BJP chief Amit Shah gets rousing welcome at Mangaluru Railway Station

Mangaluru, July 21: Putting an end to all speculations, district in charge minister Kota Srinvas Poojary on Tuesday said that the lockdown in Dakshina Kannada will not be extended beyond Wednesday.

In a video message, the minister said that all the shops in the district will remain open from July 23 morning. He said district administration will make a formal announcement soon.  

Meanwhile chief minister B S Yediyurappa said: “There’ll be no lockdown from Wednesday, people need to get back to work, economy is also very important. We have to fight COVID-19 while maintaining stable economy. Lockdown is not the solution, now restrictions will be placed only in containment zones.”

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jan 3: Former Karnataka chief minister and Congress leader Siddaramaiah on Friday criticised Prime Minister Narendra Modi and said that 90 per cent of the promises made by him remain unfulfilled.

"He (Prime Minister Modi) had promised that in 2020 the economy will be doubled, but only their troubles have doubled. He just lied. 90 per cent of the promises made by Modi have remained unfulfilled," Siddaramaiah told media here.

Siddaramaiah's remarks come at a time when Prime Minister Modi is on a two-day visit to the state.

"In August, there was severe flood in state, he didn't visit Karnataka at that time. Flood situation was in 23 districts. Prime Minister will tweet for small issues. But at the time of severe flood he didn't even tweet. In 2009, Manmohan Singh was the Prime Minister. He did aerial survey of the state and announced Rs 1500 crore relief on spot," Siddaramaiah said.

"This time the estimated damage due to flood is more than Rs 1 lakh crores," he said.

He went on to say, "Prime Minister came to witness Chandrayaan-2. He did not give time to Chief Minister and ministers and opposition party to meet him and discuss about floods."

"When I was the Chief Minister, the Prime Minister visited the state two times. Prime Minister had told at the time of inauguration of food park that there will be 10,000 direct employment and 25,000 employment. But nothing has happened till now," Siddaramaiah said.

Besides the Prime Minister, Siddaramaiah also criticised Chief Minister BS Yediyurappa.

"In last election, Prime Minister had told that, if BJP comes to power in Centre and state, there will be development. But nothing has happened. Chief Minister and ministers should have spoken to the Prime Minister about relief funds. The central government should have announced it as National disaster... That's why I called BS Yediyurappa as weak Chief Minister," Siddaramaiah said.

"He had said if BJP is in power at the centre and state, doors of fortune of the state will be opened. People trusted him and gave 25 seats in Lok Sabha elections. But now, he doesn't even open the doors of his house for his party leaders," he said.

Congress leader further cornered the Prime Minister over his address in Tumkuru Mutt on Thursday and said, "We admit Pakistan is an evil country. But what are you doing about minorities in our country? You are bringing law against the minorities. Is that right? And you give speech about these things in front of young children."

Prime Minister Modi is on a two-day visit to Karnataka and is attending several events as part of his official engagements.
