Abu Dhabi: Bearys Welfare Forum hosts iftar get-together-2018

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 21: Amulya Leona, a college student, who raised to pro-Pakistan slogans to embarrass organisers of a protest against the Citizenship (Amendment) Act (CAA) here on Thursday evening, has been charged with sedition.

The student-activist, who was allowed to talk on stage, suddenly raised pro-Pakistan slogans. She was arrested by police after All India Majlis-e-Ittehadul Muslimeen (AIMIM) chief Asaduddin Owaisi snatched her mike.

Deputy Commissioner of Police Ramesh Bannoth confirmed the girl has been charged with sedition, provoking enmity between groups, and intentional insult to provoke breach of peace.

It was just after Mr. Owaisi’s arrival on the stage at Freedom Park here that the 19-year-old student was asked to speak. After preliminary remarks, she suddenly shouted “Pakistan zindabad” thrice, leaving the crowd and organisers stunned.

Some of the organisers rushed to her and tried to take the mike away and stop her from speaking further. Mr. Owaisi too joined in and snatched the mike. Holding on to the mike, the girl then went on to shout “Hindustan zindabad” twice, before a posse of police personnel and organisers whisked her away from the stage

Soon after the student was taken away, a visibly upset Mr. Owaisi told the crowd: “Whatever has been spoken [by the girl] is wrong. Neither my party nor I has any connection with it. As long as we are alive, we will be raising Bharat zindabad slogans. Never had we any relationship with Pakistan nor will we have anything in future,” he announced.

He further stated: “This is condemnable. The organisers should not have invited such people to this place. If I had known that these kind of things would be said here, I would not have come here.”

It is unfortunate that the organisers have invited such people and a wrong message is going out, he said. “Now, BJP has got an opportunity and will blame me,” he added.

Every speaker, who took the podium after the incident, condemned the pro-Pakistan slogans raised by Amulya.

Janata Dal (S) councillor representing Gurappanapalya, Imran Pasha, one of the organisers of the protest under “Hindu, Muslim, Sikh, Isayi Federation”, claimed that they had not invited the “activist” and were not aware that she would be speaking from the stage. Mr. Pasha said that such statements were “a deliberate attempt to drive a wedge between Hindus and Muslims”.

Meanwhile, the BJP State unit tweeted, “Truth is that protests against CAA are a joint venture between Pakistan and anti-National forces led by INC India.” In a press release, BJP State unit president Nalin Kumar Kateel termed this as an “anti-national act” and urged the police to take action.
