Artisans facing uncertain future due to mass production of ‘gods’

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jan 17: An auto-mobile shop at Deralakatte here caught fire on Friday incurring huge loss on the shopkeeper.

According to police, the incident happened in the morning when the shop owner opened the shop.

Locals suspect that miscreants might have set the shop on fire and had escaped from the scene at night.

Wayanad, Jul 6: DM Education and Research Foundation (DMERF), headed by Dr Azad Moopen, has come forward to handover DM WIMS Medical College, Nursing and Pharmacy Colleges and its associated institutions in Wayanad to the Kerala Government. 

According to Azad Moopen, Managing Trustee, DMERF, the Kerala Government has been deliberating to set up a medical college in the area over the last 7-8 years to address the challenges being faced by the local population due to lack of local availability of advanced healthcare facilities under the government sector. 

The handover by DMERF would address the Government's need. DM WIMS is one of the few NABH accredited medical colleges in the country, he said.

The DM WIMS Medical College and its associated institutions were established by the DMERF Trust 10 years ago to help the backward community of the district. 

Run in a charitable manner, the medical college has a capacity of 150 seats and has seen two batches of doctors graduate from the institution. With a total built up area of 14 lakh sq feet, it also has a 700-bed super-specialty hospital catering to the local community and helping in training healthcare professionals, a 100-bed specialty hospital, a pharmacy college, and a nursing college.

A new medical college by the government will require substantial investments and minimum of 5 years to become functional. “We think that DM WIMS can cater to the requirement of the government and setting up another medical college might not be required to cater to the existing population,” he said.

Moopen also announced a donation of Rs 250 crore out of the total investment in the institutions to the government to provide treatment to the needy population in the backward, landlocked district and to train good quality doctors from the State.
