Covid-19 cases breach 70,000 mark in Karnataka; 61 deaths takes toll to 1,464

Bengaluru, Mar 13: This year, schoolchildren will have a longer summer vacation starting early, thanks to the new coronavirus onslaught. Primary and Secondary Education Minister Suresh Kumar on Thursday announced that schools in Bengaluru Urban and Rural districts will be closed for vacation from Friday.

Classes from LKG to sixth standard will closed for vacations till the schools reopen in June, while students of classes 7-9 will have ‘study holidays’ until their examinations commence (as scheduled by their respective schools). Their summer vacations will begin with the completion of their examinations.

Class 10 students will have their examinations according to the dates scheduled earlier.

“Let us not treat this as a panic reaction or something to cause a scare. This measure is taken as a precaution. A lot of parents were worried about their children. We have already announced the closure of schools from nursery to sixth standards. Now, we are declaring official holidays upto sixth standard. Students of standards 1-6 will all be promoted based on their formative assessment,” said Kumar adding, “no student will be detained in those classes.”

With respect to seventh, eighth and ninth standards, the schools will be closed for study holidays and students will have to return to write their examinations.“We will not interfere in the examination schedules of CBSE and ICSC schools. However, state syllabus schools have to finish their examinations before March 23”, Public Instruction Commissioner KG Jagadeesh said.Just a couple of papers of the PU examinations are left after which their holidays will begin.

Exam timetable not changed

Miscreants are spreading rumours that SSLC examination dates are changed because of the new coronavirus outbreak. However, Karnataka Secondary Education Examination Board director V Sumangala categorically said the examinations will be held from March 27  to April 9 as scheduled earlier.

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, Mar 5: Karnataka government on Thursday set aside Rs 400 crore to construct twin towers building with 25 floors here at Anand Rao Circle to facilitate all government departments to function at one place.

"To facilitate all the Government Departments to function in one building, a "Twin-Towers" building with 25 storeys will be constructed at Arland Rao Circle, Bengaluru, with an expenditure of Rs 400 crore," said Karnataka Chief Minister Yediyurappa while presenting the budget in the state Assembly.

He further said that the road cross-over facility for pedestrians other than metro commuters will be provided through 24 metro stations.

"The construction of 56 km long Outer Ring Road - Airport Metro from Central Silk Board junction to Bengaluru International Airport via K R Puram and Hebbala at an estimated cost of Rs 14,500 crore will be commenced during the year 2020-21," he said.

Rs 1,000 crore budget each have been announced for the restoration of Bengaluru roads for two years, 276 Karnataka public school for their infrastructure development.
