New twist to missing case: Rider found alive in Kundapur

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 29: Indian women have always been the epitome of beauty, strength, and intelligence. Today, the success of Indian women across various walks of life has proven that they have earned this reputation.

One such dedicated social worker is Dr Sunitha Manjunath, the Founder of 'Sumanaa Foundation' of Sanjay Nagar in Bengaluru.

Sumanaa Foundation, based out of Sanjay Nagar in Bengaluru has been on the forefront to support people in distress due to COVID-19. 

The foundation under the leadership of its founder Dr Sunitha Manjunath procured a total of 20000 kgs of farm-fresh produce in four phases from farmers who are unable to sell it due to the COVID Lockdown and have distributed it across 6000 families across Bengaluru city.

"We have procured these vegetables after identifying farmers who are unable to sell their produce due to the challenges of lockdown.

This initiative not only supports the farmers by helping them get the right price for their produce, but also gives us an opportunity to get vegetables at a reasonable price by escaping all middlemen and commissions. We have identified 6000 poor families mainly around Bengaluru city who have not been able to earn their daily wages and given them coupons.

The foundation members identify genuine cases and give them coupons which can be redeemed in exchange of an essential vegetables kit," said Dr Sunitha Manjunath, the founder of Sumanaa Foundation.

These vegetables have been procured from Chikkaballapura, Doddaballapura, and surrounding villages and included vegetables like onions, tomatoes, capsicum, green chillies, beans, carrots, brinjal, potatoes, beetroots etc. These farmers got a fair price for their produce and were overjoyed to know that their harvest is being distributed free of cost to needy and deserving families.

Sumanaa Foundation has been actively supporting the city administration in fighting COVID-19 pandemic. In the recent weeks the foundation has distributed sanitisers and masks to BBMP Pourakarmikas.

The foundation also cooked food for over 400 people each day. This food was handed over to the city administration, which further distributed this to the police department and other staff working across government departments during these testing times.

Dr Sunitha, an engineer by qualification, had enjoyed a high-flying corporate career with BOSCH. She was offered a global role, which she turned down to setup her NGO, 'Sumanaa Foundation' and to serve the needy in and around her locality. Over the past seven years, the NGO with 70 members has done a wide range of activities to support the poor and needy in Bengaluru.

The core team of Sumanaa Foundation works under the leadership of its president Dr Sunitha Manjunath and includes young and energetic individuals like Manjunath K, Prakash K, Vidya Prakash, Sindu Gowda, Byregowda, Nishita Arjun, Arjun Varadaraj and Manoj Kumar
'Meal of Humanity' is a notable initiative of Dr Sunitha Manjunath and her team. Under this program, over 300 poor people are served mid-day meals every day. 

This is currently a self-sustained program with no external funding. Dr Sunitha Manjunath, her family members, and friends contribute their hard-earned money to bring smiles to hundreds of migrant workers and daily wage laborers.

'Wall of Humanity' is another unique concept implemented by Sumanaa Foundation. People can leave used or unnecessary daily use products like clothes, toys, groceries, etc at a designated area. This can be picked by anyone in need of these items. This self-helping model has touched the lives of hundreds of people in and around the area of Sanjay Nagar.

Regular blood donation camps, eye checkups, scholarship for students, tailoring machine distribution, environmental initiatives, Swacch Bharath programs, wall painting across the roadside are just a few among the hundreds of activities undertaken by Sumanaa Foundation regularly under the leadership of Dr Sunitha Manjunath and her team of friends.

"A life without an aim is worthless and so is a death without achievement. The aim of my life is to touch the lives of the hundreds of people who are not as privileged as you and me. I'd like to thank my husband Manjunath, my In-Laws and my friends from Sumanaa Foundation who work tirelessly alongside me across all our initiatives," said an elated Dr Sunitha Manjuanth on receiving the 'ET Power Icons' award for Excellence in Social Service and Public Initiatives.

Dr Sunitha Manjunath has also been awarded the prestigious 'Kempegowda Award' and many more such awards for her contribution to the society.

Bengaluru, June 1: Prime Minister Narendra Modi today praised the Karnataka government for its handling of the COVID-19 pandemic.

Addressing the silver jubilee celebrations of the Rajiv Gandhi University of Health Sciences (RGUHS) via a digital platform, he spoke about the Karnataka government's efforts.

He appreciated the work of front-line warriors who are fighting every day in the war against COVID-19 and stressed the need to respect them.

"Doctors and other medical workers are soldiers without wearing the uniform of soldiers. Any kind of attack or violence against them is not acceptable," said Modi.

"There are incidents of violence against the front-line warriors. Any kind of abuse, violence or rude behaviour is not acceptable. The world is looking at doctors and medical staff with gratitude," he said.

"This is the biggest crisis since the two World Wars," the prime minister said. "Pre- and post-COVID-19, the world will be different. The discussions now at a global level are humanity-centric."

Stressing the importance of medical infrastructure, the prime minister spoke about the decision taken by the Union Government to set up a medical college in every district.

"A nation like ours has to have the medical infrastructure and medical education. Now, every district is going to have a medical college," he said.

However, the PM remained silent on salaries of front-line warriors. The Karnataka government has so far not released the salaries of doctors, nurses and lab technicians hired under National Health Mission.
