IFF deploys 1,200 volunteers in holy sites to serve Hajj pilgrims from India

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Kota, May 9: Karnataka Yakshagana Academy has come to the rescue of artists in distress due to cancellation of all Yakshagana festivals following coronavirus outbreak and clamping of lock-down.

The academy spends lakh of rupees every year from the money sanctioned to it on training new artists, performances and documentation. However, no such activity was undertaken due to COVID-19. Hence, the academy is discussing to transfer a large amount of money to Yakshagana artists as emergency aid, Academy President Prof M A Hegde said here.

In a statement issued here on Saturday, he said that along with this aid the donations by the public and Yakshagana admirers too could be given to the artists.

Mangaluru, Jan 5: In a frightening incident, a leopard which was trapped in a snare attacked and injured three persons in its successful bid to escape Balpa village in Sullia taluk of Dakshina Kannada. 

The incident occurred on Thursday when around 15 forest staff approached the trapped leopard to tranquilize it with a dart. The leopard, however, managed escape. 

While running away, it attacked a villager Balakrishna, aged about 70, who was working in the nearby plantation. He sustained injuries on his upper lips.

He was rushed to a hospital in Sullia and then was shifted to the Government Wenlock hospital for further treatment. He is learnt to be out of danger.

After this incident, the forest department kept a tab and tracked the leopard using a drone.  

According to V Karikalan, deputy conservator of forest (DCF), Dakshina Kannada, Between 5pm to 5.30pm on a tip off that leopard was spotted near a bush, the forest department tried to approach it again and the animal jumped on the officials, injuring Assistant Conservator of Forests Austin and forest guard Divith. 

The injured were rushed to a nearby hospital and then taken to Mangaluru for further treatment. They are learnt to be out of danger.

Meanwhile, the department is continuing combing in the village and surrounding areas. Three teams consisting of three RFOs and 10 Dy RFOs, supported by doctors are on the field. The forest department has also placed two leopard capturing cages in the area. Night patrolling will continue and public announcements are being made.
