Police check for passport may take just 8 days in future

Belagavi, 13: In a shocking development, Karnataka has reported its first COVID-19 relapse with a 50-year-old Tablighi Jamaat convention attendee in Belagavi testing positive days after being discharged.

The State health officials confirmed that P-298 from Kudachi, who had recovered and was discharged, has suffered a relapse. He has been re-admitted to a designated hospital in Belagavi.

The patient was initially admitted on April 15 and recovered, testing negative twice on April 30 and May 1. The tests were done at the National Institute of Virology (NIV), Bengaluru, and the National Institute of Traditional Medicine (NITM), Belagavi.

Despite recovering, his treatment continued in the ICU for other comorbidities, especially cardiac issues. He was discharged on May 4 and quarantined at an institutional facility in Kudachi.

However, he developed symptoms again and was tested for COVID-19 again on May 5 at NITM, Belagavi. The result came back positive. He was re-admitted to a hospital, and on May 6 a second test was done at the Belagavi Institute of Medical Sciences. Again, he tested positive.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Jun 30: Former Karnataka Chief Minister Siddaramaiah on Tuesday demanded setting up of an all-party committee to monitor treatment-related issues in hospitals and said there are allegations of "corruption and nepotism" in the management of COVID-19 treatment.

Siddaramaiah said in a tweet that Chief Minister BS Yeddyurappa should immediately form all-party monitoring committee.

"This is very much needed to increase public confidence in the backdrop of several complaints," he said.
"There are allegations of corruption and nepotism in the management of COVID-19 treatment. It is need of the hour to manage this unprecedented health crisis with public safety as the only objective," he said in another tweet.

He urged the Chief Minister to make the treatment protocol clear to the patients and instil hope. "Do not keep them in dark," he said.

The senior Congress leader also urged the Chief Minister to extend insurance and other benefits to private hospital doctors, nurses and support staff.
Karnataka has reported a total of 14,295 COVID-19 cases.
