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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Mar 24: The District Wenlock Hospital Superintendent Dr H R Rajeshwaridevi has filed a complaint with the police on Tuesday seeking action against those circulating fake videos of a man infected with COVID-19, at the hospital.

In the video, a man was seen struggling to breathe at a hospital. The message in the video says that the man was admitted at Wenlock Hospital.

Dr Rajeshwaridevi, who issued a clarification, stated that video clips which are being circulated on social media is not from Wenlock Hospital.

Moreover, Wenlock Hospital does not use blue colour beds.

Bengaluru, Jan 14: Days after the Reserve Bank of India (RBI) capped to Rs 35,000 the withdrawal limit of Sri Guru Raghavendra Co-operative Bank, BJP MP Tejasvi Surya on Monday reassured account holders and said Finance Minister Nirmala Sitharaman was personally monitoring the issue.

Taking to Twitter, Surya said, "I want to assure all depositors of Sri Guru Raghavendra Co-operative Bank to not panic. Hon'ble Finance Minister Nirmala Sitharaman is appraised of matter and is personally monitoring the issue. She has assured the government will protect interests of depositors. Grateful for her concern."

The Bengaluru South MP also attached a letter in his tweet where he had appraised Sitharaman of the situation.

"Finance Minister, after speaking with the RBI governor and other authorities concerned, assured Surya that the government will do everything in its capacity to protect the interests of the depositors and the long term interests of the bank," the letter read.

It said that Surya also reached out to Sitharaman "three times on January 13" after which she reassured him that the "depositors need not panic".

RBI had, on January 10, imposed certain restrictions on Sri Gururaghavendra Sahakara Bank Niyamitha.

"In particular, a sum not exceeding Rs 35,000 of the total balance in every savings bank or current account or any other deposit account may be allowed to be withdrawn subject to conditions stated in the above RBI directions," the notification said.

The regulatory body said that the bank will continue to undertake banking business with restrictions until its financial position improves.

"These directions shall remain in force for a period of six months from the close of business of January 10 and are subject to review," it said.

The bank has been restricted from granting or renewing any loans and advances, make any investment, incur any liability including borrowal of funds and acceptance of fresh deposits, disburse or agree to disburse any payment whether in discharge of its liabilities and obligations or otherwise, enter into any compromise or arrangement and sell, transfer or otherwise dispose of any of its properties or assets except.
