Former BJP minister hits out at Anant Kumar Hegde, calls him a ‘useless loafer’

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 22: Areas having three to four COVID-19 cases being termed as clusters will be totally sealed and maximum testing will be conducted there, moreover only critical cases will be shifted to COVID hospitals in Bengaluru, said Karnataka Home Minister Basavaraj Bommai.

Speaking to media persons, Karnataka Home Minister Basavaraj Bommai said, "It has been decided that clusters (areas having 3-4 #COVID19 cases) will be totally sealed and maximum testing will be done there. Only critical cases will be shifted to Covid hospitals. I demanded that police personnel are tested on priority."

"A lot of issues were discussed about the spike in COVID-19 cases. As far as hospitals are concerned there are two types of patients, asymptomatic and symptomatic, moderate and critical. Moderate and normal cases can be shifted to COVID centres," he added.

Bommai further added that beds in hospitals need to be reserved for corona warriors as well.

"There has to be a coordination between BBPM who brings the patient and the hospital, the moment a positive case is reported to avoid the waiting period. Even in hospitals, some beds have to be reserved for corona warriors. Community transmission is not yet there but we have to be prepared," he added.

Earlier today, Karnataka Chief Minister BS Yediyurappa had called an emergency meeting of concerned officials and departments to discuss measures to control rising COVID19 cases in Bengaluru.

As the numbers of COVID-19 cases are increasing in Bengaluru at an alarming rate, the Chief Minister opined that this can be contained only if preventive measures were implemented strictly.

He directed the officials to implement lockdown strictly in the clusters, which reported more number of cases, especially KR Market and surrounding areas such as Siddapura, VV Puram, Kalasipalya. It was decided to seal the adjoining streets, where the cases are reported.

He said that stringent action would be taken against those who violate quarantine and FIR would be filed if necessary.

Officers were directed to fix rates for treatment of COVID patients in private hospitals to make coronavirus treatment accessible to all.

Yediyurappa further instructed officials to set up fever clinics in all wards and maintain hygiene and provide other basic amenities to the people who were quarantined in social welfare hostels and other government institutions.

"COVID-19 should be contained without affecting the economic activities in Bengaluru, which resumed recently," he said.

"COVID War Room shall have real-time information on the availability of beds in various COVID hospitals and shall facilitate the infected person to avail treatment without losing any time," added Yediyurappa.

Udupi, July 20: A youth, who was under depression after his business came to a halt due to lockdown, has killed self in Kundapura taluk of Udupi district.
