Young Gram Panchayat member ends life by consuming poison

Udupi, Jul 15: Two doctors and four staff members of the Udupi District Hospital have been tested positive for coronavirus.

While one doctor is undergoing treatment at the designated covid hospital, the other one, who is said to be asymptomatic, is being treated at his residence.

After four staff members of the hospital tested covid positive, the throat swabs of their contacts including other staff of the hospital and family members were also sent for testing. 

Meanwhile, a person who was undergoing treatment in the district hospital for some other ailment also tested covid positive triggering panic among other non-covid patients.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 22: People here stayed at their homes due to Janata Curfew on Sunday amid the coronavirus scare.

Prime Minister Narendra Modi had on Thursday urged people to stay at their homes as a precautionary measure against the spread of coronavirus.

"We hope the situation gets better at earliest and everyone gets rid of the virus," Varma added.
"All the shops have been closed.Everyone is at their homes to avoid getting infected from this deadly virus," said Harish Niwasi, another resident.

"Today is PMs Janata Curfew and so we all are at home. I appeal to all that by staying at home we can save each other from the deadly virus. We thank the PM for guiding us at such difficult times," said Tulsi Ram Varma.

The Janata curfew which began at 7 am today will come to an end at 9 pm.

Till now, the total number of positive coronavirus cases in Karnataka is 15 out of which one person has been cured and one death has taken place in the state, according to the Health Ministry.

The Karanataka Health Department on Saturday confirmed five new coronavirus cases in the state, taking the total count to 20.

According to the Indian Council of Medical Research (ICMR), till now there are 341 positive cases of coronavirus in the country.
