Patna, Mar 31: In arguably the first of its kind incident in the country, a young man in Bihar was beaten to death precisely because he had informed the district control room about two corona suspects who had arrived here in the State from Mumbai.

The incident took place in Sitamarhi in North Bihar where a 20-year-old youth Bablu Kumar was allegedly killed by Sudhir Mahto and Munna Mahto.

The two Mahtos had arrived from Mumbai to Sitamarhi around ten days back. Bablu, in the meantime, informed the district control room about the arrival of two persons from a State where a large number of people were afflicted with coronavirus.

A team of doctors on March 24 reached Runnisaidpur in Sitamarhi to examine the two suspects. Three days later, these two persons from Maharashtra tested negative.

But the incident (of informing control room and subsequent medial test) created such enmity between the family of Mahtos and Babloo that on Sunday when they found the 20-year-old young man sitting alone, they thrashed him so mercilessly that he died on the spot.

Shocked and grief-struck, Babloo’s father Vinod Singh eventually lodged an FIR with the police and named Sudhir Mahto, Munna Mahto, and their family members as accused in the killing of his son.

The police on Monday raided the place and arrested the Mahtos.

But then, this is not an isolated case of violence. In another incident that took place in Bihar’s Jehanabad district, a BDO Ajay Kumar and a police officer Chandrashekhar Kumar were attacked by fellow villagers when the officials reached there to quarantine those migrants who had reached there from Delhi. So angry were the villagers with the officials’ move to isolate the migrants that they smashed the window-panes of the government vehicles and attacked the officials.

The officials had to beat a hasty retreat. But they soon returned with additional police team which used brutal force and took local leaders into custody before restoring normalcy in the area.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 30: Bengaluru City civic body Bruhat Bengaluru Mahanagara Palike (BBMP) has slapped a fine of Rs 50,000 on the food delivery startup Swiggy for irresponsible disposal of waste, an official said on Friday.

"Thinking of food is great - Swiggy. Hope you also think of segregating waste and disposing of it responsibly," tweeted BBMP Solid Waste Management Special Commissioner D. Randeep.

Randeep said a penalty of Rs 50,000 was imposed on Swiggy Kitchen at Katriguppe in the city for the violation.

"The incident with respect to waste segregation has been brought to our notice and happened at one of our kitchens in Bengaluru," confirmed a Swiggy spokesperson to IANS without revealing the exact details.

He said the startup is aware of its civic responsibility and has stringent processes to ensure high standards of compliance.

"While we investigate and rectify the root cause of the matter, we are reinforcing necessary awareness on the best practices to be followed amongst our teams and partner network to ensure complete compliance with waste management," the spokesperson added.

Swiggy has been penalised earlier as well for its irresponsible disposal of waste.

Recently, the BBMP’s solid waste management department has also fined an apartment complex Rs 15,000 for not segregating waste into dry, wet and reject categories.

Waste disposal norms for apartments

"Segregation of waste is mandatory in apartments. Onus of enforcing segregation rules lies on the (apartment) association and waste should be segregated as dry, wet and reject," said Randeep.

InClover Grand Apartments at Baiyappanhalli was penalised for the offence of improper waste disposal. Similarly, BBMP marshals also caught and fined some people openly discarding waste in public spaces.

"Dear citizens, please change your old habits. Our marshals are watching and will fine those who throw garbage in public spaces," BBMP Special Commissioner Randeep said.

He shared the photographs of two scooter-borne individuals being caught in the act and penalised at Kuvempunagar in Bengaluru.
