Bengaluru, Jun 15: A total of over 4,000 COVID patients have been discharged in Karnataka so far, as the state on Monday reported 213 new cases of coronavirus and two related fatalities, taking the total number of infections to 7,213 and the death toll to 88.

On Monday alone 180 patients were discharged in the state after recovery. As of June 15 evening, cumulatively 7,213 COVID-19 positive cases have been confirmed in the state, which includes 88 deaths and 4,135 discharges, the health department said in its bulletin.

Out of the 2,987 active cases, 2,931 patients are in isolation at designated hospitals and are stable, while 56 are in Intensive Care Units. Among the two deaths were a 65-year-old man from Dharwad, who was the contact of another patient already tested positive.

He was admitted on June 14 at a designated hospital and died the same day. The other was a 75-year-old woman from Bengaluru, diagnosed with ILI (Influenza Like Illness) A known case of Diabetes mellitus and Hypertension , she was admitted on June 13 at a designated hospital and died on June 15.

Out of 213 new cases 103 are returnees from other states, a majority of them from neighbouring Maharashtra, while 23 are those who returned from other countries.

Among the districts where the new cases were reported, Kalaburagi accounted for 48, followed by Bengaluru urban 35, Dharwad 34, Dakshina Kannada 23, Raichur 18, Yadgir 13, Bidar 11, Ballari 10, Koppal 4, three each from Vijayapura, Bagalkote and Shivamogga, two each from Udupi, Haveri and Ramanagara, and one each from Hassan and Davangere.

Udupi district tops the list of positive cases with a total of 1,028 infections, followed by Kalaburagi 944 and Yadgir 822.

Among discharges also Udupi is on top with total of 736 discharges, followed by Kalaburagi 459 and Bengaluru urban 329. A total of 4,49,331 samples have been tested so far, out of which 5,362 were tested on Monday alone.

So far 4,32,346 samples have been reported as negative, out of which 4,738 reported negative today, the bulletin said.

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

Kottayam, Mar 31: A 91-year-old and 88-year-old senior citizen couple were discharged from the isolation ward of government medical college after getting treated from COVID-19 on Monday.

"It is a testimony to the dedication and expertise of the medical staff as well as the strength of the Kerala public health system. We shall overcome," Kerala Finance Minister Thomas Issac tweeted as he praised the healthcare services for treating the elderly couple considered as highly vulnerable to the contagious virus.

Apart from the two senior citizens, five others suffering from COVID-19 have also been treated and discharged from the hospital.
Thomas, 91, and his wife Mariyamma, 88, who were under treatment at the Kottayam Medical College were already suffering from various age-related problems. The 91-year-old had a heart attack and severe breathing trouble when he was under treatment.

"The aged couple based in Ranni in Pathanamthitta district had got infected with the virus after coming into contact with their son, wife and grandson who had arrived from Italy. COVID-19 was confirmed in them on March 8. They were admitted to Pathanamthitta hospital. However, they were shifted to the Medical College in Kottayam the very next day as their condition was critical," the Kerala government said.

The family will have to remain in home-quarantine for 14 more days.

The Union Health Ministry said the death toll due to COVID-19 has risen to 32 and the number of total coronavirus cases to 1,251 as on Monday. 

There are 1117 active cases in the country with the state of Kerala contributing the highest number of cases which stands at 202.
