Shia Muslims across Karnataka mourn martyrdom of Imam Hussain

Bengaluru, June 27: In the wake of mounting covid-19 cases across Karnataka, the state government has decided to extend the night curfew hours and to re-impose Sunday lockdown. 

Chief Minister BS Yediyurappa held an emergency meeting on Saturday with the state's top officials to discuss measures to further contain the spread of the novel coronavirus. 

During the meeting, it was decided that a state-wide lockdown will be imposed on each Sunday starting July 5. Only essential services and supplies will be allowed on Sundays.

Timings of the night curfew have also been revised to 8 PM - 5 AM from the earlier 9 PM - 5 AM. “We have decided to impose a curfew starting Monday, June 29, from 8 pm to 5 am every day. Right now, the curfew timing is 9 pm to 5 am, but it’ll be advanced by an hour to 8 pm,” said Home Minister Basavaraj Bommai

Commissioner of Bengaluru's civic body, BBMP has been directed to set up more wholesale vegetable markets to deter large crowds.

Meanwhile, government offices in Karnataka will open only five days a week and the weekend will be off for government employees.

It was also decided during the meeting on Saturday that a centralized bed-allocation system for Covid-19 patients will be taken up to ensure that each patient gets a bed without overwhelming the healthcare infrastructure.

Yediyurappa has also instructed officials to increase the number of ambulances for Covid-19 patients to 250 apart from arranging separate vehicles to carry mortal remains of victims. The police control room will aid officials in identifying the location and easing the movement of ambulances.

Information about nodal officers working for COVID management will be published. Joint Commissioners of 8 regions will be given additional responsibilities and KAS officers will be appointed to assist them.

The services of 180 ESI doctors appointed by the Labour Department will also be relied on by the state government. CM Yediyurappa has also asked officials to reserve wedding halls, hostels and other institutions in Bengaluru as COVID Care Centres.

Bengaluru Urban DC, on the other hand, was instructed to identify more places for the last rites of patients and also to form more teams for this purpose. 

The BBMP Commissioner has been told to notify reservation of 50 per cent beds in medical colleges and private hospitals.

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

Mangaluru, Apr 25: The coastal district of Dakshina Kannada today reported another covid-19 case. With this the total number of coronavirus positive case in the district rose to 18 including two deaths. 

The health and family welfare department in its bulletin today announced that a 33-year-old woman from Bantwal tested positive for coronavirus. She is undergoing treatment at Wenlock Hospital which is now converted into covid-19 hospital. 

She is the daughter of 67-year-old woman from Bantwal who was tested positive for the deadly disease last week. Both are the neighbours of the two women from Bantwal who died of covid-19 recently.
