Police constable assaults top official of Belagavi airport

Bengaluru, Apr 24: Karnataka Chief Minister BS Yediyurappa on Thursday held a meeting with state officials to address the situation in the wake of COVID-19 pandemic.

Due to COVID-19, the prices of the crops have come down. It was instructed to buy those vegetables and keep them in cold storage and then sell. It was also instructed to export fruits, vegetables which cannot be kept for a long time to other states and countries.

Wherever there is a scarcity of drinking water, it was decided to supply water immediately.
Chief Minister Yediyurappa had earlier spoken to Union Minister Sadananda Gowda and took information regarding fertilisers.

As fertilisers' demand is less in the international market, the Union minister for fertilisers said that farmers will be given fertilisers at less than the actual price.

As some of the associations/guilds have violated the lease conditions by not starting the actual work which they have got the land for in Bengaluru, they have been instructed to return the land to the government where the lease conditions have been violated.

As far as the irrigation department is concerned, much water is stored in dams. It was decided to utilise the same for the cultivation of crops and for the purpose of drinking.

As far as the education department is concerned, it was instructed to give online training to students.

With the help of state television channel Doordarshan, it has been decided to teach students about the syllabus and other activities till the reopening of school.

The KSRTC has lost hundreds of crore due to the reduction in bus services due to COVID-19. So, they were instructed to use buses to transport goods to generate revenue.

The government also decided that salary for the doctors, who are working on a contract basis against COVID-19, will be increased significantly.

Bengaluru, May 8: 45 more COVID-19 cases have been reported from Karnataka, taking the total number of coronavirus cases in the state to 750, the state Health Department said on Friday.

According to the Health Department, the total cases include 371 discharged cases and 30 deaths.

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
