Ramanath Rai called Poojary “Ra***maga”: Harikrishna Bantwal

Mangaluru, May 2: The Dakshina Kannada district administration is gearing up to make necessary arragements at the Mangaluru International Airport as the Centre has shown green signal to bring back stranded Indians from the Gulf countries. 

Karnataka is making efforts to bring back 10,823 people stuck abroad. Apart from Mangaluru, Bengaluru Airport also will be used. As many as 6,100 people will be transported in first stage with speical flights. Soon after their arrival, the administraion will send them to compulsary quarantinement in Dakshina Kannada, Udupi, Kodagu and other neighbouring districts.

Dakshina Kannada MP Nalin Kumar Kateeel said that the govt has made elaborate arrangements to conduct medical test on arrival at the airport. As per plan, based on medical check-up, they will be categorised as group A/B/C. Later, they will be quarantined for the mandated days, he added.

The following is the break-up Kannadigas stranded abroad: 4,408 people are tourists/visitors, 3,074 students, 2,784 migrants/working professionals and 557 shipping crew.

Countries from where stranded people will be brought back to Karnataka in the first stage include Canada (329), the US (927), the UAE (2,575), Qatar (414), and Saudi Arabia (927).

Bengaluru, Apr 13: Karnataka Chief Minister BS Yediyurappa today held a review meeting with his cabinet colleagues and senior officials regarding prevailing coronavirus situation and several other important issues in the state.

Chief Secretary TM Vijay Bhaskar was also present at the meeting. The possible situation once the COVID-19 lockdown is lifted was discussed along with the financial status of the state government and how to mobilise additional resources, sources said.

The Chief Minister also appealed to sugar factory owners to clear the pending payment to the tune of Rs 2834 crore to farmers in 11 districts. He also said that the government has released Rs 45 crore compensation to farmers for loss of paddy crop in Raichur and Koppal District due to hailstorm based on a report submitted by District Collectors.

Amid the lockdown distribution of free milk to the poor will also be continued for one more week, sources added.

The meeting also decided to speed up disposal of cases related to the regularisation of unauthorised constructions which are pending before the High Court and Supreme Court.

In addition to this, the government is planning to auction more than 12,000 corner sites lying idle in Bengaluru. An amendment to the law governing permission to allow sites in private and co-operative housing societies will be made. Hundreds of societies are waiting for approval from the government for releasing the sites, sources said.

It was also decided to utilise Rs 1,000 crore available at Rajiv Gandhi Health University to upgrade medical college hospitals.

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
