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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Chikkamagaluru, Jul 22: Nine staff of the Anti Naxal Force (ANF) in Koppa in the district were tested positive for Covid-19 on Wednesday.

Health officials said that these people don’t have any contacts outside as they were in the forest buffer zone. Now efforts were being made to find out how they contacted the Coronavirus.

Meanwhile, the Kalsa police station has been sealed down after four of its personnel tested positive.

Bangalore , Mar 24: Bizom, India's leading retail intelligence platform, announced free subscription of its retailer app and tele-ordering solutions for consumer businesses in India and other emerging economies. Both solutions enable retailers to send their orders directly to the brand.
In COVID-19 times of social distancing and prophylactic measures, brands are conscious about the safety of their salespersons. Also, retailers don't want travelling salespeople to enter their premises. Consequently, many retail stores are facing stockout situations of fast-moving product categories. Bizom's self-ordering solutions help brands to avoid stockouts of their products.
Bizom trends, which analyses consumption and demand for consumer brands, showed how a near-complete shutdown during the Janta Curfew followed panic buying in early March. The asymmetrical demand and a lack of salespeople for order-taking are driving the industry towards social-distancing-based store-stocking mechanisms.
Bizom provides social-distancing-based store-stocking solutions for consumer businesses. They include the Bizom Retailer App and the Bizom Tele-ordering.
The Bizom Retailer App enables self-ordering for a brand's key retail outlets and can be implemented in under two weeks. The mobile app, a B2B shopping app, is a simple installation for retailers. It lists and groups the brand's products as per its product categories. The app's interface is no different from that of leading e-commerce apps. All the user has to do is select the preferred SKUs and add them to their shopping carts.
The app also allows brands to customize the app to meet the requirements of their continually changing product categories. For instance, if an SKU runs out of stock, the brand can disable the given SKU from the app.
With the Bizom Retailer App, brands can take orders directly from retailers instead of the traditional order-taking approach, which requires high-touch from a salesperson. Some of the key features of the app are, the ability to provide product information directly through retailers including SKUs, competitor comparison and pricing.
It also enables self-ordering from the retailer to maintain the flow of products as per demand, enables scheme rollout information through a notification on the app rather than through salespeople, tracks delivery of goods to the retailer and enables incentive payments to retailers directly rather than through distributor claims.
With Bizom Tele-ordering, as the sales teams go remote, the tele-ordering solution will become useful for brands who want to get salespeople to take orders from retailers, remotely. It ensures continued service to outlets despite not being physically present in the market.
Here, salespeople can discuss product requirements with retailers and enter orders based on specific outlet types (grocery, chemist etc.), outlet class (Class A, Class B etc.) or based on their beat or as per a distributor.
The key features of the Bizom Tele-ordering solution are, its ability to help salespeople collect orders from retailers remotely and enter it for fulfilment into Bizom using a tool, the flexibility offered to salespeople for remote servicing of retailers as per outlet type, beat, distributor area etc., secondary schemes get applied automatically, variable discounts will get applied as applicable at an SKU level.
"At Bizom, we are conscious of our responsibility to help brands run faster during these COVID-19 times. Our solutions of Bizom Retailer App and Bizom Tele-ordering have been built to ensure that brands can leverage this situation of low direct touch with retailers to enable a better way of working, remotely. I am trying to help brands go live in a few days so that they, in turn, can serve consumers better during these testing times," said Lalit Bhise, CEO, Bizom.
