Udupi limps back to normalcy; eight cases registered; Annamalai returns to Chikkamagaluru

Bengaluru, Feb 10: Senior Congress leader DK Shivakumar on Sunday hit out at the BJP and RSS for taking out a route march in Ramanagara against the controversial Jesus Christ statue.

“Just because the BJP won 25 seats in the Lok Sabha polls, Congress workers need not lose hope. If the Congress and JD(S) had worked out a better strategy, the BJP would not have won even 10 seats. We will correct our mistakes,” the former Congress minister said.

After the Lok Sabha polls, the BJP has failed to do well in assembly polls and has been losing power in many states. People are hitting the streets protesting against its policies such as CAA and NRC, he said.

Accusing the BJP and RSS of not being able to digest Congress’ victory in the Bengaluru Rural Lok Sabha segment in the 2019 Lok Sabha polls, he said that the BJP is trying hard to make inroads into the constituency represented by his brother D K Suresh. “Let them take out route march, we don’t care,” he said.

“We all know what the BJP did during the Lok Sabha elections, and the media reported how much money they spent in the elections. What was the Election Commission doing? Was the Income Tax Department sitting with its eyes closed? Why did they conduct raids only in Hassan, Shivamogga and Mandya districts,” he asked.

He alleged that false cases were slapped when him and other leaders, including H D Kumaraswamy, Siddaramaiah, G Parameshwara and Dinesh Gundurao.

Apr 21: An 80-year-old COVID-19 patient has died in Karnataka's Kalaburagi district, taking the death toll in the state to 17, Medical Education Minister K Sudhakar said on Tuesday.

The elderly person was suffering from Parkinson's disease for the last three years and died at a hospital on Monday, the minister said in a tweet.

"The person had developed fever on Sunday and was admitted to the hospital. The patient passed away yesterday at 9 am. Last night at 9 pm the death report came, which confirmed that the person was COVID-19 positive," Sudhakar tweeted.

The total number of COVID-19 infections in the state has crossed the 400-mark, according to last evening's bulletin by the Karnataka health department.

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
