Adieu Ramadan! Eid al-Fitr in coastal Karnataka on Sunday

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Mar 28: Karnataka Director General of Police Praveen Sood on Saturday asked philanthropists who want to support the poor during the lockdown to leave food at the nearby police station, who will ensure that it reaches the needy.

The DGP has asked the Bengaluru City police Commissioner to take steps in this regard and ensure fair distribution.

"All philanthropists, in case you want to support poor. Leave cooked, packed, simple food at the police station and it will reach poor. @CPBlr pl announce a nodal officer for deciding the police station for fair distribution," Sood wrote on his official twitter handle.

Responding to the DGP's tweet, city police Commissioner Bhaskar Rao appointed Joint Commissioner (Crime) as a nodal officer.

"Sandeep Patil, IPS, Joint Commissioner, CRIME at 9480801011 is the officer nominated from Bangalore City Police to receive and acknowledge donation of food and consumables for distribution to police and those in need," Rao tweeted.

Meanwhile, the city police has also initiated measures to take those in critical medical emergency to the nearest medical facility.

"We @BlrCityPolice are at your service 24/7 to take you to nearest medical facility in critical medical emergency, dialysis, chemo, emergent heart issues etc PLEASE CALL 100 Misuse may affect someones life! Be responsible #CoronaLockdown is National Duty #Covid19India," Additional Commissioner of Police (Administration), Bengaluru, Hemant Nimbalkar tweeted.

Bengaluru police's initiative of distributing food, snacks, water and certain essential requirements to those in need has received wide appreciation.

While some police stations are already providing food to poor and those in need by collecting it from sponsors, couple of them have even hired a cook for the needy.

The lockdown has affected the poor who depend on their daily wages for livelihood.

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.
