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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Dubai: The father of a 16-year old girl who came on a visit visa to the UAE to visit him is desperate for help as she has been hospitalised, even as he has been rendered jobless.

On February 6, Amber D’Couto flew into Dubai from Mangaluru, India, along with her older sister, Alison, 19. The girls wanted to visit their dad Vivian D’Couto who was working in an automobile company at Jebel Ali.

The father was overjoyed to meet his girls until things took an ugly turn.

Two months into her stay, Amber fell seriously ill, even as D’Couto was served a termination letter by his company.

D’Couto said his daughter, a Grade 10 student, was perfectly healthly but suddenly developed high fever and began vomiting. She was rushed to a private hospital in Qusais which could not accommodate her because of the ongoing COVID-19 situation.

On April 30, she was admitted to another private hospital in the same area. After testing negative for COVID-19 thrice, she was diagnosed with acute pancreatis and Rheumatoid fever.

While the girl remains in hospital, the bill has spiralled to over Dh50,000, D’Couto said, adding that without a job now, he had no means to pay the huge amount.

“Amber is a very sweet child and a very bright student. She was living a very healthy life prior to coming to Dubai. But she is so ill now and under round-the-clock vigil in the ICU. The treatment for her condition is very specific and costly.”

A worried man, he said: “My daughter was on a visit visa and she had no insurance. We appeal to compassionate people to help us out in this difficult hour. Due to the current situation, I have lost my job and I am unable to pay for her medical expenses. Her condition has not stabilised yet and I am taking each day as it comes. I trust the doctors to help her recover, and we hope to be repatriated to India at the earliest so she can get further medical care.”

Bengaluru, Jul 18: Vendors in Bengaluru are finding it hard to earn a livelihood as the state government has allowed the sale of products only for a few hours each day. The lockdown imposed by the Karnataka government on July 14 will continue till July 22.

Speaking to ANI, Vanajakshi, a local vendor said, "We took loans from banks and small financiers to run our business. But we are finding it tough to pay back as our livelihoods have been hit."
"Because of the lockdown, no one comes to buy and markets remain vacant. There was a time when the Gandhi Nagar market was filled with customers, but now it looks like a vacant playground," she added.

Mythri, an advocate, said, "Look at the conditions of vendors. It's precarious. They do not have any business at all. Even now they have been allowed to sell products till 12 noon, which is not sufficient. It's time for the government to step in and provide assistance. If the Central government can reduce corporate taxes, why can't it help them? At least it will help them pass off these difficult times. "

"They are earning through daily wages. The government imposed lockdown suddenly. Where will they go? The city market in Bengaluru is famous. At least 8,000 people come from slum areas. People here are poor. The lockdown was done suddenly and led to problems for these people," said Congress MLA Zamil Ahmed Khan.

Referring to a recent meeting with the chief minister BS Yediyurappa, he said, "During the meeting called by the CM, I suggested that food kits must be arranged for vendors. The CM said the government is providing rice and wheat but that's not enough."
