Udupi, Feb 10: The throat swabs of three suspected coronavirus patients in Udupi that was sent for tests have come back as negative.

Throat swabs of three persons who got admitted at a district government hospital in Udupi with symptoms of fever on Friday was sent to Bangalore medical college and research institute for test to know whether the admitted persons who returned from China 15 days back had contracted coronavirus.

The 30-year-old man from Kaup taluk had been China on personal work and had returned to Udupi 15 days back. Upon showing the symptoms of fever, throat pain and cold, he was suggested to get admitted.

He was admitted in the isolation ward and was directed to remain under quarantine till the observation period ends and till the test report is obtained.

Another family from Mandarthi, a man and his wife, who had returned after a tour from China 15 days back were also kept under observation at the isolation ward in the district government hospital, Udupi.

Udupi DC G Jagadish has said that there are no coronavirus case reported in Udupi and people need not panic. Sources said that the three tested negatives for coronavirus in Udupi will be discharged from the hospital on Monday.

Bengaluru, Feb 5: New Tulu movie Pingara has bagged the NETPAC International Jury Award at the 12th edition of Bengaluru International Film Festial (BIFFes) on Wednesday.

Written and directed by Preetham R Shetty, the movie revolves around people who worship daivas (spirits) of Tulu Nadu.

The narrative goes back and forth in time, to tell the story of a family to Sinchana (Chaitanya Chandramohan), a journalist from Bengaluru who visits a village in Tulu Nadu to ‘write on Tulu culture.’

The film speaks about the caste system in Tulu Nadu and the struggle for land in the post-independence period.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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