So, a Jazz player tested positive for Corona, he stupidly touched a microphone and other things on his area while beginning to speak to news press. WTF, is my statement but ignorance is not bliss. If we understand more about this virus we begin to now more about how bad it is or not. Why would they begin the process of canceling anything related to large events or small closed areas if not to cover the easy spread of something that will move through a population. It’s not that it spreads but that they have no idea what or how it will mutate.

I wasn’t concerned until now, but now I’m beginning to rethink my options. Don’t go gently into the night, but fight.

Don’t go gentle into that good night. Old age should rage at close of day; Rage, Rage against the dying of the light. Though wise men know at the their end dark is right, because their word had forked no lightning. They do not go gentle into the night.
Good men, the last wave by, crying how bright
Their frail deeds might have danced in a green bay,
Rage, rage against the dying of the light.

Wild men who caught and sang the sun in flight,
And learn, too late, they grieved it on its way,
Do not go gentle into that good night.

Grave men, near death, who see with blinding sight
Blind eyes could blaze like meteors and be gay,
Rage, rage against the dying of the light.

And you, my father, there on the sad height,
Curse, bless, me now with your fierce tears, I pray.
Do not go gentle into that good night.
Rage, rage against the dying of the light.

let's not allow this to morph into 'the new politics thread', ...k?

Not that it's gone 'that way' yet - but when (figuratively) standing ankle-deep in a pool of petrol, burning match in hand - stuff can and does happen!:eek:

At your mercy, sincerely

Don't worry, the thoughts of slow death unites us. The Coronavirus has no political affiliation, it's the Alien Mothership landing.
FLATTEN THE CURVE

Is it time to panic yet? If no, when?
Right off hand I'd say never! Panic solves nothing! -- Not even real (i.e. 'above background') problems!

IMNSHO the real threat is posed not by COVID-19 and its (health) corollaries - but, rather, the absurdly 'over the top' reaction{s} to perception/anticipation of same... Please relax! The Sky is up!:)

Best regards

At last, something one does not need to pay to read: https://www.journalofhospitalinfection.com/article/S0195-6701(20)30046-3/pdf
Note, uses SARS-CoV-2 and COVID-19 to refer to the current virus.

... but can be efficiently inactivated by surface disinfection procedures with 62 to 71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute. Other biocidal agents such as 0.05 to 0.2% benzalkonium chloride or 0.02% chlorhexidine digluconate are less effective.
Ordinary chlorine bleach is about 5% to 6% sodium hypochlorite (NaOCl). 0.1% (1000 ppm) is approximately a 1:50 dilution. For lab use, we often used a 1:10 dilution, but that is quite harsh and unnecessary. 1:100 is far less harsh, but will still bleach fabric. One thing to remember is that those percentages are for freshly prepared dilutions. It does decompose by itself and with exposure to light, which is why the laboratory "grade" is so concentrated..

I would assume Isopropyl would be as effective as Ethanol (preferred for laboratory work) since Everclear is quite expensive and denatured Ethanol not readily found. Methanol (wood alcohol) should NOT be used.

:rolleyes:

Ah, yes. Important announcements sent by some anonymous person who heard something from a friend who got something from an uncle who has a master's degree in some unstated field that supposedly works at a hospital must be true.
Do you care to disagree with any of the suggestions listed?

I would agree. Isopropyl alcohol (IPA) is actually more active against ordinary bacteria than ethanol. As you point out, methanol is inactive against most bacteria. Table II in the link includes these data:
Ethanol >= 78% effective in 30 seconds or less
Ethanol 70% = 10 minutes
IPA >= 70% = effective in 30 seconds or less
IPA 50% = 10 minutes

The same table shows lower concentrations of NaOCl are effective at 10 minutes. That is consistent with ordinary bacteria and viruses too. Table III has additional data.

Remember that contact time is always important. Other materials (like blood or serum) will usually act to decrease effectiveness. So, if you want to clean up a mess, one usually cleans the mess first (everything goes into hazardous waste), then disinfects. Adding disinfectant to the mess may tend to increase the area covered by it and can be done, so long as you finish with disinfectant. One technique is to cover the mess with paper towels, saturate with a bleach solution, let stand 10 min or more, clean up the mess, then disinfect.

As for the "dry cough" symptom, remember other things, like dust can cause that. In fact, one of the side effects of common anti-hypertensives is a cough that can be productive (foamy sputum) or dry.
