MBBS student hangs himself in hostel room; parents blame ragging

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 11: Janata Dal (Secular) leader HD Kumaraswamy on Monday asked Chief Minister BS Yediyurappa to urge PM Narendra Modi to give a 'COVID Package' to Karnataka.

In a series of tweets, Kumaraswamy said that Yediyurappa should raise the demand during the course of the meeting scheduled to be held today with the PM, which will also be attended by Chief Ministers of other states.

"Prime Minister Narendra Modi will hold talks with CMs from different states on coronavirus control and lockdown today. The state's CM BS Yediyurappa will also be in it. At this meeting, BSY should urge Modi to offer a 'COVID Package' to the state," Kumaraswamy's tweet, roughly translated in English from Kannada, read.

In subsequent tweets, the JDS leader said that, "The central government has set up a PM Cares Fund for the fight against Corona. As MPs, entrepreneurs and citizens have made generous donations. BSY must convince Modi that the state has not received adequate financial support from the Center so far."

He further said that the package could be utilised for "medical procedures", "financial compensation for the affected people."

Kumaraswamy also said that "In addition to the 'COVID Package', other dues from the Center, including GST dues, flood relief, etc should also be asked for by BS Yediyurappa at the meeting with Modi."

PM Narendra Modi will hold a meeting, through video conference, with state Chief Ministers on Monday at 3 pm to discuss the prevailing COVID-19 situation in the country.

The Prime Minister had earlier interacted with Chief Ministers four times over the COVID-19 situation via video conferencing.

The upcoming interaction comes days ahead of the scheduled ending of the nationwide lockdown.

The ongoing lockdown, which was imposed to contain the spread of coronavirus, is scheduled to end on May 17.

Bengaluru, Feb 13: Karnataka Chief Minister BS Yediyurappa on Thursday said the government had initiated measures to implement the Sarojini Mahishi report as the 12-hour Karnataka bandh call by several pro-Kannada organisations under the banner of Karnataka Sanghatanegala Okkoota began on Thursday.

“Government always stood for Kannada and Kannadigas and initiated measures to implement the Sarojini Mahishi report,” Yediyurappa said. Meanwhile, in Bengaluru, Ola, Uber and auto services were affected even though buses were plying as usual. Security has also been beefed up in Bengaluru after stones were pelted at a Tirupati-Mangaluru bus in Farangipet, though no one was injured.

Bangalore University has postponed all postgraduate (PG) exams scheduled for today. A pro-Kannada activist, Praveen Shetty, was kept under house arrest and police have detained a few people, including those involved in Cauvery protests and other bandh cases.

The organisations are demanding the implementation of a report by former union minister Sarojini Mahishi that recommends a certain percentage of jobs to Kannadigas in public sector undertakings, private companies, and multinational companies. The report was submitted in 1984 but is yet to be implemented.
