'I have failed as an entrepreneur… I gave up': V G Siddhartha’s alleged letter goes viral

Bengaluru, Mar 12: Karnataka government on Wednesday issued a temporary regulation -- Karnataka Epidemic Diseases, COVID-19 Regulations, 2020 -- which aims to prevent the spread of the disease.

According to the regulation, all government and private hospitals should have flu corners for the screening of suspected cases of COVID-19.

All hospitals during the screening of such cases shall record the history of travel of the person if he or she has travelled to any country or area where COVID-19 has been reported in addition to the history of coming in contact with a suspected or confirmed case of COVID-19 shall be recorded.

Any person with a history of travel in the last 14 days to a country or area from where COVID-19 has been reported must report to the nearest government hospital or call at toll-free helpline number 104 so that necessary measures if required, may be initiated by the Department of Health and Family Welfare.

If a suspected case of COVID-19 refuses admission or isolation, the offices authorised under Section 3 of the regulation shall have powers to forcefully admit and isolate such case of a period of 14 days from the onset of symptoms or till the reports of lab tests are received, or such period as may be necessary.

No person, institution or organisation shall use print or electronic media to spread misinformation on COVID19. If a person is found indulging in any such activity, they will be punished.

If the cases of COVID-19 are reported from a defined geographic area, the district administration of the concerned district shall have the right to implement the following containment measures but not limited to these in order to prevent the spread of diseases:

* Sealing of geographic

* Barring of entry and exit of the population from the containment area

* Closure of schools, offices and banning public gathering

* Banning vehicular movement in the area

* Designating any government or private building as a containment unit for the isolation of cases

* The staff of all govt departments shall be at the disposal of the concerned district administration of the concerned area for discharging the duty of containment measures

Any person, institution or organisation found violating any of these regulations, shall be deemed to have committed an offence punishable under section 188 of the Indian Penal Code (IPC).

Shivamogga, Jun 13: Senior BJP leader and Karnataka Minister for Rural Development and Panchayat Raj, K S Eshwarappa on Saturday opined that during the selection of candidates to the legislative council, the party needs to take into consideration those who helped the party in formation of government in the State.

Speaking to media persons on the sideline of a programme here, he said the party high command would give another surprise while issuing tickets during the MLC election.

Mr Eshwrappa said that party high command will take a call on selecting candidates, but priority should be given to the leader who won on Congress and Janata Dal and then jumped to BJP which helped to form govt under the leadership of B S Yediyurappa.

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
