Another BJP worker stabbed to death in Kannur

Bengaluru, Jun 29: The results of second pre-university and the Secondary School Leaving Certificate examination results will be out by July last week and August first week, Karnataka Primary and Secondary Education Minister S Suresh Kumar said on Monday.

Instead of giving general promotion to the 10th and 12th standard students as the Central Board of Secondary Education and other states have done, the Karnataka government decided to hold the examination defying the coronavirus scare.

"We are trying to get the SSLC results out by the first week of August.The PUC results will be out in the last week of July," the minister told reporters in Bengaluru.

Amid reports of schools increasing the school fees ignoring the government's direction, the minister said he has got reports that 1,150 schools have increased their fees of which action has been taken against 450 schools.

"We have directed all the schools not to increase the fees in view of the coronavirus scare.

It is a peculiar year.Humanity says no one should increase fees.

We have set up a helpline. If we come across such practices, we will initiate action," Kumar said.

He said an officer has been entrusted to look into the complaints against schools.

Speaking about online classes for kindergarten students, the minister said such classes are not allowed.

The schools can hold talks with parents twice a week about grooming their children.

Kumar said a decision on opening kindergarten schools will be taken after July 5.

He, however, conceded that most parents are unwilling to send their children to school.

The government is gathering the opinion of parents based on which a decision would be taken, he added.

Regarding education to students from Class one to Class 10, Kumar said the Centre has given guidelines, which will be followed.

The state has formed an expert committee to recommend guidelines on education to children from Class I to Class six.

"Once the committee report comes, we will formulate regulations," Kumar added.

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
