Kargil martyr's daughter gets 'rape threats' for opposing ABVP

Bengaluru, May 5: A 62-year-old woman from Vijayapura succumbed to coronavirus infection on Tuesday, taking the COVID-19 death toll in Karnataka to 28, a health official said.

The state has registered eight more COVID-19 cases in the past 19 hours, increasing the count of such cases to 659, the official added.

"Positive case 640, 62-year-old female resident of Vijayapura died on Tuesday due to cardiac arrest," the health official said.

Admitted to a designated hospital''s ICU on Sunday, the woman was also suffering from Chronic Obstructive Pulmonary Disease (COPD), Bronchial Asthma (BA) and complained of breathlessness.

Among the eight fresh cases that emerged in the state, four were contacts of earlier cases, two with Influenza Like Illness (ILI) and one with travel history to Uttarakhand.

The health department is also tracing the contact history of a 30-year-old woman from Bengaluru Urban.

Incidentally, no new cases emerged from Davangere as 22 cases rocked the district on Monday.

Among the new cases, Bengaluru Urban contributed 3, followed by Bagalkote, 2, Ballari, Dakshina Kannada and Bhatkal in Uttara Kannada, 1 each.

Mangaluru, June 16: A youth has been arrested by the sleuths of Ullal police station on charge of sexually assaulting a minor girl and impregnating her on the outskirts of the city. 

The arrested has been identified as Lavakumar alias Shravan, a resident of Valacchil, who was working in a fast-food outlet at Thokkottu. 

According to the police, the accused had sexually assaulted his owner’s minor daughter. The incident came to light when the girl’s mother came to know that former was pregnant.

It is said that the girl’s mother, who had employed the accused, allowed him to stay in their house. The accused befriended the minor girl and sexually used her.

Based on a complaint filed by the girl’s mother, a case was registered at Ullal police station under Pocso Act. The police arrested him yesterday and produced him before a local court.

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
