27 feet?

What's in the air: Why CDC says to wear masks
6 feet enough for social distancing? MIT researcher says droplets carrying coronavirus can travel up to 27 feet
JORDAN CULVER | USA TODAY | 10:42 am EDT March 31, 2020
Social distancing matters. Here is how to do it and how it can help curb the COVID-19 pandemic.
JUST THE FAQS, USA TODAY
The novel coronavirus has prompted social distancing measures around the world. One researcher believes what's being done isn't enough.

Lydia Bourouiba, an associate professor at MIT, has researched the dynamics of exhalations (coughs and sneezes, for instance) for years at The Fluid Dynamics of Disease Transmission Laboratory and found exhalations cause gaseous clouds that can travel up to 27 feet.

Her research could have implications for the global COVID-19 pandemic, though measures called for by the Centers for Disease Control and Prevention and the World Health Organization call for six and three feet of space, respectively.

“There’s an urgency in revising the guidelines currently being given by the WHO and the CDC on the needs for protective equipment, particularly for the frontline health care workers,” Bourouiba told USA TODAY.

There are 8 strains of coronavirus circling the globe: Here's what clues they're giving scientists.

Bourouiba’s research calls for better measures to protect health care workers and, potentially, more distance from infected people who are coughing or sneezing. She said current guidelines are based on “large droplets” as the method of transmission for the virus and the idea that those large droplets can only go a certain distance.

In a Journal of the American Medical Association article published last week, Bourouiba said peak exhalation speeds can reach 33 to 100 feet per second and "currently used surgical and N95 masks are not tested for these potential characteristics of respiratory emissions."

The idea that droplets "hit a virtual wall and stop there and after that we are safe," is not based on evidence found in her research, Bourouiba said, and also not based on "evidence that we have about COVID transmission."

Bourouiba argued that a “gaseous cloud” that can carry droplets of all sizes is emitted when a person coughs, sneezes or otherwise exhales. The cloud is only partially mitigated by sneezing or coughing into your elbow, she added.

“In terms of the fluid regime – how the exhalations are emitted – the key point that we have shown is that there’s a gaseous cloud that carries droplets of all sorts of sizes, not ‘large’ versus ‘small’ or ‘droplets’ versus ‘aerosols,’” she said.

How far can coronavirus germs travel 'before they're no longer a threat'?
Dr. Paul Pottinger, an infectious disease professor at the University of Washington School of Medicine, said questions remain about the distances at which the virus is effective.

“For me, the question is not how far the germs can travel, but how far can they travel before they’re no longer a threat. The smaller the germ particles, the lower the risk that they might infect somebody who would breathe them in or get them stuck in their nose or their mouth,” Pottinger told USA TODAY. 

“The biggest threat – we think – with the coronavirus is actually the larger droplets. Droplets of saliva, snot, spit. Droplets that almost look like rain, if you will, when someone sneezes. Those droplets are large enough that gravity still acts on them. Usually, within about six feet of leaving somebody’s body, those larger, more infectious droplets will drop to the ground. That’s where the six-foot rule comes from.”

WHO referred to a recent scientific brief on the methods of transmission, which recommended "droplet and contact precautions for those people caring for COVID-19 patients." The CDC did not respond to an emailed request for comment.

“WHO carefully monitors emerging evidence about this critical topic and will update this scientific brief as more information becomes available,” WHO said in a statement. “WHO welcomes modeling studies, which are helpful for planning purposes. WHO teams work with several modeling groups to inform our work.”

If you're not afraid,  be afraid
If you're afraid, be more afraid
and if you're more afraid, be scared to death.

It seems to be a cull, controlled, somewhat.

Droplets suspended in the air from infected persons.Also Supermarkets wear gloves ,as food handled by many people. Wipe when get home with wipes

Have supermarkets introduced hand sanitisers yet?
