Hindu girl from your home town ‘found dead’; where are you: CFI asks DK MP

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Mar 18: Karnataka Congress President DK Shivakumar on Wednesday met the Director-General of Police in Bengaluru and demanded police protection for Madhya Pradesh Congress MLAs and the removal of BJP workers from the hotel in Bengaluru, where the legislators are currently lodged.

"The (Madhya Pradesh) legislators have come here and have requested police protection, that is all. Let the police give them protection, our candidate (Digvijaya Singh) has come, let him meet the legislators. Why are BJP workers protecting them? We know that they are under threat and hence we need to vacate them (BJP workers)," Shivakumar told reporters here after the meeting.

"We will give protection to our men and that is why we are telling them they cannot stop us. They should be in a free and fair position. I have communicated to DGP that BJP needs to vacate," he added.

Earlier today, Congress' Rajya Sabha candidate from Madhya Pradesh and former chief minister Digvijaya Singh was placed under preventive arrest after he sat on a dharna near Ramada Hotel here, allegedly for not being allowed by police to meet the 21 Congress rebel MLAs lodged in a hotel.

"I am a Rajya Sabha candidate from Madhya Pradesh, voting is scheduled for March 26. My MLAs have been kept here, they want to speak to me, their phones have been snatched, the police is not letting me speak to them saying there is a security threat to MLAs," Singh told reporters.

Singh who sat on the dharna with a face mask on said: "We were expecting them to come back, but when we saw they're being held back, messages came from their families...I personally spoke to five MLAs, they said they're captive, phones snatched away, there is Police in front of every room. They're being followed 24/7," Singh said.

The development comes amid the political crisis in Madhya Pradesh after the exit of Jyotiraditya Scindia from the Congress party.

Scindia's departure was followed by 22 Congress MLAs resigning from the party as well as from the state legislative Assembly.

The resignation of these MLAs has left the Kamal Nath government below the majority mark.

Chikkamagaluru, Feb 19: A 31-year-old homemaker was murdered and valuables, including 100gm of gold and 2kg of silver, were reported missing from her house in Kadur town of Chikkamagaluru district late Monday evening. Her 11-month-old son, who was with her at the time of the attack, had a miraculous escape.

Police said Kavita's husband Dr Revath was away in his clinic in the town's Kadur-Birur road along with their first son, 5. Kavita, who has done MA and from Udupi, and the dentist married seven years ago.

District superintendent of police Harish Pandey has formed a special team to probe the incident that took place in Lakshmish Nagar in the town.

According to police, Kavita spoke to her husband around 6.45pm on Monday and didn't answer his subsequent calls, triggering a strong suspicion in him that something was amiss. He called his relatives living nearby to check on his wife. The relatives rushed to the house only to find the main door locked.

Since Kavita didn't answer the doorbell, they force-entered the house from the rear door and found her in a pool of blood. She was taken to a private clinic where doctors declared her brought dead.

Police said the woman was killed by a sharp weapon by slitting her throat between 6.45pm and 8.15pm. The rooms and almirahs had been found ransacked. At least 100gm gold ornaments, 2kg of silver and cash were missing from the house.
