‘Independent’ Jignesh Mevani gives a blow to BJP in Gujarat; wins from Vadgam

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 15: As the central government has not allowed reopening of gyms in the country amid COVID-19 pandemic, many gymnasiums in Bengaluru are on the verge of closing or sale.

Rakshith Gowda, a gym owner and secretary of gym owners association told ANI that they are not even able to pay rent of the premises which is Rs 60,000 to 1 lakh per month.

"The condition of the owners of the gym have worsened. We have to pay a minimum of Rs 60,000 - 100,000 rent of the building and for past 4 months we couldn't pay the rent, salary to trainers and cleaners, EMI," Gowda said.

"I urge the government to take necessary steps to bring up the gym sector as they have allowed opening up of shops, temples, malls. We urge the government to take proper steps in the interest of gyms," added Gowda.

Mahesh, a gymer said that he had to participate in a competition and due to lockdown he could not work on his bodybuilding.

"I was building my body for one year and due to lockdown I couldn't do the workout, I had to take part in a competition, now I need at least another one year to build my body back," Mahesh said.

Prasad, international bodybuilder said, "Most of the bodybuilders and gym owners are running gyms by taking loans, they are not in the situation to pay their loan EMIs."

"It's very important for us to reopen gyms and run them with all precautions and guidelines but the government is not allowing us to pay our loans and many gym owners and trainers are facing a tough time to earn living. We have requested Deputy Chief Minister Govind Karjol and cabinet ministers to allow us to open, but the government hasn't taken the decision in the interest of gyms which is creating more problems for us," Prasad said.

Shivamogga, May 10: Karnataka Minister KS Eshwarappa on Sunday informed that eight people who returned to the state from Gujarat have tested positive for COVID-19 in Shivamogga district.

Shivamogga district is under the green zone category.

"Eight people who have returned from Ahmedabad, Gujarat have tested positive for COVID-19 in Shivamogga," said Eshwarappa.

Last week, the district administration had asked shopkeepers to open their shops on alternate days in order to avoid crowding.

According to the Ministry of Health and Family Welfare, the state has so far 794 confirmed COVID-19 cases which include 386 cured or discharged cases and 30 deaths.
