No ease of living in Karnataka, seven cities rank below 40, score low on all indicators

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Apr 4: As calamity struck the nation in the form of coronavirus, many philanthropists have generously opened their wallets to sustain the urban poor, especially the migrant labourers in the city and elsewhere in Karnataka.

These individuals either directly or through organisations opened up their kitchens to ensure that no one goes to bed hungry in this distressing time.

The Bruhat Bengaluru Mahanagara Palike, the nodal agency to feed urban poor, responded positively to requests by these organisations and individuals to supply food to the needy on their behalf.

"We had been serving food through our Indira canteens, which we continue to do even now. However, many philanthropists and corporates have come forward to feed the needy," the BBMP joint commissioner Sarfaraz Khan told reporters.

According to BBMP, Indira canteens used to provide two lakh meals a day on normal occasions.

However, since the lockdown has been clamped, the number swelled by almost 50 per cent.

"On Thursday alone, we served 2.85 lakh food, which comprises breakfast, lunch and breakfast," a Palike officer said.

The major aid came from Jain International Trade Organisation (JITO) and Azim Premji Foundation.

While JITO is feeding around 22,000 people, Azim Premji Foundation is taking care of 20,000 people.

Sajjanraj Mehta, an office bearer of JITO, told reporters that his organisation has been providing packaged cooked food since March 27.

"We got in touch with Bengaluru Mayor M Gautham Kumar, Police Commissioner Bhaskar Rao and the BBMP commissioner B H Anil Kumar. According to their list, 27,000 food packets were required daily," Mehta told.

The JITO members have arranged vehicles of their respective businesses to transport food packets to different locations as part of the campaign named as 'COVID-19 manav seva'.

The organisation has also decided to utilise the kitchen of Princess Golf, a marriage hall on Palace Grounds here to prepare food.

Palike officials said on Thursday alone JITO supplied 53,000 meals.

"We asked them to cover migrant labourers in those areas where Indira Canteen could not reach. We mapped the cluster and provided them info. Now, they are distributing it there," they said.

Another organisation engaged in charitable work is ISKCON Bengaluru.

Ever since the lockdown, it has been working in various parts of India providing food to various people.

"We are providing materials such as rice, wheat flour, Daal, oil, vegetables with long shelf life, salt, sugar and spices. Each packet can sustain for at least 21 days," Madhu Pandit Dasa, president of ISKCON Bengaluru.

The organisation has set a target to cover at least two lakh people but so far it has reached out to 30,000 people including 25,000 in Bengaluru alone.

"We are feeding about 50,000 people in Delhi, with the Telangana government we are feeding about 40,000 people in Hyderabad, about 10,000 people in Ahmedabad in association with the Gujarat government," Dasa told.

According to BBMP, other organisations providing food to the needy are KMFY, TVS Group, Vimal Bhandari, Radisson Blue Atria Hotel, Hitech Ecowood, Mohammed Shajid, Prestige Group.

Wipro Ltd also pitched in to feed the poor by opening up its industrial kitchen infrastructure.

In a statement, Global Head- Operations of the company Hariprasad Hegde said the humanitarian crisis we are faced with as part of the Covid-19 crisis has multiple dimensions to it, of which the need to deliver cooked meals to the stranded migrant workers and other vulnerable communities is probably the most critical and immediate one.

Recognising this, Wipro has decided to use the industrial kitchen infrastructure in our facilities to provide cooked meals, he said.

This kicked off on April 2 with the delivery of 43,000 meals from our Bangalore facility in Kodathi to the government.

"We have made use of our own procurement logistics to source the food provisions. This is a collaborative process, with the government taking responsibility for the logistics of last mile delivery to the communities that need it the most,” he said.

In the case of Bangalore, the Karnataka government has come forward to provide this kind of complementary delivery support. We are reaching out to other state governments and local administrations for similar efforts." he said.
