Abu Dhabi: Bearys Welfare Forum hosts iftar get-together

Bengaluru, May 1: Karnataka Chief Minister BS Yediyurappa on Thursday announced Rs 30 lakhs compensation for corona warriors, in case they lose lives while carrying out their duties.

"Karnataka Chief Minister BS Yediyurappa has announced Rs 30 lakhs compensation for Anganwadi workers & assistants, civil workers, and police personnel who die after getting infected by COVID-19 while carrying out their duties," State Chief Minister's Office said in a statement.

According to Union Health Ministry website, a total of 557 cases of coronavirus have been reported in the state so far including 223 cured and 21 deaths.

Meanwhile, With 1,823 new cases of COVID-19 reported in the last 24 hours and 67 deaths, India's total count of coronavirus cases has gone up to 33,610, said the Union Ministry of Health and Family Welfare on Thursday.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jul 2: Former Karnataka Chief Minister HD Kumaraswamy on Thursday accused BS Yediyurappa-led state government of "failure" to protect the citizens from coronavirus, stating that Karnataka was suffering due to lack of co-ordination in the cabinet.

In a series of tweets, the JD(S) leader slammed the state government for wasting their time in giving out contradictory statements regarding COVID-19 figures instead of learning lessons from the Kerala government.

"It is shocking to see COVID-19 patients being turned down by the hospitals due to lack of beds. The government has failed in its duty to protect the citizens. The CM and his cabinet colleagues wasted precious time in mere talking for the last three months. As the escalated Covid numbers stare them in the face, they are now helpless," Kumaraswamy wrote.

"Even when you have a proven model in Kerala government's success in Covid management, the ministers waste time in issuing contradictory statements and doing nothing. Karnataka suffers due to lack of co-ordination in the cabinet," he said.

Urging the government to act together, he said that if the government does not get its act together, the day is not far when Covid patients would be "condemned to die on the streets."

We are already seeing heart-wrenching stories of patients denied treatment," he added.

Kumaraswamy also appealed to the Karnataka government to consider the suggestions he had made earlier and not to indulge in party politics in these testing times.

"I appeal to the government to consider the suggestions I made earlier and act accordingly. This is not the time for party politics."
