Protests erupt across Dakshina Kannada, Udupi against arrest of PFI leader

Bengaluru, May 17: Left to itself, Karnataka will look to spring back towards normalcy under Lockdown 4.0 as the state government is on standby to resume public transport services from May 18, if the Centre allows it. 

Though KSRTC and BMTC have been preparing for resumption of services, officials in the two corporations told DH that they cannot make a move till the government makes a decision.

Transport Commissioner N Shivakumar said the department will take a decision based on the state government's orders. "The government will take a call on buses as well as taxi and other transport services," he said.

Senior officials in the state government said Deputy Chief Minister and Transport Minister Laxman Savadi has written to Union Minister for Road Transport and Highways Nitin Gadkari seeking a nod for resumption of the services. 

Transport Secretary Gaurav Gupta has written a separate letter to his counterpart in the Union government requesting permission to operate public transport. "The state government wants the services to open. The official has listed out the steps the corporations will take to ensure social distancing other steps that will be taken to check spread of Coronavirus," a source said.

The B S Yediyurappa administration has been bullish on easing lockdown restrictions. 

If the Centre empowers the states to define Lockdown 4.0, Karnataka is likely to do away with the red-orange-green zoning of districts and allow public services to resume, except in COVID-19 containment zones. The government is also likely to redefine its containment strategy by micromanaging localities where COVID-19 cases are reported, without letting life in an entire district get affected. 

The government has already shown willingness to allow hotels and gyms to open after May 17 subject to social distancing norms and restrictions. In fact, the government has proposed to allow the resumption of all economic activities in standalone establishments. The government, however, is not keen on opening malls, theatres, diners and establishments that have centralized air conditioning. 

“Everything depends on the Centre,” Deputy Chief Minister CN Ashwath Narayan said. “Our only stand is that the red zone should be treated at par with the other zone when it comes to relaxation.” 

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

Krishnagiri, Feb 24: Vidya Rani, daughter of dead sandalwood smuggler Veerappan, joined the BJP on Saturday at an event organised in Tamil Nadu's Krishnagiri.

Party general secretary Muralidhar Rao and former Union Minister Pon Radhakrishnan were present at the event.

"I want to work for the poor and underprivileged irrespective of their caste and religion. Prime Minister Narendra Modi's schemes are for the people and I want to take them to the people," said Vidya Rani.

Besides Vidya Rani, the event saw as many as 1,000 members from other political parties join the BJP.
