Bidriware demo by Qadri enthralls students of Alevoor school

Bengaluru, Jul 4: Amid the rising COVID-19 cases in the state, the Karnataka COVID-19 Task Force has decided to set up booth-level committees across the state including 8,800 here for effective monitoring and surveillance.

The task force also released detailed guidelines for home isolation for asymptomatic cases including 17 days ''home isolation'' for patients below 50 years of age. It also warned of legal action against those health workers for disrespect to the bodies.

Briefing reporters after the meeting on Friday, Medical Education Minister Dr K Sudhakar said the local management will be strengthened for effective monitoring and surveillance of COVID-19 cases. "There will be booth-level task force committees throughout the state right from the village to Bengaluru.

These task force committees will act at the ultra local level. The task force will act as a structural and functional unit of COVID-19 dealing with monitoring, surveillance, checking of all the ILI cases, ambulances and hospitals," he added.

He also said the committees will comprise one member each from the Health department, police department, municipalities or Panchayat, volunteers, valveman. The committee will have five to six members.

The principal secretary in the Village Development and Panchayat Raj department L K Ateeq has been appointed as the nodal officer to manage the task force in the rural areas whereas in the urban areas, the Urban Development secretary, the municipal administration directors and the municipal commissioner will form the local task force.

"In Bengaluru alone 8,800 teams will be formed, which will be coterminous with the 8,800 booths in the city. They will provide the real-time data. They will be imparted training," the minister added. Noting that there were about 8,800 electoral booths in Bengaluru city and each booth will have a task force committee, he said a nodal officer has been appointed to oversee this.

The state level task force also came out with a slew of conditions. As far as home isolation is concerned, it would apply for patients who are below 50 years and have no symptoms of any other disease, and their homes should have a toilet and have an attendant.

He also said home isolation duration has been increased from 14 to 17 days. "People should not get fever in the next three days after completing 14 days, else they will be quarantined for another seven days. If they don''t get fever then they will be freed to perform their personal activities," Sudhakar said.

Those who are above 50 years and have comorbidities, will be treated at the COVID care centres only and they will be under medical supervision and be subjected to regular tests. The state is also making arrangements for telecommunication for those who are asymptomatic but wish to speak to a doctor.

It was also decided to have at least two ambulances in each of the 198 wards of Bengaluru. The minister said the additional commissioner of police (traffic) will be the nodal officer to coordinate the movement of ambulances. The task force has also appointed a nodal officer to manage the hospitals based on the availability of beds and ventilators. The officer will provide real time information about beds.

"We want to make sure that no one has to run from one hospital to another," Sudhakar said. On the cremation of the bodies, Sudhakar said guidelines have been issued on how to handle bodies at mortuaries, taking them in the ambulances, human treatment to the deceased while performing the last rites and fumigation of the bed. "Legal action will be taken against those who treat bodies in an inhuman way," Sudhakar said.

The state-level task force has also decided to arrange for test reports within 24 hours. It has also been decided to increase the testing capacity from the existing 15,000 a day to 25,000. In view of the spurt in COVID-19 cases, the task force also recommended antigen tests in crowded areas to check whether there was community spread.

To a question on closing down the border, the minister said there is no question of lockdown. "We cannot hide from this disease. It is not a solution. We have to live with it now, yet maintain a distance from it," he added. Sudhakar, who is a doctor himself, said COVID-19 is not as deadly a virus as those he had seen in the past and asked people not to be scared of it.

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 , Mar 21: Karnataka Congress President DK Shivakumar exuded confidence that the party will return to power in the state and praised former chief minister Siddaramaiah's term.

"I am confident that we will come back to power. Everyone in the past has worked their best to build the party. Siddaramaiah being a full-term chief minister gave the best programs to Karnataka, his government's programs were the best of all time," Shivakumar said at a press conference on Friday.

He further assured his full support to anyone who wanted to work for the betterment of the party.

"Though I have become the state president of the party but I am still the worker of Congress and each of us should work for the party as ground workers.
