Mangaluru, Jul 22: Institute of Medical Sciences and Research Centre, within the metropolis, has obtained approval from the Indian Council of Medical Research (ICMR) for testing SARS-CoV-2 virus by Real Time RT-PCR technique.

This has given a lift to the prevailing Covid-19 testing services in Dakshina Kannada, according to a press release by the AJ Institute here on Wednesday.

Institute Dean stated that devoted kiosk for pattern assortment has been opened in the hospital. Staff and technicians from the Department of Microbiology have undergone coaching in molecular testing at NIMHANS, Bengaluru.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Apr 30: Karnataka has decided to allow all industries located outside COVID-19 containment zones to operate from May 4, Chief Minister BS Yediyurappa said Thursday, even as he cautioned that the coronavirus crisis may last another couple of months.

“We feel that the COVID-19 menace is reducing and coming under control in the state. In Bengaluru, not many cases have been reported in the last 3-4 days. If this continues, it’ll help us open up industries in and around Bengaluru also. We’ll wait for another 2-3 days,” Yediyurappa told reporters after chairing a meeting of the Cabinet.

Yediyurappa and Industries Minister Jagadish Shettar are scheduled to meet industry captains on Thursday evening to discuss resuming operations from May 4.

"It won't be a surprise if the corona continues for another 2-3 months. However, based on Prime Minister Narendra Modi's directions, stringent lockdown measures (at red zones) and reviving economic activity will go hand in hand," Yediyurappa said.

The Cabinet decided to allow one-time inter-state or inter-district movement of people and labourers stranded due to the Covid-19 lockdown. The move will also benefit students and others who want to return to their native states or districts.

The government will also allow people from Karnataka residing in other states to return only if they are tested negative for Covid-19, Law Minister JC Madhuswamy said. An official order for this will be issued by evening today.

"Expenses should be covered by those wishing to travel. The government is willing to arrange buses for their benefit," Madhuswamy said. The government will provide a license to anyone who wishes to go, he said.

Having relaxed norms for industries outside red zones to resume operations, Madhuswamy said that inter-district passes will be issued to the top management of these units to travel from their homes to workplaces.

Liquor outlets, saloons and restaurants will remain closed till May 3, after which the government will take a call based on directions issued by the Centre.

“Opening of malls and hotels is not an option before us right now. But all hotels can give parcels,” Yediyurappa said. “I’m confident that the PM will allow the resumption of all activities.

He has already said that corona (containment) and economic activities will have to go hand in hand. So, I’m expecting the Centre to make some favourable decisions,” he added.
