Celebrating Tipu Jayanti is like celebrating Aurangzeb's: Mohandas Pai

Bengaluru, Feb 4: Congress leader and former minister U T Khader today demanded an “objective” probe by an IAS officer into the sedition case the police have booked against a school in Bidar for a play students staged on the controversial Citizenship (Amendment) Act.

On January 26, the Shaheen Primary and High School was charged by the Bidar New Town police with sedition on January 26. This was based on a complaint by an Akhila Bharatiya Vidyarthi Parishat (ABVP) worker who claimed that the play staged by the students on January 21 “insulted” Prime Minister Narendra Modi.

On January 30, the police arrested Nazbunnisa, the mother of an 11-year-old student and Fareeda Begum, a head-teacher in the school.

“This shows how today in India and in Karnataka, the BJP is looking to suppress the voices of people. Sedition cases have no value anymore,” UT Khader told a news conference.

“When a complaint on sedition is filed, action must be taken after obtaining legal opinion. But today, a written complaint by any BJP worker is enough to brand someone as anti-national. Even schoolchildren aren’t spared,” Khader said.

“An IAS officer should be appointed to objectively probe this. If something is found, then the police can continue the investigation,” Khader said. “But the government should pressurize the police. We’ve seen what happened in Mangaluru,” he said, referring to the police shootout that killed two people during an anti-CAA protest. “I know it’s difficult for officials to resist political pressure, but a line must be drawn. All officials must come together and send the government a message, that they will not be bogged down to pressure that’s against societal interests,” he added.

Khader said he lacked faith in the BJP government. “That’s because the BJP tends to give election tickets to those who plant bombs,” Khader said, citing the example of terror-accused Bhopal MP Pragya Thakur. “Even the Aditya Rao case (Mangaluru airport bomb planter)...we don’t know what’s happening. They just want to hush it up,” Khader charged.

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, May 7: Karnataka has revised its standard operating procedure (SOP) for international passengers. The first group of passengers will arrive in the state on May 8.

The number of categories has been reduced to two from three. Category A includes passengers symptomatic on arrival while Category B passengers are those asymptomatic on arrival. These are passengers who are either healthy or those having co-morbidities.

As per the revised SOP, the passenger will be released on the seventh day, if tested negative, to strict home quarantine for another seven days with stamping.

This norm is in contradiction to the Ministry of Home Affairs’ SOP for international passengers. As per the MHA’s SOP, the passengers (asymptomatic) will be under institutional quarantine for 14 days. Testing negative after 14 days, they will be allowed to go home and will undertake self-monitoring of their health for 14 more days.

On the contradiction, Pandey said, "We don't take chances as we rely on tests instead of just quarantining. Other states may be depending on just 14-day institutional quarantine."

"GOI SOP doesn't talk about Covid tests on international passengers. We have put an additional safety layer of three Covid tests on returnees -- one on arrival, second from 5-7 days and last on 12th day. This will ensure definite identification of positive cases even if they are asymptomatic and their subsequent treatment. We should look at the spirit behind the order," he added.

On the 14-day additional reporting period for category B, he said, "It is implied as category B patients should report to us for 14 days after their first 14-day quarantine period is over."

Medical Education Minister Dr K Sudhakar said that the State would follow the Centre’s norms.

Till Tuesday, Karnataka’s SOP had three categories. Under Category A (symptomatic), 14-day institutional quarantine at COVID-19 Health Care Centre was mandatory followed by 14-day reporting period. Under Category B (asymptomatic above 60 years with co-morbidities), seven-day institutional quarantine at hotel/hostel followed by seven-day home quarantine and 14-day reporting period had been recommended. The 14-day home quarantine and 14-day reporting period was mandatory for Category C (asymptomatic).
