Mangaluru, Mar 4: Fifteen Iranian fishermen, arrested for illegally entering Indian waters, were shifted from Mangaluru to Central Prison Bengaluru at Parappana Agrahara recently.

 On October 21, coast guard officials intercepted two fishing vessels near Gayathri island, about 168 nautical miles off Mangaluru Coast and took into custody 15 crew members after they failed to produce necessary documents.

While one of the boats capsized after developing a technical snag, the other boat was brought to Mangalore Port.

On the basis of a written complaint lodged by Indian Coast Guard (ICG) Deputy Commandant Kuldeep Sharma, Karnataka State Coastal Security Police (KSCP) station in Mangaluru filed case against the 15 Iranian fishermen under Maritime Zone of Indian Act 1981.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mysuru, Mar 7: Karnataka Minister for Medical Education K Sudhakar on Saturday said that State Government may consider suspending the touch-based Biometric time and Attendance system for its employees in view of the COVID-19 threat.

Speaking to media persons while inspecting the medical infrastructure at KR Hospital here on Saturday, he said that many IT companies have already suspended the Biometric Attendance system in a bid to prevent the spread of the virus. Given the threat perception, the government was also contemplating the same and would consider it. However, he did not specify the date.

With regard to the preparedness to handle the threat, the Minister said the government was extremely cautious since last 20 days and had taken all precautionary measures. “All international passengers at the airport are being screened and so far nearly 1 lakh passengers have been screened and anyone with symptoms will be quarantined for 28 days.’’
