10 years after Mangaluru Air crash, SC awards Rs 7.64 cr comp to kin of one of the victims

Bengaluru, Apr 25: Former Karnataka Health minister and senior Congress leader Dr H C Mahadevappa on Saturday urged the state government to chalk out a comprehensive plan to conduct tests among the vulnerable sections in the society to impede the spread of the dreaded COVID-19 pandemic in the state.

Speaking to media persons, Dr Mahadevappa, felt that only restricting people to remain indoors will not suffice to tackle the spread of the contagious disease he said that "There needs to step up testing the people especially belonging to the vulnerable sections of the society".

Maintaining that the COVID-19 disease, which has progressed itself as a pandemic, across the globe, former Health Minister said that "there is also a need to fight the menace with multiple dimension, as it has potential to cause damage not only the social life of the people but also their livelihood".

Lucknow, Apr 29: Tablighi Jamaat members, who got cured of COVID-19, have been asked by their organisation to donate their plasma for treatment of other coronavirus-infected patients, a move that the outfit thinks will help it shed its “villain” tag.

"Maulana Saad, in an open letter on April 21 to all Jamaatis who have recovered from the coronavirus (infection), has appealed them to donate their plasma to help others. The message has reached all the members," Maulana Anees Ahmad Nadvi, the manager of Tablighi Jamaat’s Lucknow branch, told PTI PTI on Wednesday.

"As per the Health Department data, over 50 per cent of corona patients are Jamaatis. Among them those who have recovered are being contacted and all of them are ready to donate their plasma," claimed Nadvi.

"We have till now contacted 400 Jamaatis. In the entire country, those who have recovered are also giving their plasma. Markaz has given instructions that no one should be left from donating plasma," he said. "Jamaatis are not doing any favour to anyone by giving their plasma.

This is a humanitarian step. This is true that Jamaatis are being presented as villains after coronavirus spread, but Maulana Saad has asked us to forgive those doing this," he said. Tablighi Jamaat leader Maulana Saad Kandhalvi is on the run after an FIR was registered against him by the Delhi police for organising a religious gathering in March this year despite restrictions to combat the coronavirus spread.

With some plasma therapy trial results rekindling hopes of it being a likely cure for COVID-19, the Uttar Pradesh government too had begun contracting patients cured of it for plasma donation, but the move was suspended after the Union Health Ministry on Tuesday said the therapy was only at an experimental stage and there was no evidence yet to support that it can be used as treatment for COVID-19.

Uttar Pradesh Surveillance Officer, Dr Vikasendu Agarwal, said all those who have recovered from coronavirus, including Jamaatis, were being contacted for plasma donation, but the move has been suspended after the Centre’s statement on the issue.

Refusing to divulge the number of cured Jamaatis, he said "We were contacting them. They are not different from us. We were contacting all our patients and asking them that they could donate if they find it appropriate, as it would help other patients." "All of those contacted by us are ready for giving plasma," he said.

Chief Medical Officer, Lucknow, Dr Narendra Agarwal said all 28 Jamaatis, who were admitted in KGMU were contacted to donate their plasma and all of them agreed. "A proposal in this regard has been sent to the government.

After approval, their plasma will be taken," he said. With the plasma therapy gaining a lot of traction as a possible cure for coronavirus, the Union Health Ministry on Tuesday clarified that it is at an experimental stage and there is no evidence yet to support that it can be used as treatment for COVID-19. Till the effectiveness of this mode of treatment is scientifically proven, its application except for research and clinical trial is illegal, Joint Secretary in the Ministry of Health Lav Agarwal said.

Dr Vikasendu said after the Centre's clarification contacting people for plasma donation has been put on hold. A further step will be taken on decision of KGMU which is working on plasma therapy here, he added.

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
