Karnataka’s list of 30 ignored; Good news for SL Bhyrappa, 10 others

Bengaluru, Mar 29: There was no shortage of masks and testing kits for detecting coronavirus cases in Karnataka and the government would import them if a need arose, Chief Minister B S Yediyurappa on Sunday said.

Apprising leaders of political parties on measures taken by his government to combat spread of coronavirus, he also told an all-party meeting that the government has decided to provide life insurance cover to police and civil workers and has taken extra precautions to maintain supply of food grains.

"There is no shortage of testing kits, medicines and masks. If there is need, we will import more... We will distribute testing kits to all the district and Taluk hospitals," he was quoted as saying in a government release.

The state has so far reported 76 COVID-19 cases including three deaths and five discharges.

At the meeting held in the Vidhana Soudha here, former chief minister and senior Congress leader Siddaramaiah said there were shortcomings in the screening of passengers coming from abroad and stressed on the need to maintain supply of essentials.

Yediyurappa said supply of foodgrains would be made through Public Distribution System and the government had taken extra precautions to avoiod any difficulties.

He told the leaders that there was no restriction on agriculture activities in the state.

"I have been regularly holding meetings since March 13 regarding the measures taken to contain the transmission of COVID-19," the chief minister said.

Health Minister B Sriramulu, Medical Education Minister Dr K Sudhakar, IT-BT Minister C N Aswath Narayan, Deputy Chief Minister Laxman Savadi, Siddaramaiah, JD(S) MLAs H D Revanna, D K Shivakumar and former speaker K R Ramesh Kumar attended the meeting.

Yediyurappa said a task force comprising of ministers and officials has been formed to oversee the implementation of the government orders in view of the 21-day lockdown.

He highlighted the prevailing situation across the globe saying normal life has been paralysed everywhere.

The chief minister also brifed the leaders about the number of clinics all over the state, availability of medicines and protection gear for the doctors and in quarantine rooms in the state.

Flagging concerns over screening process, Siddaramaiah said around 4,500 people were yet to be tracked, which need to be taken up on a warfooting.

"The government is saying that we have not reached the third stage but in Nanjangud, a person contracted the disease though he does not have any travel history. This must be probed," he said.

The former former chief minister asked the government to make sure that the free distribution of food grains to weaker sections take place without any difficulty from April 1, as announced by the Central government.

He objected to police 'excesses' while enforcing lockdown.

Siddaramaiah also asked government to bring the police personnel under special insurance cover.

Udupi, Mar 11: An elderly woman, who had recently visited Saudi Arabia has been admitted to an isolation ward at KMC in Manipal, here with symptoms of fever, cough and breathlessness.

The 68-year-old woman hails from Sagar taluk in Shivamogga district of Karnataka.

The patient had travelled to Saudi Arabia in the last week of February and was treated for fever cough and breathlessness there.

After recovery, she had travelled back to Bengaluru, where she was screened at the airport. 

Later, she reached Shivamogga where she was treated at Nanjappa Hospital for symptoms of fever, cough. 

As she has symptoms of coronavirus, she is quarantined and is under observation. The samples will have been sent to Bengaluru and the result is awaited.

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
