Will terminate pact if 108 failed to ensure better service: UT Khader

Mangaluru, Jul 21: Private hospitals cannot send back COVID-19 patients for any reason, district in-charge minister Kota Srinivas Poojary said on Monday.

The Minister was addressing a meeting at the Father Muller Medical College here on the arrangements made for COVID-19 patients.

Dakshina Kannada district is quite advanced in the medical field. Hence, the government will not tolerate COVID-19 patients wandering from one hospital to another for treatment. Refusing to admit COVID-19 patients in hospitals is unacceptable, he warned.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 24: Fugitive underworld don Ravi Poojary, with more than 90 criminal charges pending against him, was brought to the city in the wee hours of Monday after he was arrested from Senegal in South Africa.

Police said that he was wanted in more than 92 criminal cases.

"Though Senegal police had nabbed him about six months back to get him to India it took more than six months since there was no agreement to deport criminals from that state to us. However, now all legal hurdles have been removed and we have succeeded in bringing him", a top police official told media.

A team of Bengaluru Police headed by Additional Director General of Police Amar Kumar Pandey, Joint Police Commissioner Sandeep Patil reached Senegal on Saturday and brought him to the city by Air France flight.

Ravi Poojari was wanted in cases of extortion and murder and was active in the Mumbai underworld. He was part of the underworld don Dawood Ibrahim's gang and later is said to have worked with 'Chota Rajan' for some time. Claiming to be an enemy of Dawood, Poojari reportedly finished off all his associates and anti-India elements in the country. His men were involved in a shootout on the Shabanam Developers office in Bengaluru in which a woman staffer was killed.

He is also said have been involved in the shootout case of Shahid Azmi, an advocate from Mumbai. There are cases against him in Kerala, Gujarat, and Maharashtra.
