I could use some of that 
ā¦ā¦ do you have a source link?
The formulaās been changed to only vinegar and waterā¦
This specific stain has not been tested. Several other corona strains have, with varying survival times up to 9 days. I skimmed the meta-study summarizing these findings, but didnāt see details in it about what surival meant in this case. There is difference between surived well enough to regrow in an ideal culture or survived well enough to be contagious.
If this virus really is contagious enough to spread other than as a rare exception through surfaces that were briefly handled by an assymptomic person hours or days before, then I donāt see how it could be possible for less than 1% of Wuhan to be infected after 3+ months.
But perhaps it really is that contagious, in which case the conclusion would be that there is likely a huge number of unknown cases with only mild symptoms.
By brother works for a major resort in South Lake Tahoe and there is a rumor right now that they have a woman in quarantine. We have family that works in the Barton Memorial hospital and a couple more family members in the Carson Tahoe hospitals in Carson City, Minden and Gardnerville Nevada. Iāll find out in a week or so if the woman in Tahoe has the virus. A little to close to home if true.

Itās Chinaās fault for not locking the gates immediately.
People IN there. Stay there.
People outside of there.
Stay outside of.
Same as Aust Govāt. US etc.
NO in/out of any of those countryās it wouldnāt have done anything.
Lock both way doors. Nothing goes anywhere.
It goes away.
These people in China. knowing itās there and still trying to get out.
So they can spread it at home and elsewhere on the way.
Should be put down.
Now. Because of greed and disrespect for others. Itāll get everywhere.
Hmmm. Maybe not a bad thing.
Reduce the populations a coupla/twenty million hey.
Humans are due for a shock one of these times. we only flesh and blood.
Same as the other 90+ % of mamalians that have disappeared off this planet
over the last 400 Mill yrs or so
Just maybe our time. This time around.
We are NOT going to last forever.
One shrug of the planet.or decent sized satellite
We ALL gone anyway.
There is NOOO god to save you all.

I think you need to get back onto your medication, advocating genocide by the killing of over a billion people sheeesh.

but he is right tho, the borders for in and out must be closed, no exceptions otherwise just more and more will spreadā¦.

Because as we know itās totally possible to shut down borders, and none of the people in the affected area would try and get their families out.

The chinese were late in realising what the calamity was (would we do better?) and taking action, but did an effective job limiting the spreading of the disease in their country, something that other countries still have to show. Completely shutting down the chinese borders (if the disease would not have travelled abroad already before it was discovered at all) would maybe have been a disaster, not only for them, Iām not sure what the effect on the world would have been of a complete standstill of China for a few months.
LOL!
thanks for the comic relief
I needed that
I just heard on the radio to be very careful of receiving any packages from China, They said if the person that packaged your item was sick it could possibly transmit the virus to you??? Is that even possible for a virus to live outside a host for two to three weeks? If so, HOLLY CRAP!!! Any biologist here that could verify if any virus could live that long without a host? Sounds like fear mongering to me but then again it is a new bad guy on the block. Thoughts anyone.

No ,no biologists here that can verify, but thereās a few who think they can !

> heard on the radio
Now what kind, AM or FM? what program, who was speaking, and what were that personās qualifications?
You can hear some godawful crap on the radio these days.
Best advice is to search for answers at the CDC.

Thanks for the information Hank. 
jon_slider, thanks for the post. That was one hell of a read!
Sampling intervals were chosen after preliminary experiments to assess the maximum length of virus survival were performed. At 4Ā°C and all RH values and at 20Ā°C and 20% RH, carriers were sampled at 7-day intervals for up to 28 days. At 20Ā°C and 50% RH or 80% RH, carriers were sampled at 24-h intervals until virus was no longer detectable. At 40Ā°C, carriers were sampled at 2-h intervals until virus was not detectable. Based on virus recovery experiments, 1.5% beef extract (pH 7.5) was used to elute viruses from carriers (data not shown). At desired time points, carriers were removed, placed in a 24-well plate, and covered with 1 ml beef extract. Viruses were eluted by agitation on a shaking platform (60 rpm) for 20 min at room temperature. Eluted samples were diluted in cell culture medium, and virus infectivity was assayed using the appropriate host cell line. Three replicate carriers were assayed per time point. The virus survival at each time point was expressed as log10(Nt/N0), where Nt is the virus concentration (in MPN/ml) at time t and N0 is the initial virus concentration (in MPN/ml) in the control sample at time zero.
RESULTS
Inactivation of TGEV and MHV over time was measured for nine combinations of AT and RH. The survival of TGEV and MHV at 4Ā°C and three RH levels is shown in Fig. ā
Fig.1.
- At 4Ā°C, infectious virus deposited on stainless steel surfaces at initial levels of 4 to 5 log10 MPN persisted for as long as 28 days, and the lowest level of inactivation over the 28-day experiment took place at 20% RH. There was a decrease in the observed log10 inactivation rate at 20% and 50% RH from day 21 to day 28. To better simulate the physical state in which viruses in patient secretions are deposited onto surfaces, viruses were not dispersed before inoculation. Therefore, possible clumping and aggregation effects may have resulted in variation in the physical state of the viral inocula on individual carriers, possibly contributing to the variations in the rates of reduction observed. With the exception of the 20% RH model, every linear regression model was statistically significant (P < 0.05) (the coefficient of the linear model was not equal to zero). The slopes of regression lines for TGEV and MHV inactivation at 4Ā°C and each RH are shown in Table ā
Table1.
- The levels of both viruses declined by <0.5 log10 over 28 days at 20% RH. Greater reduction took place at 50% RH, at which the levels of both viruses declined by ā¼3.5 log10 after 21 days. At 80% RH, the TGEV level declined by 3.2 log10 over 28 days, and the MHV level declined by 2.5 log10.
Most of us at BLF are rational thinking creatures, you know, like: 2+2=4 and stuff.
But I find the nomenclature used for this epidemic sometimes pretty confusing.
I found a PAGE on the World Health Organisation (WHO) website were itās all explained.
Official names have been announced for the virus responsible for COVID-19
(previously known as ā2019 novel coronavirusā) and the disease it causes.
The official given names are:
Disease: - coronavirus disease => COVID-19
Virus: - severe acute respiratory syndrome coronavirus 2 => SARS-CoV-2
