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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Apr 4: The Supreme Court on Friday urged Karnataka and Kerala to amicably resolve their issues concerning a border blockade that has choked the free flow of vehicles carrying essential items and patients in the midst of the COVID-19 outbreak.

Karnataka, which imposed the blockade, justified that its border was sealed to “combat the spread of the pandemic by preventing the movement of people from the bordering districts of Kerala to Karnataka”.

The State had moved the Supreme Court, challenging a Kerala High Court order on April 1 to open the border. Kerala has countered that patients from the State cannot be denied access to health care. Besides, the blockade has severely affected the supply of essential items, from medicines to food, to Kerala.

On Friday, a Supreme Court Bench of Justices L. Nageswara Rao and Deepak Gupta urged the States to not confront each other in the midst of an unprecedented public health crisis. Instead, it asked the Chief Secretaries of both States to sit with the Union Health Secretary and iron out a solution. Meanwhile, the apex court urged Kerala not to take any precipitative action based on the High Court order.

The court issued notice to Kerala on the appeal filed by Karnataka, represented by advocate Shubhranshu Padhi. It listed the case for further hearing on April 7.

Karnataka, in its appeal against the High Court order, said the blockade was put in place in the interest of public health. The situation regarding Coronavirus was “really dire”, it said. It warned that opening the blockade would cause a law and order issue as its local population wanted the border to remain sealed.

Karnataka argued that Kerala was the “worst-affected” State in the country with nearly 194 coronavirus cases. In this, Kasaragod, adjoining Karnataka, was the “worst affected” district of Kerala with over a 100 positive cases.

MP’s plea

The court also separately considered a writ petition by Kasaragod MP Rajmohan Unnithan for an order to forthwith open the State border.

The parliamentarian, represented by advocates Haris Beeran and Pallavi Pratap, urged the court to issue an ex-parte stay on the operation of the blockade imposed by Karnataka with its border States.

Mr. Unnithan said Karnataka’s blockade was “ill-planned and dangerous” and had led to loss of lives. Two patients from Kerala, in need of urgent medical care, died after their ambulances were denied entry at the border by the Karnataka authorities. 

Mangaluru, Jan 20: A suspicious unattended laptop bag with the suspicion of containing “something harmful” was found abandoned at the Mangaluru International Airport on Monday.

The bag, which was lying unattended near the entrance of the airport was removed from the spot by the airport security personnel at 8.45 am.

Bomb detection squad personnel has rushed to the spot and shifted the bag to a safe zone, said Mangaluru Commissioner of Police P S Harsha.
