‘Celebrating murder’: BJP hits out at Prakash Raj for criticising PM’s chilling silence

Bengaluru, May 10: Karnataka on Sunday reported 59 new cases of coronavirus, taking the total number of cases in the state to 848, informed state health department.
Out of the total number of cases, 422 people have been discharged and 31 have died due to the infection in the state.
The health department further informed that six COVID-19 patients are currently in the Intensive Care Unit.

Jun 19: BJP leader Devendra Fadnavis on Thursday said Maharashtra Chief Minister Uddhav Thackeray should sign an agreement with neighbouring Karnataka to avoid a repeat of flood in part of the state like it happened in August last year.

In August 2019, Kolhapur, Sangli districts and some other parts of the state faced unprecedented floods triggered by huge release of water from dams in western Maharashtra and from the Almatti dam in Karnataka.

Fadnavis said, The Maharashtra chief minister should hold an urgent meeting with the Karnataka chief minister and enter into an agreement over-discharge of water from the Almatti dam located on the border of both the states."

If water is not released from the Almatti dam in time, it will cause flooding in border areas of Maharashtra such as Kolhapur and Sangli.

"A pact between the two states would benefit both as it would help in keeping water levels in control, the former chief minister said.

The dams in the state already have sizeable water stock. It would be better if the chief minster schedules a meeting with the Karnataka chief minister regarding the same (agreement), the Leader of Opposition in the assembly 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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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
