Mosques in Karnataka lead fight against Corona; caution through loudspeakers four times a day

Belgaum, Jan 1: Police detained a group of around eight people who were allegedly trying to hoist 'Uttara Karnataka flag' in Hire Bagewadi area here on Wednesday.

This comes amid tensions between Karnataka and neighbouring Maharashtra over the border issue with protests on both sides, which have also led to the cancellation of bus services between the two states.

Protesters in Belagavi burnt an effigy of Maharashtra Chief Minister Uddhav Thackeray, following which Shiv Sena workers had launched a protest near the Kolhapur bus stand on Sunday, and burnt an effigy of Karnataka Chief Minister BS Yediyurappa.

The long-standing border dispute between the two states over is pending before the Supreme Court for several years.

On December 7, Thackeray had chaired a high-level meeting over the border dispute between two states. It was decided in the meeting that attempts will be made to get fast track hearing in Supreme Court on the issue.

Bengaluru, May 9: With 41 new cases of COVID-19 reported on Saturday, the total number of positive cases in Karnataka has reached 794, said the state Health Department.

Out of the total number, 386 are discharged and 30 patients have passed away. The total number of active cases now in Karnataka is 377.

The total number of positive coronavirus cases across the country is 59,662, including 39,834 active cases.

Till now, 17,846 patients have been cured and discharged and 1,981 deaths have been recorded in the country, as per the data provided by the Union Ministry of Health and Family Welfare. 

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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
