Mangaluru: Minister Khader rescues Sabarimala devotees from burning car

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru: The Karnataka-Kerala border closure at Talapady amidst nationwide Covid-19 lockdown has not only prevented the movement of vehicles and people from Kasaragod to Mangaluru but also stopped the supply of life-saving drugs from Karnataka’s medical hub to its bordering district.

Hundreds of people from Kasaragod and Kannur districts who were treated in hospitals of Mangaluru for past several years are still dependent on some of the medicines that are available only in Mangaluru. Such medicines have become inaccessible for Keralites following the border closure. Every day, a number of people from Kerala call their acquaintances in Mangaluru to see if there is a way to get medicine.

In fact, Karnataka government has blocked all 23 roads that connect the state with Kerala. The reason given was, Kasaragod is the hotbed of coronavirus and allowing traffic even in emergency cases might lead to spread of Covid-19 in border districts of Dakshina Kannada, Kodagu and Mysuru. The attitude has resulted in the death of around a dozen people in Kasaragod district in last couple of weeks.

Even after the intervention of the Supreme Court a few days ago, the authorities in Karnataka are facing the allegation of being hostile either by blocking the way ahead or turning a deaf ear to the patients reaching their border. 

At this juncture, three Good Samaritans – P K G Anoop Kumar of Canara Engineering College, Mangaluru, Satheesh Shetty of Kasaragod Patla and P Jayaprakash of Ponnangala – have come to the aid of the Malayalee patients who are dependent on medicines from Mangaluru. 

The three activists who are currently staying (in fact stranded amidst lockdown) in Mangaluru, are delivering life-saving medicines to patients in Kerala through Kerala fire servicemen and policemen posted at the Talapady border. 

Anoop Kumar says that took the initiative after a woman, Maria Augustine from Chemberi (Taliparamba) Nellikkutty, contacted him for a medicine. He managed to buy it from a medical store in the port city and handed it over to a Kerala fire serviceman at Talapady border. 

All three are activists of Communist Party of India (Marxist). After moving to Mangaluru, they set up ‘We Donate Charitable Society’ to donate blood. The activists say that they are ready to dispatch medicines from Mangaluru to any person in Kerala. Those Keralites who are in need of medicines from may contact: 888471344 - Anoop, 9895135881 - Jayaprakash
