Zakir Naik's IRF in HC against its immediate ban

Bengaluru, Mar 31: Persons under home quarantine are directed to send their selfies to the Karnataka government in every one hour, failing which they will be shifted to the state quarantine centres, said Medical Education Minister Dr K Sudhakar on Monday.

"All persons under home quarantine shall send their selfies to the government on a mobile application in every one hour. Failing to do so, teams will reach such defaulters and they will be liable to be shifted to quarantine centres made by the government," he said.

The home quarantine persons will be given an exception for taking selfies during the sleeping time from 10 pm to 7 am.

"There will be an exception in this order for sleeping time, from 10 pm to 7 am," he said.
The total number of COVID-19 cases in Karnataka climbed to 88 on Monday after five more persons tested positive for coronavirus.

Of the five, one is a close contact of an earlier confirmed patient and the others are workers of a pharmaceutical company in Mysuru, from where a person had tested positive, the state health department said.

The country is under a 21-day lockdown to prevent the spread of coronavirus, which according to the Ministry of Health and Family Welfare, has infected 1,251 people so far.

Bengaluru, Feb 18: A 26-year-old Kannada singer committed suicide over alleged dowry harassment on Monday. Sushmitha, a playback singer who got married to Sharath Kumar about one-and-a-half years ago, hung herself from the ceiling at her parent's home in Nagarabhavi, Bengaluru on Monday.

The singer sent a Whatsapp to her brother and mother before hanging herself early morning on Monday. She accused her husband and his relatives of dowry harassment in her death note.

According to Bengaluru Police, the singer has accused her husband, his sister and his aunt of harassing her for dowry in her death note. On Monday morning, Sushmitha's brother alerted the police after he found her dead body hanging from the ceiling. She used her dupatta to hang herself.

Sushmitha had lent her voice for Kannada songs in films like Haalu Thuppa and Srisamanya.

Police informed that Sushmitha sent a Whatsapp message to her brother, Sachin, at around 1 am on Sunday and explained that her husband Sharath and her relatives have been harassing her since the time she got married. Sachin read the message at around 5:30am and rushed to her room where he found her hanging from the ceiling.

In the text message, Sushmitha wrote that her husband, Sharath, his sister, Geetha, and his aunt, Vydehi, harassed her and they were the reason behind her ending her life. She also stated that she did not want to end her life in their house and hence came to her parents’ house.

The Annapoorneshwari Nagar police have registered a case of dowry death, charging her husband and his sister and aunt based on complaint filed by Sushmitha’s mother Meenakshi. The three accused are on run after hearing about her death and police said that efforts are on to trace them.

Sushmitha's husband Sharath Kumar is a manager in a car showroom and a resident of KS Nagar in Bengaluru.

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
