Karnataka HM: Gauri Lankesh killers will be caught in a few weeks

Kasaragod, Apr 6: Even as the number of positive cases of Novel Coronovirus is on increase in this district, the ten-member medical team from Thiruvananthapuram on Monday will inspect and review modalities to convert the proposed Kasaragod medical college into a COVID-19 hospital.

Given the constraints being faced by the district hospital in Kanhangad near here, the 200-beded Kasaragod medical college hospital in Ukkinada near here would be equipped to cater to the Covid-19 patients on isolation.

The ten member medical experts who reached here late on Sunday, are on a special mission to immediately equip the hospital as to convert it as a Covid-19 centre.

Kundapur, Apr 10: Police have lodged a case against Nagaraj Mogaveera, 28, a resident of Karwadi Saukur in Kundapur, for sharing a communal hatred and sensitive post over Facebook.

On his Facebook page, he wrote, "1,500 persons went to Delhi mosque from Karnataka. Each person's test costs Rs 4,500 which becomes expenditure of Rs 67,50,000 in all. If they be encountered, each bullet costs Rs. 63 and the total expenditure will be Rs 94,500."

According to the complaint filed by Mukhtar Ahmad of the Janata Colony of Kundapur Karwadi village on Friday, the police have booked a case under the IPC Section 1860, 295A, 505 (2) and launched the investigation.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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