Mangaluru/Udupi, Jun 7: Coastal districts of Dakshina Kannada and Udupi have recorded 17 and 13 new coronavirus positive cases between 5 p.m. on June 6 and 5 p.m. on June 7. 

16 among 17 new covid patients in Dakshina Kannada are returnees from Maharashtra, while one returned from Goa recently.

Maharashtra returnees comprise 14 males, including three teenagers t, and two females aged 32 and 41. The Goa returnee is a 32-year-old male.

All of them have all been admitted to the designated COVID hospital in the district.

With this, the total tally of coronavirus cases in Dakshina Kannada has risen to 203, out of which 47 are currently active. As many as 150 patients have recovered and been discharged, and seven have died.

Among the 13 in Udupi, 12 are Maharashtra returnees, while process of contact tracing of one patient, a 30-year-old woman, is going on.

The patients comprise eight males, including a 7-year-old boy, and five females. They have all been admitted to the designated hospital.

This takes the total number of coronavirus cases in Udupi district to 902, out of which 798 are currently active, 103 discharged, and one patient has died.

Bengaluru, Jun 20: A petition has been filed in Karnataka High Court to transfer Amulya Leona case to the National Investigation Agency (NIA). She raised pro-Pakistan slogans at an anti-CAA rally on February 20 at Freedom Park.

The petition, filed by advocate Vishal Raghu, blamed the probe team for not filing chargesheet on time and suggested the state government to approach the higher court against bail granted to Amulya Leona.

On June 11, she was granted conditional bail by the Bengaluru civil court.

She was charged with sedition for her actions in the presence of All India Majlis-e-Ittehad-ul-Muslimeen chief Asaduddin Owaisi.

The court granted bail after hearing the bail application. Amulya's advocate on behalf of the petitioner said, "the petitioner is just a 19-year-old lady and she is studying in a private college in the Bengaluru. She shouted 'Pakistan Zindabad' but she never mentioned Pakistan as her country."

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
