Temple priest arrested for killing 32-year-old woman, her daughter

New Delhi, Apr 25: Karnataka Medical Education Minister Dr K Sudhakar on Saturday said that a journalist from Bangalore Urban, who has tested positive for COVID-19, is one out of 15 new cases reported in the state.

He further said that out of the 15 new coronavirus cases, six each are from Bangalore Urban and Belagavi and one each from Mandya, Chikkaballapura and Dakshin Kannada. The state's tally is now 489.

"#COVID19 Update: From 5 pm, 24th April till 12 noon today. A total of 489 cases, 15 positives, 18 deaths & 183 discharges," Sudhakar tweeted.

India's total number of coronavirus positive cases has climbed to 24,506 including 18,668 active cases, 5,063 cured/discharged/migrated and 775 deaths, the Ministry of Health and Family Welfare said today.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Shivamogga, Feb 1: A three-year-old girl who fell out of a moving vehicle had a miraculous escape in Agumbe Ghat section in Teerthahalli taluk of Shivamogga district of Karnataka.

The incident took place in the early hours of Friday when 12 members from three different families were returning from a tour of Kerala and Tamil Nadu. The girl was reunited with her family after 30 minutes of high drama.

The child, identified as Anavi, is believed to have fallen from the vehicle as it negotiated hairpin bends on the Agumbe Ghat road, 350km from Bengaluru. The child's parents, Binu and Lincy, from NR Pura in Chikkamagaluru district, and other family members reportedly dozed off and did not realize the child had fallen off the vehicle until they covered a distance of about 20km.

One of the family members noticed that child was missing from the seat next to the door. When the driver realized the door latch had given way, they suspected the child could have slipped out of the vehicle.

Then the family started searching along the road and learnt from a forest guard at the Agumbe checkpost that a missing child was found and it had been handed over to Agumbe police station.

An advocate who identified himself as Vinay spotted the girl child as he passed the deserted stretch minutes after the vehicle left and picked her up and handed her over to Agumbe police.

The child sustained minor injuries in the fall. She was provided medical treatment before she was handed over to the parents.

Sources said it wasn't known how the vehicle door opened. One theory is that the girl could have accidentally unlocked the door while clutching the latch in the bumpy ride on the ghat. Police did not file any complaint.

Similar incident

This incident is almost a rerun of a Kerala incident in which a one-year-old baby fell off a moving jeep and was reunited with its mother hours later in September 2019 in Idukki district.

The baby had slipped off the mother's arms while she dozed off in the vehicle. CCTV footage showed the baby, after falling on the road, crawling towards a lit-up area close by, which turned out to be a forest checkpost. Family realised child was missing after 20km.
