Home stay attack: Court grants bail to prime accused

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

It has been 33 years since the night of 22 May, 1987 when nearly 50 Muslim men from Hashimpura, a settlement in Meerut were rounded up and packed into the rear of a truck of the Provincial Armed Constabulary (PAC), an armed police of Uttar Pradesh. It was the blessed month of Ramadan and all the Muslims were fasting.

That night 42 of those on board the truck were killed in two massacres in neighbouring Ghaziabad district. One along the Upper Ganga canal near Muradnagar, the other along the Hindon canal in Makanpur, on the border with Delhi.

The cops had returned home after dumping the dead bodies into the canal. A few days later, the dead bodies were found floating in the canal and a case of murder was registered. 

Vir Bahadur Singh was the chief minister of Uttar Pradesh and Rajiv Gandhi was the prime minister of India when this incident took place. 

Not much has changed for the survivors and the relatives of the victims even today. The wounds are still fresh. Hashimpura remains devoid of basic municipal amenities, the erring silence on the narrow lanes of the locality amid the activities of a daily life speaks of the horror of the fateful day in 1987.

The massacre was the result of one among the many outcomes of the decision taken by the Rajiv Gandhi government to open the locks of Babri Masjid. After a month of rioting, the situation was tense in various parts of Meerut, and a lot spilled over in the nearby areas.
