State-sponsored terrorism most dangerous: Dr Shridhar

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

The covid-19 lockdown has thrown wedding plans in disarray in coastal Karnataka like all other activities involving a crowd of people. While many people chose to postpone the scheduled and about to be scheduled weddings, some are going ahead with scheduled plans and holding weddings with no more than 50 guests as per the guidelines issued by the government of Karnataka. 

The government may relax the norms and allow participation of more guests in the future. However, holding wedding ceremonies will be a new challenge when people are returning to a ‘new normalcy.’ Compared to the traditional wedding ceremonies of the region, marriages in the time of Covid-19 are expected to be smaller as the organizers have to adhere to the safety protocol and safe distancing norms. Given this situation, to limit risks and ensure safety, families now will have to consider wedding planners to help them celebrate their weddings.

“The postponed weddings will take place in the coming days as the lockdown is being relaxed in a phased manner. However, it won’t be like our traditional weddings. There won’t be 3000 guests.  Government directives will be have followed. We expect change in trend from big fat weddings to a small, close family, picture perfect weddings,” says Sartaj Beary, Managing Partner, Zawaj Weddings and Events.

“Our curetted packages will take care of wedding invitations, outdoor venue, premium catering, bridal make up, mehendi function, photography, videography, décor, thermal scanning systems, hand sanitizers and N 95 masks etc. We hope with our experiences we can offer stress free celebration to the families while we plan everything from scratch as per client requirement,” he assures.

“Ultimately, our society has to adopt an innovative way of marriage. At this point, we can say that any wedding in 2020 will look different as the novel coronavirus has disrupted the weddings everywhere. We know it is a big milestone for families and we at Zawaj are here to assure families that we can help a stress free wedding,” he adds.

New Normal Era Weddings

In the ‘new normal era’, weddings across the world will be totally different from what we used to see before the pandemic. People need to be cautious while attending mass gathering and it is important. Gone are the days of closed AC venues. Outdoor weddings will be the future, where seating are spread out and space between tables, stage, food counters will be maximum as per  safe distancing protocols. 

Wedding planners and caterers will have to ensure systematic safety protocol, safe and responsible operations, preparation of the food, event crew and vendors safe zone, sanitized kitchen, transportations. Even buffet settings will change to include smaller but multiple cuisines, self serving stations, markings on line to maintaining safe distance at the food counters.

More importantly, venue has to be prepared as per the government instructions. Things like disinfection and sanitization, hygiene, ample toilet facilities, hand wash, thermometer scans, masks, sanitizing stations should be taken care of. People from all walks of life will embrace this form of marriage. The services of wedding planners will be most opted in future.
