imperative for us to consult experts and put in place adequate arrangement and infrastructure" before opening the (Belur Mutt) gates," he said.

The senior monk said the timing of the opening and closure of the shrine and all other details conforming the health protocol and guidelines will be announced before opening date.

The Mutt complex had become totally out of bound for visitors from March 24 when the lockdown was clamped. There was restricted entry to it since May 16.
