Udupi, Jul 14: Kundapura police in Karnataka have booked a case against a businessman who had violated home quarantine rules as many as 163 times.

Accused Sahab Singh had arrived at his rented house at Koteshwara from Mumbai on June 29. He was asked to remain quarantined in his house till July 13. 

However, he was found loitering and visiting hotels in Udupi. Officials tracked his movement through mobile GPS. He breached the quarantine period 163 times. 

Following the violation, Flying Squad officer N G Bhat filed a complaint against Singh in Kundapura Police Station under IPC Sections 269, and 270.

Bengaluru, Apr 9: A special task force--set up by the government of Karnataka--submitted a report to the Chief Minister of Karnataka BS Yediyurappa, putting forward recommendations suggesting minimisation of restrictions in districts where there is nil or minimum cases, here on Wednesday.

The committee said: "COVID-19 and non-COVID-19 patients should be segregated and online health services should be encouraged. Restrictions should be minimised in districts where there is nil or minimum cases of COVID-19 and lockdown should be continued in hotspot areas with quarantine measures strictly being implemented."

With regards to the testing of likely patient, the committee informed that rapid test kits would help to quarantine more likely patient. "The rapid test kits will arrive in April 12. These kits will boost our facility and would help us in quarantining the more people."

On the subject of lifting transportation ban, the committee suggested that the transport of goods and services must continue but with regards to passenger carriers, they are suspended till April 30.

"Goods and Transportation should be allowed, but passenger carriers should be banned until further orders. No buses, trains nor flights will be plying till April 30. No metro trains and auto-rickshaws should be allowed and an odd-even system transport system should be implemented," the committee added.

The committee also suggested that all industries, IT, BT and Garments should be made to work on 50 per cent strength. Garments workers should be allowed to stitch PPEs, which are in more demand. And for construction workers, the committee suggested that they should be allowed to work at sites at 50 per cent strength.

They suggested that educational institutions remain closed till May 30 and online classes must be encouraged.

Dr. Devi Shetty heads the Taskforce and Dr. C. N. Majunath, Dr. Nagaraj, Dr. Ravi and Sudharshan were also the part of the committee.

According to the Ministry of health and family welfare, 181 cases have been reported in the state so far. A total of 5,734 positive cases have been reported of which, 166 are dead and 473 are cured/discharged and migrated.

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
