Mangaluru: Over 7K screened for coronavirus at Airport; over 1K at port

Udupi, Apr 21:  Four walk-in sample collection units for COVID-19 test has been installed in the district, sources said on Monday.

The units have been installed at Udupi’s T M A Pai Hospital and district hospital and at Kundapura and Karkala taluk hospitals by Indian Medical Association, Udupi Branch along with Rotary Club and Red Cross Society.

Udupi district was declared COVID-19-free after all three COVID-19 positive patients were discharged after recovery and were now in home quarantine, the sources added.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Belgaum: Canon, Epson and Nikon reside in a house named "Click" in Karnataka's Belgaum district.

The newly built house of photographer couple Ravi and Krupa Hongal, which resembles a giant DSLR camera, has not only enamoured locals but has become quite a sensation on social media.

The three-storied camera-shaped house located in Shastri Nagar is an expression of passion and love for the art of photography of the couple whose children- three boys- have all been named after the iconic camera brands.

Their names ''Canon'', ''Epson'' and ''Nikon'' feature prominently on the house whose exterior resembles a camera. Just like a camera, the building has a glass window shaped as a viewfinder and another as a lens. It sports a wide film strip, a flash and even a memory card.

The walls of the house walls and its interior have graphics related to photography.

"I have been photographing since 1986. Building this house is like a dream come true. We also named our 3 children-Canon, Nikon and Epson. These all are three camera names. I love the camera and hence named them on camera companies name. My family were opposed to it, but we remain adamant," photographer Ravi told media persons.

The photographer says the couple had to borrow money from relatives and friend for constructing the house. "We also sold our previous house to build this house," he added.

Krupa said that it was their cherished dream to build a house like a camera.

"My husband is a photographer. It was our dream to build a house like a camera. We planned and built this house. We feel like we are living inside a different world, inside a camera. I am very proud of my husband," she said.

Canon, their elder child said, "My friends used to ask me whether it was my real name. Now, I tell them yes, photography is my father's passion and hence he named me Canon."

On social media, the picture of the unique shaped house has been shared widely.

"This is called love for the passion," said one user on Twitter.

Another user commented: "A camera-obsessed photographer from India builds a camera-shaped house! 49-year-old Ravi Hongal has spent over $95,000 building the 3-story house, which looks like a camera in the town of Belgaum in India."

The family seems to be indeed living a picture-perfect dream.
