Udupi: Sadhwi Balika Saraswati invited for Hindu Samajotsav

Bengaluru, Mar 8: The Indian Council of Medical Research (ICMR) has identified three more locations to open Viral Research Diagnostic Laboratories (VRDL) including in Mysuru, Hassan, and Shivamogga in Karnataka.

According to a statement issued here on Sunday, these laboratories will start functioning shortly in Mysuru Medical College and Research Institute, Hassan Institute of Medical Sciences, and Shivamogga Institute of Medical Sciences. Besides, the ICMR has also identified sample collection centres in Vijayanagar Institute of Medical Science in Ballari and Kalaburgi Institute of Medical Sciences.

B G Prakash, State Joint Director (Communicable Diseases), said that the new Laboratories will help to ease the load on the two designated laboratories in Bengaluru. Currently, the virology laboratory in Bangalore Medical College and Research Institute and the NIV branch in Rajiv Gandhi Institute of Chest Diseases are doing COVID-19 tests in Karnataka.

Bengaluru, Feb 4: Congress MLA UT Khader on Tuesday alleged that B.S. Yediyurappa-led government has stopped providing free food to poor families under 'Anna Bhagya' scheme from last two months which was started by the Congress in the state.

"Former Chief Minister Siddaramaiah had started a scheme 'Anna Bhagya' under which free rice and wheat to 494 education institutions, NGOs, and old age homes were provided and the present government has stopped providing benefits to the poor people," said the MLA.

Alleging that the present government has stopped with the scheme Khadar said, "From last two months the government has stopped providing free food to the institutes and NGOs."

Khadar further demanded to restart the scheme to help the poor students.

"They should restart the scheme which supports poor students and old age houses, or congress will protest if the scheme is not restarted."

Last year in August, Karnataka Chief Minister B.S. Yediyurappa had said that his government has no plans to stop any "pro-people schemes" including Anna Bhagya.

"Our government has no plans to scrap any of the pro-people schemes. Our Government is a pro-people Government. I have already signed the file to release grants to continue the "Anna Bhagya scheme" the twitter handle of Karnataka Chief Minister's Office had quoted him as saying.

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
