All of a sudden, NIA discovers Purohit's secret letter' against right-wing terror

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 28: The patience and presence of mind exhibited by the family members of youth covid-19 victim thwarted the attempt by a few miscreants to create communal disharmony in the coastal city today.

A 31-year-old youth from Idya in Surathkal, who was under treatment for covid-19 at designated Wenlock Hospital in the city, passed away last night. 

Even though there is a Muslim graveyard under the jurisdiction of Idya mosque, it was waterlogged due to heavy rains. 

Hence, the Idya mosque management had obtained permission from Mangaluru’s Bolar mosque management to bury the mortal remains of the youth in Bolar graveyard. 

All necessary arrangements were made at the Bolar graveyard for the burial this morning. Meanwhile, a few residents of Bolar belonging to another community staged a protest against bringing covid-19 victim’s mortal remains to Bolar.

Mohammad Husain, general secretary of Bolar mosque, said that the family members of the departed youth exhibited their presence of mind and urged the Muslims of Bolar to preserve communal harmony.

“The Bolar mosque committee had given green signal for the burial and all arrangements were made. Meanwhile, a few people staged protest and warned us against burying the covid-19 victim’s body. When the aggrieved family members came to know this, they immediately cancelled the plan,” he said. 

“The aggrieved family requested us to uphold communal amity and co-existence. They decided to bury the body in Idya itself. Then the protesters also returned,” he said.

Burial in Bolar after DC’s intervention

When the mortal remains were being taken towards Surathkal in the ambulance, the Deputy Commissioner of Dakshina Kannada ordered the authorities concerned to take a U-turn and bring back mortal remains to Bolar.  

The DC said it was wrong to take the mortal remains to another place after making all necessary armaments in Bolar graveyard. In order to pacify the porters it was decided to dig another grave on the other side of the graveyard, sources said.

Mangaluru, Mar 29: The state government has lifted the restrictions on the movement of chicken and eggs, thus ensuring the availability of protein-based nutrition to consumers.

Due to the 21-day lockdown in the State, police and other regulatory authorities were not allowing movement of poultry products, which not only had affected the entire poultry sector but also the consumers. The Karnataka Poultry Farmers and Breeders Association (KPFBA) had made a representation to the government to lift the restrictions.

The Secretary of Animal Husbandry and Fisheries, A B Ibrahim in a circular dated March 27, 2020 night , said that the minimal husbandry sector came under essential services and is given exemption during the lockdown period. He cited the letter which provides for the exemption, issued by the Government of India Home Secretary and the Union Joint Secretary of Animal Husbandry and Dairying.
