Circle Inspector shoots himself to death in police station

Belthangady, May 15: Carcases of more than 50 monkeys were found at Bandaru gram panchayat in the taluka here on Friday.

The carcasses were found on the Kundalapalke-Padmunja road in Bandar village. Locals had seen the monkeys’ carcasses night of Thursday and informed authorities about it.

Kaniyuru Health Centre’s medical assistant Swatantra Rao and Ujire health Centre’s Medical Officer, Forest Department staff, veterinarians and local Panchayat officials visited the spot.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, Jun 23: An elderly person, who was undergoing treatment for covid-19 in Mangaluru, breathed his last on today. 

The victim, identified by number P-6282, was a 70-year-old man. He had returned from Bengaluru on June 7. 

He was suffering asthma and pneumonia. He had Severe Acute Respiratory Infection (SARI) symptoms and was hence admitted to the designated covid-19 hospital in Mangaluru on June 12. 

His condition continued to worsen and today he breathed his last, sources said.

With this the total number the deaths of covid-19 patients in Dakshina Kannada district mounted to 9.
