I will try my best to never buy anything from the slants ever again !

We have been trying to do that for years.
I especially love my British made work boots, the quality is unbelievable.

Aye, your attitude is. 

This isn't an attack on us from China. If anything, based on reports from there, they did a bloody good job of containing it as far as they have done. And if the UK had taken their advice we'd potentially be in a more favourable position now. 

Please don't turn this into an opportunity to incite hate. 

I heard they have reopened the animal market in a new site , same conditions ...

Which I worry is how so many medics are succumbing  to it, true a droplet can contain many viruses and falls to the floor quickly but the virology suggests a virus has a half life in air of 3 hours. What is unknown is what viral load entering the lungs will overcome normal defences.

Where is the science for it being airborne for 3 hours? If that was true I think we would all be in a far worse situation than we are now.

 

What I want to know is why on earth haven't they quarantined London yet?

Doesn't surprise me. A neighbor used to work there, said the place, the food and the people were disgusting. I also watched "An idiot abroad" when Karl visited china so I'm a bit of an expert on these matters.

You misquoted me, I reported a half life in air.

A quote from this lady:

 

Dr. Angela Rasmussen (interview recorded March 15, 2020)

 

"Yeah, so a great pre-print just came out. I like to pitch my collaborators at Rocky
Mountain Labs, this is Neeltje van Doremalen who is with Vincent Munster at NIAI
Rocky Mountain Labs have just released a preprint with some of their colleagues, I
believe at Princeton, showing that SARS-coronavirus-2 and SARS classic have some
different properties as well as some similar properties for remaining infectious on
various surfaces. So they looked at experimentally generated aerosols, which for
SARS-coronaviruses is only an issue for the most part in hospital settings where
there are aerosol generating procedures, but they showed that for both of these,
the aerosol half-life is only about three hours. So that's good news in that you
know, if somebody that you love or care about is working in a hospital or an ICU or
is getting treated there, these aerosols are not going to persist for days at a time in
the environment. They also looked at survival of the virus on copper, stainless steel,
plastic and cardboard, and the virus lasts the longest on stainless steel and plastic.
So it lasts 48 to 72 hours, and it can potentially be there for longer than that, but
what's important to note is that there was a three-log reduction, so a thousand
times less virus that was infectious after 72 hours. So, even though you can detect
infectious virus on surfaces, plastic or stainless steel surfaces after three days, it's a
greatly reduced amount of virus. Compared to SARS classic, SARS-coronavirus-2
lasted longer on cardboard, however it didn't last longer than 24 hours. So before
everybody gets worried about getting packages in the mail or opening letters or
calling, ordering stuff from Amazon it, it also was essentially undetectable after 24
hours. So cardboard is probably not a surface that's going to retain the virus for, for
days and days at a time. What we don't know is the effect that temperature and
humidity and other environmental conditions would have on this "

Well that’s cleared that up then?

Yes I'm going to work tomorrow

Sorry, can you explain that for me then please? It sounded like you said the virus can remain in the air for at least 3 hours.

The WHO says that "according to current evidence," the virus is transmitted through "respiratory droplets and contact routes." By that, the agency means the virus is found in the kind of big droplets of mucus or saliva created through coughing and sneezing.

These droplets can travel only short distances through the air and either land on people or land on surfaces that people later touch. Stopping this kind of transmission is why public health officials urge people to wash hands frequently and not touch the face, because that could bring the virus into contact with the nose or mouth.

 

Other viruses, however, get shed by infected people in a way that lets the germs actually hang suspended in the air for minutes or even hours. Later, these airborne viruses can get breathed in when other people pass by. Measles is a good example of that kind of transmission — the Centers for Disease Control and Prevention says, "Measles virus can remain infectious in the air for up to two hours after an infected person leaves an area."

 

 

Among patients infected with SARS-CoV-2, viral loads in the upper respiratory tract are high; as a consequence, respiratory secretion in the form of aerosols (<5 µm) or droplets (>5 µm) is likely, the authors note.

van Doremalen and colleagues used nebulizers to generate aerosols. Samples of SARS-CoV-1 and SARS-CoV-2 were collecting at 0, 30, 60, 120, and 180 minutes on a gelatin filter. The researchers then tested the infectivity of the viruses on Vero cells grown in culture.

They found that SARS-CoV-2 was largely stable through the full 180-minute test, with only a slight decline at 3 hours. This time course is similar to that of SARS-CoV-1; both viruses have a median half-life in aerosols of 2.7 hours (range, 1.65 hr for SARS-CoV-1, vs 7.24 hr for SARS-CoV-2).

 

they have to do the research, but then release the results in a way that won't make people too worried, difficult job
