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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Jun 8: Amid the relaxations in the coronavirus-induced lockdown, wedding planners are adapting to changing times and advancing themselves to provide best possible services to their clients.

Wedding planners come up with new trends. While women are matching their masks to their outfits, men who use turban for a wedding are wearing matching masks with the turbans. People are getting creative at the same time maintaining safety protocols. The live streaming of weddings for those who could not attend the wedding is also becoming a new normal.

Manisha Porwal Chouraria, a wedding planner at Color Palette Productions speaking to news agency said that Post COVID-19, weddings are performed as per the old cultures.

"Wedding Industry has impacted due to lockdown in the wake of COVID-19. Now, the concept of micro-wedding is trending in which you have guests who are close to you. Now, the old culture is back again as people who use to hold a wedding at lavish destinations are getting married in their lawns, farmhouses, terraces. Earlier, people used to get married in their 'Aangan' (Courtyard), people seem to be doing the same now. It is more personalised and expenses have come down, now. People are spending small amounts on decoration," said Chouraria.

"Following government guidelines, we are allowing 50 people at the wedding and not more than that. We are doing live streaming telecast and people can watch the wedding. We are also shipping gift boxes with a letter to 500 people who could not become part of the wedding. In the letter, we are writing that because of norms, you may not be invited but we want something to gift you on our wedding. People are planning to get married now and decide to throw a grand reception after 6 months in the hope that things will get better," she added.

Commenting upon how wedding planners are ensuring social distancing and how the fashion style changed due to pandemic, Chouraria said: "People are using matching masks. If women are wearing silk sarees, they are also wearing silk masks. Men are wearing matching masks with saafa (turban). The entire staff is asked to wear PPE kits. We are giving the guests a healthy kit comprising up of masks, sanitisers, gloves and tissues. We are doing thermal screening of the guests. We are also gifting cuddle curtains, a plastic transparent shield by using which you can touch feet of elders without physically touching them."

Mansi Porwal, Creative Head at Color Palette Productions said that it is becoming a challenging task for creative heads to plan wedding but still they are providing their best to the clients.

"Earlier people used to do theme wedding, big Indian Fat weddings. Now people are wedding with a small gathering. Now, family members are getting time to suggest the wedding planners about themes and the thing they want in their weddings. We are providing the best," she said.

"We have come up with a new theme, 'Har Din Subh hai' which means every day is auspicious. Post COVID-19 people are looking for available dates for the wedding. Now, every day becomes auspicious. This is going to be the new trend," she added.

Another wedding planner, Abhilash of Taarini Weddings said that their company is providing customised masks to guests.

"Earlier we have lots of weddings to cover across the globe. But now, we have less numbers of weddings. Budgets are reduced now. We are happy to start again. We are creating e-invites in which we are sending the guidelines to the guests. We also have a help desk to assist the clients and guests. We are providing the matching masks to the groom and we are also giving customized masks to guests too," he said.

Earlier, Karnataka's Department of Health and Family Welfare Services had issued an advisory for marriages, stating that not more than 50 guests shall be allowed and the consumption of liquor on the occasion will be prohibited.

As per the advisory, anyone found having fever, cold, cough, difficulty in breathing shall not be permitted to attend the event and immediately referred to seek medical advice.

"All persons shall wear face mask compulsorily. All persons shall maintain a physical distance of more than one metre. Hand wash with soap and water shall be provided in washrooms," adds the advisory.
