Madikai Kammaran, who strengthened BJP in Kasaragod region, is no more

Bengaluru, Mar 2: Killing an Indian porcupine and inviting his TikTok followers to view it proved costly for a 25-year-old man from Kalaburagi. Forest department officials tracked him down and arrested him on Sunday morning.

Manjunath Biryalhissa, a resident of Jewargi taluk, was famous for his various TikTok videos and for lifting heavy stones in his village and neighbouring areas.

According to forest officials, on Friday, Manjunath and his friends caught a porcupine in Sindagi range, Vijayapura and stoned it to death. Later, they fried and cooked it. Manjunath then made an 18-second video, where he spoke about the porcupine hunt and slaughter, besides inviting his followers to like the video and join him in the feast.

The video was on TikTok and Facebook. Wildlife activists who found the video alerted forest department officials.

“Porcupine comes under schedule four of the Wildlife Protection Act, 1972. Keeping this video as evidence we were able to trace him through his Facebook account, where he had shared details of his hometown,” said forest officials.

Mangaluru, Mar 9: Deputy Commissioner Dakshina Kannada, Sindhu B Rupesh on Monday refuted reports that a passenger who arrived in Mangaluru from Dubai showed coronavirus symptoms had skipped a hospital visit.

While replying to reporters on the issue, Rupesh said: "Passenger who arrived from Dubai has not shown any coronavirus related symptoms. He just had a fever. He was shifted to district hospital last night, but he is not cooperating with us. He is not ready to stay in a hospital. We are convincing him".

"Till now, no positive case of coronavirus has been found in Mangaluru", she added.

Earlier, the Centre had suspended visas and e-visas granted on or before March 3 to people travelling from Italy, Iran, South Korea, and Japan, effective immediately, after a surge in cases of COVID-19 in these countries.

The coronavirus has affected 43 people in India so far and caused the deaths of over 3,800 people globally.

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
