Karnataka Govt firm on Tipu Jayanti despite intelligence warning

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Apr 17: The Ministry of Information and Broadcasting on Thursday served a show cause notice to a Kannada news channel for broadcasting a programme in which it purportedly said that the Centre would 'air drop money' to the poor, owing to the COVID-19 lockdown.

The notice said that the channel was "spreading false information, creating panic and social unrest.

" The channel had allegedly aired a show titled, "Helicopter Money" on Wednesday which claimed that the Centre would drop money from helicopters during the lockdown period.

A Twitter user took a serious note of it and complained to the Union Minister for Information and Broadcasting Prakash Javadekar.

The fact check team of the Press Information Bureau, under the Ministry of Information and Broadcasting, refuted the claim.

In its notice to the channel, PIB said, "You are hereby directed to show cause why your channel should not be taken out of air immediately. You are instructed to send your reply in this regard within 10 days of receipt of this notice."

Reacting to the notice, the management of the news channels said, "A programme which has been seen in bits and pieces and those who have not even seen the programme appears to have complained. Notice will be replied accordingly."

Vijayapura, June 16: Even as a video of a man wearing a burqa who is being thrashed by locals is going viral on social media, netizens targeted Bharatiya Janata Party for their activist resorting to heinous acts. 

The man who was caught in burqa has been identified as Siddu Paragond, an activist of Snagh Parivar hailing from Sindgi town in Karnataka’s Vijayapura district. 

The bizarre incident took place in Sindgi on June 11 outside a bank.

“While people including women were standing in a queue outside the bank, the person in burqa was acting in a suspicious manner. The person was trying to get too close to women which was making them feel awkward,” local residents said.

“Getting suspicious, some locals tried to interact and their suspicion rose with the strange behaviour of the person. Suddenly some men took the person away from the bank and checked only to find that it was a man in burqa. The men thrashed him and handed him over to police,” the sources said.

Confirming this, Superintendent of Police Anupam Agrawal said that the Siddu Paragond has been arrested and remanded to judicial custody. He, however, made it clear that no suspicious objects were found on Siddu. “We are trying to find out the motive for his act,” the SP said.
