Another 13 new smart cities announced; Mangaluru continues to wait its turn

Chithradurga, Mar 25: COVID-19-positive cases in Karnataka jumped to 42 from 33 on Tuesday, with nine cases added to the list overnight. The daughter of G M Siddeshwara, Davanagere MP, is the latest case.

Sources from the Siddeshwara family said that the MP’s daughter, along with her two children, who started from Guyana, first landed at New York airport and from there, she took a flight to New Delhi.

From Delhi, she flew to Bengaluru. And then, she and her children travelled with her father in a chaffeur-driven car on March 21 to their house in Bheemasamudra.


Siddeshwara said that protocol for COVID-19 had been followed and all who returned were under self-quarantine at his house. However, the administration was not informed of her travel history till the samples were given for test, Chitradurga Deputy Commissioner Vinoth Priya R told TNIE. The DC said the test results of the MP’s daughter were collected by district health authorities and sent to Shivamogga Institute of Medical Sciences on March 22.

The test turned out to be positive for COVID-19 and she was shifted to the isolation ward at Chigateri district hospital in Davanagere. This is the first positive case in Chitradurga.The patient, who is the wife of an Indian Diplomat in Guyana, complained of flu-like symptoms and remained self-quarantined at her house at Bheemasamudra. Her condition was informed to the health department, which collected her samples and forwarded it to the SIMS for tests, results of which arrived on Tuesday evening.

The DC said that samples of family members including the two children, and those working at the MP’s house would be collected and sent for testing to ensure proper protocol is followed. The administration has declared a ‘red zone of a 5km radius around Siddeshwara’s house at Bheemasamudra. DHO Dr Palaksha said that the patient is not suffering any serious problems and is normal. However, we have put her in the isolation ward of Chigateri District Hospital in Davangere, he said.

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

Mangaluru, May 19: In a bizarre incident which exposes the publicity craze of “philanthropists”, members of a city-based organisation returned without disturbing grocery kits after villagers refused to be photographed while receiving them. 

The incident took place at Mukrampady village in Puttur a few days ago. According to sources, a team belonging to an organisation from Mangaluru had visited the village with a letter from their organisation, to distribute grocery kits to families near mosques in the month of Ramadan. 

The team members reportedly insisted the beneficiaries to pose for pictures with the team near a mosque while being given the food kit. The villagers refused to fulfil their wish.

The organisation members then left the place without handing over the Ramadan kits, sources said.
