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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Jan 22: Defence Minister Rajnath Singh on Wednesday said Indian values consider all religions equal, and that is why the country is secular and never became a theocratic state like Pakistan.

Speaking at the NCC Republic Day Camp in Delhi, Singh said: "We (India) said we would not discriminate among religions. Why did we do that? Our neighbouring country has declared that their state has a religion. They have declared themselves a theocratic state. We didn't declare so."

"Even America is a theocratic country. India is not a theocratic country. Why? Because our saints and seers did not just consider the people living within our borders as part of the family, but called everyone living in the world as one family," the minister said.

Singh underlined that India had never declared its religion would be Hindu, Sikh or Buddhist and people of all religions could live here.

"They gave the slogan of 'Vasudev Kutumbakam' -- the whole world is one family. This message has gone to the whole world from here only," he added.

Mumbai, June 7: As the Maharashtra government has given green signal for outdoor physical activities under 'Mission Begin Again' despite amidst growing cases of covid-19,  thousands of Mumbaikars flocked to Marine Drive for 'morning walks' on Sunday.

People were seen wearing masks as a precaution from the novel coronavirus pandemic, however, from the viral photo, it seems that no social distancing norms were followed what so ever.

"Better call it marne waalon ka drive," said a Twitter user. "Still people have no sense of responsibility," said another Twitter user.

After nearly 80 days of lockdown, Mumbai and other parts of Maharashtra revved back to life on Friday. 

Most markets, market areas, commercial and trading areas - barring malls or market complexes - reopened for business even as Chief Minister Uddhav Thackeray reiterated that "people should tread cautiously while beginning a 'new life' from today".

Meanwhile, of the total 82,968 cases in Maharashtra, Mumbai now accounts for 47,354 cases and 1,577 deaths.

On Saturday, Maharashtra reported 120 deaths, including 58 in Mumbai, due to COVID-19, taking the overall number of fatalities to 2,969, state Health department said.

The recovery rate in the state stands at 45.06 per cent and the fatality rate at 3.57 per cent, an official statement said.
