Now C T Ravi accuses HDK of tapping phones of Congress, BJP leaders

Mangaluru, Mar 22: A video being circulated in the social media purportedly of a man infected with COVID-19 at a hospital here is fake, its authorities said.

The video which shows a youth, dressed in pink trousers and wearing a mask, struggling to breathe on a blue hospital bed, had gone viral after which the Wenlock hospital issued a clarification.

The video started circulating after Dakshina Kannada Deputy Commissioner made public Sunday that a person has tested positive for coronavirus at the hospital.

"A video of a patient convulsing on a hospital bed is being circulated on social media. This video is not of Wenlock hospital. Besides, we do not use blue beds," the hospital said in a statement, adding that they will file a complaint with the police regarding the video.

The first COVID-19 case in the district was confirmed at the hospital on Sunday.

The 22-year old man who came here from Dubai was tested positive and is under treatment in the isolation ward.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 18: The ruling Bharatiya Janata Party (BJP) nominated Prathap Simha Nayak, M.T.B. Nagaraj, R. Shankar and Sunil Valyapure to contest in the June 29 biennial elections for 4 of the 7 Karnataka legislative Council seats, an official said.

"Our high command selected 3 of the 4 candidates the state core committee recommended on Tuesday, excluding H.R. Vishwanath, a former Janata Dal-Secular (JD-S) rebel, who lost in the December 5 Assembly by-elections from Hunsur in Mysuru district on a BJP ticket," a party official said.

Nagaraj, a former Congress rebel, who also lost in the Assembly by-election from Hoskote in Bengaluru Rural district on a BJP ticket, was the state housing minister in the 14-month-old JD-S-Congress coalition government, which fell on July 23, 2019 after 17 of their rebels resigned then.

Shankar, who was an Independent and a minister in the former coalition government, was not given the BJP ticket to contest in the December Assembly bypolls though he too resigned from the Ranebennur assembly seat in Haveri district, about 340km northwest of Bengaluru, along with former Congress and JD-S rebels.

Valyapure is the party's grass-root leader from Chincholi in Gulbarga district in the state's northern region, about 586km from Bengaluru.

Valyapure extensively campaigned in the May 2019 general elections and ensured the victory of BJP candidate Umesh Yadav from the reserved Gulbarga Lok Sabha seat, defeating Congress senior leader Mallikarjun Kharge.

Nayak is also the party's grassroot cadre who rose from the ranks to become its Dakshina Kannada district president in the state's coastal region.

As the ruling party has 116 legislators in the 225-member Assembly, all its 4 candidates will need 28 votes each to win the contest.

Of the 7 outgoing Council members, 5 are from the Congress and one each from the Janata Dal-Secular (JD-S) and an Independent.

With 68 lawmakers, the Congress will be able to retain 2 seats and the JD-S one as it has only 34 legislators in the lower house.

The Congress has nominated its outgoing Rajya Sabha member B.K. Hariprasad and outgoing Council member Naseer Ahmed to contest for 2 Council seats.

Of the 75-member Council, the opposition Congress has 37, BJP 19, JD-S 16, two Independents and one Chairman.
