Britain started to prepare for the Second World War at least a year before it actually started. The government expected the war to disrupt and threaten the lives of civilians left at home. Between 1938 and 1939, the government thought of all the possible dangers and difficulties the Home Front would face during war, and started to take precautions. People were encouraged to think about their safety, and the government spent a great deal of time educating people on what to do in situations such as an air raid, or a gas attack, as well as providing information on how to make rations stretch further and how to keep yourself healthy. By September 1939 some 38 million gas masks had been given out, house to house, to families in Britain. Actually, everyone in Britain was given a gas mask in a cardboard box, to protect them from gas bombs, which could be dropped during air raids. Posters reminded people to carry their gas mask at all times. People were fined if they were caught without their gas masks. There was a special gas mask for children .....and for babies.

And in 2020 Britain doesn't have enough PPE for medical workers!!!

Remember that well CJ. I had a Donald Duck gas mask, and my older sister had a Minnie Mouse one.Had to wear them for aprox an hour a day to familiarise ourselves with them. What i remember most was the horrible rubbery taste it left in my mouth.

"In the latest World Health Organization recommendations for COVID-19, health care personnel and other staff are advised to maintain a 3-foot (1-m) distance away from a person showing symptoms of disease, such as coughing and sneezing. The Centers for Disease Control and Prevention recommends a 6-foot (2-m) separation. However, these distances are based on estimates of range that have not considered the possible presence of a high-momentum cloud carrying the droplets long distances.Given the turbulent puff cloud dynamic model, recommendations for separations of 3 to 6 feet (1-2 m) may underestimate the distance, timescale, and persistence ov er which the cloud and its pathogenic payload travel.

Recent work has demonstrated that exhalations, sneezes, and coughs not only consist of mucosalivary droplets following short-range semiballistic emission trajectories but, importantly, are primarily made of a multiphase turbulent gas (a puff) cloud that entrains ambient air and traps and carries within it clusters of droplets with a continuum of droplet sizes. 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. 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.

Multiphase Turbulent Gas Cloud From a Human Sneeze


Owing to the forward momentum of the cloud, pathogen-bearing droplets are propelled much farther than if they were emitted in isolation without a turbulent puff cloud trapping and carrying them forward. Given various combinations of an individual patient’s physiology and environmental conditions, such as humidity and temperature, the gas cloud and its payload of pathogen-bearing droplets of all sizes can travel 23 to 27 feet (7-8 m). Importantly, the range of all droplets, large and small, is extended through their interaction with and trapping within the turbulent gas cloud, compared with the commonly accepted dichotomized droplet model that does not account for the possibility of a hot and moist gas cloud.

Droplets that settle along the trajectory can contaminate surfaces, while the rest remain trapped and clustered in the moving cloud. Eventually the cloud and its droplet payload lose momentum and coherence, and the remaining droplets within the cloud evaporate, producing residues or droplet nuclei that may stay suspended in the air for hours, following airflow patterns imposed by ventilation or climate-control systems.

A 2020 report from China demonstrated that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus particles could be found in the ventilation systems in hospital rooms of patients with COVID-19. Finding virus particles in these systems is more consistent with the turbulent gas cloud hypothesis of disease transmission than the dichotomous model because it explains how viable virus particles can travel long distances from patients.

With other words, if you live in a flat make sure the ventilation in your bathroom is sealed !!!

Then on a windy day I would think it's fair to assume you are far more vunerable walking among the general public.

The 6 ft rule is a nonsense. That bright people supposedly experts in infectious disease can spout this is disturbing. @Crojack’s post above is a great analysis of what is fundamentally common sense. After all, who among us has not been overcome by an SBD from across a room, that has passed through at least one layer of clothing.

On other news ... A 6 week old child just passed from this locally. In the county where I live, primarily rural, we have as of yesterday only 66 cases, but 7 deaths. Not a good ratio >10%. The young are not without risk. It appears that the "virus load" (how much virus you're exposed to) is a factor in how seriously your body insult is and the impact of the infection.

This is a good interview of Korea’s leader in the field:

Trying to find some light relief in all this and was really amused by this great observation from Rod Little in the Sun.

MIDDLE v WORKING CLASS DURING LOCKDOWN:

MIDDLE CLASS: Sacking the nanny and the cleaner in case they give the virus to Cressida, two, and Wolfgang, four.
Growing hydroponic vegetables in the annex, enough for half a salad by next February.
Writing letters of complaint to the board of Waitrose about the unavailability of dried black limes and manchego.
Stockpiling hummus.
Cycling around the local park wearing chemical warfare gear.
Trying, desperately, to sell their three-bedroom cottage in North East Italy.
Washing their hands every 18 seconds with Duchy Original Organic Fair Trade Hand Sanitiser.
Trying to fit a face mask on Corbyn, their Labrador.
Removing the back seats from the Range Rover for the next click and collect.
Hoping to get a nice postcard from their oldest son, Oliver, who has been on his gap year in Wuhan.

WORKING CLASS: Getting pissed watching Netflix.

Rod then quotes his favourite observation online about this virus.

"January 1 - yeah, this is gonna be MY year!
"March 27 - wiping my arse with a pot noodle lid".

Love it!!

That's one of the best, if not the best, interviews I've seen on coronavirus. He knows what he is talking about. No bullshit. Common sense.

And this is hilarious:

"The western governments say that wearing a mask doesn't help because they don't have any masks." So true.

Went to Tesco the other day, bought some groceries then went to the tobacco kiosk. I usually used to buy 3 packs of ciggies at a time knowing I'd do a second or even third shop during the week when I'd buy some more. Now, being regarded as highly vulnerable to this sodding virus, I decided to buy 5 packs to last the week to save me going out again.

The old guy that served me was very friendly and polite but said that he could only let me have 3 packs as selling a maximum of 3 of anything was now the store's policy. I argued that this would mean that I'd have to make a second trip that week which, of course, I really didn't want to do. He was very apologetic but adamant that he couldn't let me have the 5 packs.

Then in the next breath he said that he'd be allowed to sell me 3 CARTONS if I wanted. No, I didn't want!! Three cartons equates to 30 packets of smokes and I only wanted 5!!! Where's the sense in that??? Anyway, I took my 3 packs and got 2 more at their filling station in the car park. I wish that the policy makers would think things through a little more carefully. But I also wish that I didn't smoke!

Closing the borders early and social distancing measures have payed off. Some good trends in Denmark.

A 4 year old tiger has tested positive for Coronavirus in an American Zoo.
Is this the start of another huge threat from the animal kingdom?

Now been reported 6 other big cats at the same zoo have tested positive.

Coronaviruses have always been around. There are hundreds of them, and only seven of them cause a disease in humans. Four of them cause common cold, which we all get infected once or twice a year. Three of them cause serious illness: SARS-1, MERS, and this one SARS-2/Covid-19. Covid-19 is actually the least dangerous of these three.
It's same with animals, they regularly get infected with coronaviruses.

It is less known that every year 7% of all acute respiratory distress (ARDS) is caused by common flu and 15 % by some sort of coronavirus. The difference is that we have never tested people for a specific coronavirus like we do now in 2020, because this mutated coronavirus is simply too dangerous. Too many people develop ARDS and need intensive care.

Imagine if this gets into livestock. It could devastate a farm.

It is curious that the red curve is approximately quadratic then abruptly plateaus. There is no curve into the plateau; it just flattens.

I am seeing nothing but quadratics in cases and deaths in Connecticut. Death rate in my county is still 10% of cases.

It's surely causing some concern to be making News Headlines.

Boris Johnson has just been taken into intensive care. Now it's 50% - 50%. Not good.

I'm heart broken.

How is going with the place where you live in Turkey?

@Jackflash

How is going with the place where you live in Turkey?

I'm in the S/West on the Aegean Coast. It's at its worse up the North Istanbul area which is aprox 400 road miles from me, but it's creeping South at an alarming rate. Death total still low atm (early days) 500/600. I'm on total lockdown, if I need to go out for anything important ie. pharmacy, doctors, I have to ring the police and they will escort me there and back. Also they call me almost daily checking I've got someone shopping for my needs.

Stay safe mate, glad they are keeping an eye out for you !
