Bengaluru, Apr 4: The state government have taken all measures to ensure availability of essential supplies including foodgrains, in the state, Chief Minister B S Yediyurappa informed here on Saturday.

He was speaking to newsmen, after holding a meeting of the MLAs, MPs and others, where he had briefed over the measures taken by the state government to prevent the spread of the COVID-19 disease.

Bengaluru, Mar 23: Karnataka Health Minister B Sriramalu on Monday confirmed that there are 27 positive coronavirus cases in the state so far.

A fresh COVID-19 positive case has been reported from Mysore today.

"One hospital in every district is dedicated to COVID-19 treatment. We have placed an order for 1000 ventilators. We have also ordered 10 lakh N90 mask, five lakh PPE testing kits, 15 lakh three-layer masks. Sanitizers and thermal scanners will also be purchased on-demand," said Sriramalu while addressing a press conference here.

The Karnataka Health Minister said that decision will also be taken to purchase lab testing kits and equipment.

Meanwhile, Dr Ashwath Marayan, Deputy Chief Minister, Karnataka said that all necessary measures are being taken to contain the spread of COVID-19.

"We will take important decisions as soon as possible. 80 per cent of the companies are following work from home. Critical and essential things should be provided in this situation and we have kept them available to serve the people," said Marayan.

"We have taken all the required decisions including the logistics and supply. Social distancing is much important and we will implement it," he added.

The total number of positive coronavirus cases in the country mounts at 415, according to the Indian Council of Medical Research (ICMR).

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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