Zakir Naik slaps Goswami with Rs 500-cr defamation notice for hate campaign'

Bengaluru, Apr 7: The Karnataka Government indicated today that it is too early to take a call now on lifting the nation-wide lockdown but said it’s in favour of its extension in COVID-19 hotspots in the country by at least an additional two weeks.

“We need to see for another few days before taking final call,” Medical Education Minister Sudhakar K, who is in-charge of all matters related to COVID-19, told news agency Press Trust of India when asked if the State is in favour of the rollback after the 21-day period ends on April 14.

The minister opined that the decision on its withdrawal should be based on the COVID-19 pandemic situation at the time in terms of number of cases and response to the outbreak.

When the lockdown is lifted, it has to be in a staggered and phased manner, and not at one go, Mr Sudhakar stressed.

“Where there are red alerts and zones, those zones, in my opinion, should continue to be in a lockdown situation at least for two weeks…till this month-end, I will request them (the Centre) to do this,” he said.

The Telananga Chief Minister K Chandrasekhar Rao on Monday appealed to the Prime Minister Narendra Modi to extend the 21-day national lockdown imposed to contain COVID-19 outbreak beyond April 14, saying it was essential to save lives.

Mr Sudhakar said the Karnataka government is facing financial challenges because of drastic fall in revenues due to the lockdown, adding, it would take “tough decisions” to cut expenditure.

The Finance Department is in the process of evaluating the state’s fiscal position.

“Finance department is gathering information…what is the need now, what should be the overall expenditure, how much we can save; financial support for unorganised and organised sector, along with stimulus to other sectors, we have to see where we stand financially,” the minister said.

“Based on that, we have to take certain steps for sure because after all the government runs on the exchequer money. Once the exchequer is stopped because of lockdown, we are not getting GST, no motor vehicle tax. No tax money is coming.”

Government also has to run right? he said.

He said commitment and obligations with regard to paying interest on loans taken at the national and international level would have to be met.

“So, there are some financial constraints, and financial challenges before the government. The Government will take tough decisions only after studying the entire finance (position of the State).”

The Telangana government last week announced pay cut for government employees.

The Union Cabinet on Monday approved a 30 per cent cut in salaries of all Members of Parliament and a two-year suspension of the MP Local Area Development (MPLAD) scheme.

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

Kasaragod, Apr 30: The Kasaragod District Collector Sajith Babu, his gun man and driver has entered in quarantine on Wednesday.

According to sources, the Collector had been asked to go on quarantine after the reports of a journalist, who interviewed him, was tested positive for the virus.

Chief Minister Pinarayi Vijayan at his routine evening press conference revealed the positivity of the journalist.
