Those dead include those with the history of Severe Acute Respiratory Infection (SARI), Influenza-like illness (ILI), inter-state and inter-district travel and cardiac patients.

The contact history of at least four dead people is under tracing.

Out of 1,694 positive cases on Friday, contacts of the majority of the cases are still under tracing.

Among the districts where the new cases were reported, Bengaluru Urban accounted for 994, followed by 97 from Ballari

and Dakshina Kannada, Kalaburagi 72, Tumakuru 57, Bengaluru Rural 44, Dharwad 38, Mysuru 35, Mandya 33, Bidar 28, Chamarajanagara 24, Shivamogga 23, Gadag 19, sixteen each from Udupi and Kodagu, Yadgir 14, thirteen each from Hassan and Belagavi, Kolar 11.

Bengaluru Urban district tops the list of positive cases, with a total of 7,173 infections, followed by Kalaburagi (1,560) and Udupi (1,258). Among discharges, Kalaburagi tops the list with 1,143 followed by Udupi (1,093) and Yadgir (855).

A total of 6,71,934 samples have been tested so far, out of which 18,307 were tested on Friday alone.

So far 6,35,582 samples have been reported as negative, and out of them 16,290 were reported negative on Friday.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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