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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Feb 24: The National Investigation Agency (NIA) is conducting raids at more than 20 locations in Karnataka and Tamil Nadu. The latest raids are being carried out in connection with ISIS conspiracy cases.

More details are currently awaited regarding the cases.

Meanwhile, NIA had on February 15 filed a charge sheet against two Lashkar-e-Toiba (LeT) terrorists before the agency special court, Jammu. The two terrorists are identified as Khalil Ahmad Kayani (34) and Mohammad Nazeem (23), both residents of Haveli Farwad Kahuta district in Pakistan occupied Kashmir (PoK).

The case is related to the arrest of the two accused near Nilkanth Nala, approximately 700 metres inside the Indian side of LoC, in Gulmarg Sector of Baramulla district.

The Bharatiya Janata Party workers belonging to Muslim community are bewildered over the contentious Citizenship Amendment Act. A considerable number of BJP’s Muslim workers have distanced themselves from the pro-CAA meetings being organised by the party in different parts of India.

There is a deep divide within members of the BJP minority wing, with many upset and angry with the party. During its membership drive in 2018 for the minority wing, BJP had enrolled lakhs of Muslims across India.

A senior Muslim member of the saffron party in Hyderabad explained, “We are very upset. There is no one listening to us within the party. Majority of the members are introspecting on their future role in the party. Few are vocal about it. Those, who believe they still have a future in the party, have decided to keep quiet on this issue.”

This is the reason why they are not attending the pro-CAA rallies or interacting with people. If anybody approaches and questions them about CAA, they maintain they have no idea, just like the common man. A member of the BJP belonging to the minority community says they have been hurt by the decision of the government on CAA.

“Shia Muslims in Pakistan are suffering. They have been targeted in that country from time to time. The BJP patronised a large number of Shia Muslims. The Shia community in Uttar Pradesh even sided with the BJP. But what has the community got in the end? The persecuted Shia minorities in Pakistan have not got justice,” the party member from minority community lamented.

There are 400 families belonging to the Shia community in Hyderabad, who have relatives in Karachi and Quetta in Pakistan. These Shias had migrated to Pakistan from the Nizam state after its accession to India. These families were hopeful that after aligning with BJP, there would be a reprieve for them. But the stand taken by BJP has left them in lurch. The CAA provides for granting Indian citizenship only to non-Muslim minorities from Pakistan, Afghanistan and Bangladesh.

“We have been left with nothing. Shias have not been politically active in all the three countries of India, Pakistan and Bangladesh and have suffered due to this reason. There was some hope in India, but even that has been lost now,” the minority wing leader remarked.

National vice president of BJP minority cell Farid Sheikh Liaquat Ali says, “Party workers and common people are asking the same question.”

I have told them what union home minister Amit Shah has said in Parliament, that CAA is not against Indian Muslims. But people are not convinced. Every meeting or social function that I attend, I find that people are angry and upset. I have been with the BJP for 33 years and whatever I hear from the people is being conveyed to the party.”

The incident that occurred at the madarasa in Uttar Pradesh has led to a pointed question: “If this can happen to Muslims in UP, will it not repeat elsewhere?”
