Bengaluru, Jun 26: A 60-year-old woman, who tested positive for COVID-19 positive and was undergoing treatment, allegedly committed suicide by hanging herself in the restroom of KC General hospital last night.

According to the police, the 60-year-old female COVID-19 patient hung herself in the restroom of KC general hospital in Bengaluru. She was admitted to the hospital on June 18 along with her daughter-in-law and grandson.

"Around 2 am, she went to the washroom. When she did not return back, her daughter-in-law went to check where she found her hanging dead," confirmed Bengaluru police.

An investigation into the matter is underway, police said.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Feb 20: The poultry industry is facing losses amid rumours of the discovery of a chicken infected with coronavirus in Bengaluru.

DK Kantharaju, president, Karnataka Cooperative Poultry Federation said, "Karnataka is facing losses of Rs 60 to 65 crores. The consumption percentage has also decreased by 30-35 per cent".

Atiq, a meat seller, said, "Because of coronavirus people are scared. But I want to say that chicken is safe to consume here. All this fear is caused due to fake news on social media."

Another person Abdul Hafeez said, "Chicken and coronavirus are not related. People are scared because of what is being spread on social media. The business has definitely gone down due to fear of coronavirus."
