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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 7: Deputy Chief Minister Dr. Ashwatha Narayana said journalists are facing a challenging task of functioning with credibility while also upholding their professional ethics in this age of globalization where monetary aspects have gained great significance.

Bengaluru, Apr 18: Karnataka Health Minister B Sriramulu drew flak from his own party the BJP as well as the Congress for allegedly letting hundreds of people throng the Rupangudi Road in Ballari to collect food packets from him.

Visuals showed that the people came in hordes and fell on each other to collect the packets Sriramulu was distributing to the poor and needy as relief measure in the wake of lockdown.

The videos showed the minister standing with his team by the roadside and spreading out tables all along to distribute the food kit to the poor people.

Those in the queue had elderly people too.

A majority of people who rushed to grab the food packets did not bother to protect themselves with a mask.

"Whoever has done he has committed a blunder whether it is Sriramulu in Ballari or Anand Singh in Hospet.

All these elected representatives want to show that they are serviing the people in their constitutuency," said Karnataka BJP spokesperson Go Madhusudana.

Flaying the leaders of all political parties for defying norms, Madhusudana sad this has become fashionable for the leaders to perform 'cheap shows'.

He advised Sriramulu that it should have been done with door-to-door delivery of food packets instead of arranging it at the public place.

Congress spokesperson K E Radhakrishna said a case should be registered for defying regulations.

"I am all appreciation for Prime Minister Narendra Modi and Karnataka chief minister B S Yediyurappa who were the first to wake up and do something good for the people.

Now I feel sorry for them.

I wonder why they cannot control their own partymen.

People should file FIR against him (Sriramulu)," Congress spokesperson Prof K E Radhakrishna said

Slamming the alleged VVIP culture in the country, Radhakrishna said when the nation is facing a crisis, lavish marriages and grand birthday parties were organised. In the midst of all this health minister organises a food distribution mela, he added.

Attempts to reach the minister went in vain.

However, speaking to reporters at Ballari, Sriramulu admitted that the cases suddenly shot up in the state because of disregard to social distancing.

"People's support to lockdown is essential.

People have to maintain social distancing, without which we cannot control it," the minister said.
