BJP MLA breaks police horse's leg during protest. Animal also anti-national'?

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 25: In the wake of unexpected surge in the coronavirus positive cases in Bengaluru, the special task force team assigned with the task of creating Covid Care Centres (CCC) has made elaborate arrangements the Haj Bhavan.

Civic authorities have already shifted around 50 Covid-19 patients to Haj Bhavan. 

BBMP Commissioner B H Anil Kumar said on Thursday that due to an increase in the number of cases and due to shortage of beds in hospitals, the Haj Bhavan has been converted into CCC.

Headed by Rajendar Kumar Kataria, Secretary, Horticulture and Sericulture department, the CCC task force has arranged 400 beds at Haj Bhavan. 

“The facility at Haj Bhavan has already been made operational. Doctors, nurses, paramedical and house-keeping staff from BBMP have been deployed as per SOPs. All essential equipment, medicines and other facilities have been made available in adequate numbers at the Haj Bhavan,” Kataria explained.

In the second phase, the task force team has identified hostel rooms of seven engineering colleges, which would fetch about 3,200 beds to house asymptomatic Covid-19 patients. 

If need arises, the task team in the third and final phase, will consider the facilities such as Palace Grounds, Bengaluru International Exhibition Centre, Indoor Stadiums at Kanteerava and Koramangala to be converted as CCC.

Udupi, July 17: An Indian expatriate from coastal Karnataka who was working in Kuwait passed away in a hospital in the oil-rich country reportedly due to covid-19.

An ex athletic champion from Bhandarkars' Arts & Science College, he was a well-known Volleyball and Kabaddi player in Kundapur.  He was associated with many sports associations in Udupi. 

An employee of KRH firm, he was hospitalized in Kuwait three weeks ago due to ill health. He was tested positive for covid-19.

He breathed his last yesterday without responding to any treatment. Final rites were held in Kuwait. 

Prior to migrating to Kuwait, he had worked in United Arab Emirates for several years. A sports enthusiast, he had trained many athletes in Udupi.
