Karnataka politician's son in Dubai gets threat calls for anti-JuD video

Bengaluru, Apr 12: As many as 17 new cases of coronavirus were confirmed on Sunday in Karnataka, taking the total number of infected to 232, the health department said.

This includes six deaths and 54 discharges.

According to the bulletin issued by the health department, six cases were reported from Vijayapura, four cases in Belagavi, three each in Bengaluru city and Kalaburagi and one in Mysuru.

Among the 17, four people are suffering from Severe Acute Respiratory Illness (SARI) -- two of whom are in Bengaluru and one each in Vijayapura and Kalaburagi, the department said.

Following the sudden spurt in cases in Vijayapura, the department has initiated contact tracing.

Ever since the outbreak of COVID-19, Bengaluru continued to top the list with 76 cases, followed by Mysuru with 48 cases, Belagavi with 14 cases, Kalaburagi with 13 cases and Dakshina Kannada with 12 cases.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jan 8: The Karnataka government on Tuesday decided to adopt a no-fail approach for Class 7 examinations for government and private schools following the state syllabus.

The report card of a student doesn’t carry ‘pass’ or ‘fail’ remark, but points to his or her strengths and weaknesses in each subject in the exams, which will now be called Common Evaluation Exam.

The quality cell of the Karnataka Secondary Education Examination Board (which conducts SSLC exams) will prepare question papers, which will be evaluated at the district level by government and private schoolteachers. The Class 7 exams will be held in March.

The Common Evaluation Exam follows the Continuous Comprehensive Evaluation (CCE) currently practised under the Right to Education Act. “The formative and summative assessments (tests, projects and quizzes) will be held as usual,”KG Jagadeesha, commissioner of public instruction, said.

Edu dept to launch helpline by March

For the March exam, summative assessment 2 will be held with half the syllabus. Other modalities (exam duration and total marks) will be announced next week,” said KG Jagadeesha. The CCE system will continue for classes 8 and 9. The government hopes the exam and subsequent interventions in classes 8 and 9 will boost students’ confidence for crucial board examinations.

Minister S Suresh Kumar said, “More than an exam, it’s an evaluation of a child’s knowledge. The Belagavi division has done something similar. The Kalaburagi zone found mathematics and science were areas of concern; language was an issue in Urdumedium schools.” The minister said zilla panchayat CEOs have observed that intervention should start from class 8. “Keeping this in mind, we’ve started necessary preparation for class 7 exam ,” he added.

The education department will start a helpline by March for students, teachers, school managements and educationists to 11 raise problems on day-to-day issues.
