Another cop dies of covid-19 in Karnataka while undergoing treatment

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, May 16: Health Minister B Sriramulu has sought the aid of Home department for curbing sex work in certain parts of the state - which continues unabated despite lockdown.

“It poses health risks to those involved. I request the department to ensure that the business is prohibited at such a time of crisis,” he stated in a letter to Home Minister Basavaraj Bommai.  

At the same time, in order to ensure the safety of these workers, Sriramulu has asked both the Health department and the Karnataka State AIDS Prevention Society (KSAPS) to come up with a detailed report on rehabilitation of sex workers and transgenders.

The Health minister’s order was prompted by a letter by writer and activist Roopa Hassan. The writer, who was earlier member of a panel (led by actor-turned-politician Jayamala) on the study of issues faced by sex workers, had sought government’s intervention to stop condom distribution to registered sex workers and transgenders, as continuing work during pandemic was posing health risks to the community.

Mysuru, Jan 2: Mysuru-based Karnataka State Open University is gearing up to offer courses online from this year onwards and a proposal in this connection will be placed before the University Grants Commission (UGC) this month, after approval from the board of management.

As of now, the university offers 31 courses, including undergraduate, postgraduate, and diploma programmes.

Vice-chancellor Vidyashankar S Said that the university will submit its proposal to the UGC soon.

“This is being done to make learning convenient and help students study their courses of choices from the comfort of their homes.”

After launching online admissions for courses, this is another step to go paperless and towards an e-campus, the V-C explained.

The university has also proposed to launch 12 new courses for 2020-21.

A proposal in this regard will be placed before the board for approval on Thursday and the same will be submitted to the UGC for its nod.

Prof. Vidyashankar said the these courses will be in addition to the 31 already available.

The new courses include LLM, MA in Education, BBA, BSc, BCA, diploma in Information Technology, postgraduate diploma in Information Technology, BSc in Information Technology, MSc in Information Technology, MSc in Botany, PG diploma in Banking and Insurance, MSc in Zoology, MA in Telugu, Executive MBA, and MSc in Food Sciences and Nutrition.

The new courses had been proposed based on students’ feedback and the trend.

The V-C said the admissions for the January cycle have begun and over 380 students had so far taken admissions online.

“We are hoping for good admissions this cycle and are expecting around 12,000 admissions,” he replied.
