Will launch 'new mission' after cabinet formation in Karnataka: Vijayvargiya

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bellary, Jan 4: A BJP MLA has apparently threatened 'minority' Muslims against participating in anti-CAA protests, saying that opposing the new Citizenship Act will not be good for them and they will have to face serious repercussions.

"It's just a caution for those who are protesting against the CAA (Citizenship Amendment Act). We are 80 per cent and you (Muslims) are 18 per cent. Imagine what will happen if we take charge," MLA Somashekar Reddy told a gathering here on Friday.

"Beware of the majority when you live in this country. This is our country. If you want to live here, you will have to, like the Australian Prime Minister said, follow the country's traditions," he added.

He said: "So, I warn you that CAA and NRC are made by Modi and Amith Shah. If you will go against these acts, it won't be good."

Continuing to spew venom, the MLA further said, "If you wish, you can go to Pakistan. We don't have any issues. Intentionally, we would not send you."

He said that the community should live in harmony with Hindus. "If you will act as enemies, we should also react like enemies," he said.

Earlier, Bengaluru BJP MP Tejaswi Surya reportedly called CAA opposers as "puncturewalas".

The nation has been witnessing massive protests against the Citizenship Amendment Act (CAA) and the National Register of Citizens (NRC). But Prime Minister Narendra Modi has specifically stated that the NRC was never discussed.

Bengaluru, Mar 19: Karnataka High Court on Wednesday rejected the plea by Congress leader Digvijay Singh seeking directions to the police to allow him to meet rebel Madhya Pradesh Congress MLAs who are lodged in Bengaluru.

Earlier in the day, Singh said at a press conference, "I have filed a plea in the Karnataka High Court, seeking permission to meet Madhya Pradesh Congress MLAs who are putting up at Bengaluru. I have decided to be on fast and shall take a call on that after the decision of the Supreme Court and the High Court," Singh said at a press conference here earlier.

Singh said, "The BJP is busy in toppling duly-elected governments. We had successfully thwarted their plans to destabilise the MP government but we were let down by Jyotiraditya Scindia who had a very successful career in Congress."

"We never expected that he would ditch us and join hands with the BJP," he added.

The Congress leader also said that the BJP government had become insecure since the Kamal Nath-led government started tightening the laws on mining.

"Chief Minister Kamal Nath drafted a new mining policy for the sand under which the mines were allotted through auction. All this was unpalatable to the BJP and from Day 1 they started offering money to our Congress legislators," he said.

"In BJP, the Atal Bihari Vajpayee's kind of leadership no longer exists. The leadership which controls the BJP now includes people who have joined hands to do all kinds of unscrupulous things which has led to a stage in India where the banks are collapsing, non-performing assets and unemployment are growing," he added.

Earlier today, he was put under preventive arrest after he sat on a dharna near Ramada Hotel here allegedly for not being allowed to meet the 21 rebel Congress MLAs lodged in the hotel.
