Udupi, Feb 5: A school boy died after being bitten by a venomous snake while he was returning home from a playground at Perdoor village in Udupi district.

The victim has been identified as Abhinav (9), son of Raju Shetty and Gita Shetty couple from the same village. 

Abhinav had returned from school yesterday evening as usually. He then went out to play. At around 7 p.m. while he was walking towards home, a snake bit him sources said. 

He was immediately taken to KMC Hospital in Manipal, where doctors pronounced him brought dead. 

A case of unnatural death has been registered in the jurisdictional police station.

Chikkamagaluru, Mar 8: A 20 member armed gang barged into a farmhouse at Gudde Thota near Jayapura in Koppa taluk and looted valuables and cash worth about Rs 12 lakh after assaulting the inmates, Police said on Sunday.

According to police, the culprits covered their face with masks and after assaulting watchman they broke open the main door and tied up Vijayaraghav and his wife Asha before robbing the valuables.

The culprits took away Rs 2.5 lakh in cash and valuables worth over Rs 10 lakh.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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