    Be careful of the home remedies.

    Hand sanitiser based on alcohol should contain at least 70% alcohol.

    (Referring here to ethanol. I don't know about iso propanol which is also a base for some sanitisers.)

    Perhaps a few good snorts of your favorite whiskey in the nose, as they call for hand sanitizer containing at least 40% alcohol I believe.....

    HW's point about salt brings me to share my own experience.. Years ago, while my daughter and I were suffering a really nasty cold in France, the excellent pharmacy supplied a crate of goodies to get us more comfortable and aid recovery. The salt bit of this story is a box of 50 5ml soft plastic phials of 5% saline, to be trickled down the nose while slightly tilting the head back, to keep airways clear and preventing discomfort from drying out. It worked so well for me and my 8 year old daughter that I still do it years later when I think there are bugs around. She isn't so keen... I dissolve sea salt in a jar of very hot water, and do the trickling of the cooled solution with a small syringe, twice a day if I feel the slight tickle in my throat which is normally the harbinger of a bug getting hold, to 3 or 4 times if the throat is sore and I'm feeling optimistic. MOST times, the onset of the bug is delayed as long as I remember to take this preventative action. Sometimes not. In all cases where the cold has "won", I find the 3 or 4 times per day while I have symptoms keeps airways clearer and  me more comfortable. There are expensive preparations available from pharmacies which I think are meant to do the same thing, but the packaging and cost puts me off, and they do "taste"  completely foul. A friend of mine swears that if he is getting a cold he nips down to the beach in front of his west Scotland home and  takes a few big snorts of the Clyde! His wife says he very rarely gets a cold. My saline is FAR weaker than the salt sea.

    The home-made stuff does seem to be effective prevention until I forget to take it, or feel I'm past the danger phase and relax the procedure too early. Otherwise it is - anecdotally - an effective prevention. I'm on three "snorts" a day at the moment, and do an extra one after handwashing etc following a trip to the shop. I think it was Darren who mentioned the sensitivity of eyes and nose to collecting virus compared to the mouth. I'd be really interested to know what's going on here with the salt trickling, and whether simply washing the nasal passages is doing the almost the same as handwashing?! And how is it that the little blighters do seem to hang in there, and occasionally get me in the end?!

    Where C-19 is concerned, I am willing to try anything. Wearing a clean "tube" or buff  scarf pulled up over my nose and mouth while in the shop for 20 mins or so today  made me very aware of NOT touching any part of my face. I removed it carefully once outside, and it went straight into the wash. But after reading Darren's posts, and elsewhere, I can see that rigorous hygiene is the best prevention for most of us on a short-as-possible shopping trip. And yes I'm piling through the lanolin/simple shea butter and minerals. too :)

    Thanks again to everyone on this, and Happy Birthday Arne!

    It occurred to me which it should  have before I wrote the  last post, that other people would have reached the same conclusion.   If you do a search on "salt masks for coronavirus", you will find many  hits............. I need to search first, and write later ;-)

    Commercial filtration techniques may possibly be of value..... The virus is normally transported in micro droplets of water & mucus which is water soluble.  A medium that is hygroscopic.... that is one that is attracted to water is going to remove the majority of these droplets from air you inhale or exhale.   The most logical material for this in terms of availability and cost is ordinary salt.  Fabric that is saturated in salt water, then over dried, such as a thick felt, could be sandwiched between layers of unsalted material.  There might be several layers.    The beauty of this is that it would trap those drops of moisture both incoming and exhaled, though it's effectiveness would be short lived.   If one counted on an hour as the life expectancy of such a mask, that's  not a very long time, but the could be baked to both remove the moisture and deactivate the virus, so you would only need enough to last the time you were exposed to others, cycling a dozen or so masks throughout the day.   This would be preferable to trying to filter a virus out, which considering the size of the virus is estimated to be 1/10 of a micron, and no mask can filter out anything that small in reality.   Filtration itself is only useful because of the water droplet carrier.   Concentrated salt is a very hostile environment for all microbes I know of.

    Happy Birthday Arne, I look forward to seeing the creativity your 66th year is sure to bring.

    Today is my 48th birthday.  I've spent the morning here enjoying the JRA and this afternoon I'll be heading up the mountain (glorified hill) at the end of the street for some exercise on a quiet trail with my family.

    Thanks for your civility and patience despite our disagreement,

    Darren

    Maybe I’m a bit thick-headed, or maybe we are just talking past each other.
    I fail to see that my facemask will do any harm, the way I use it, so I decide not to erase my write-up.

    Anyway, since there is nothing more I can do except following the guidlines from our government, I just lean back and relax. The published numbers don’t look bad for my country, and a side-effect of our self-isolation has been that the ordinary influenza curve is suddenly going vertical  -  downwards. We may well end up losing fewer people this year than the last, when there was no Corona around.

    Tomorrow I’ll be rounding 66. The party will be quite small  -  involving I, me and myself.

    One thing is for sure:
    We are all going to die, some day.
    I therefore take Charlie Brown’s dog, Snoopy’s approach on the matter:

    “But all the other days we are going to live.”

    I can live with that.

    Cheers,
    Arne

    This is a fairly novel event and from a scientific perspective it will be interesting to see how it evolves. My personal view is that given that we can't stop touching our faces and physical distancing will eventually have to end, is that a majority (50% ?, 70% ?) of us will eventually get COVID-19. The trick is to get it after the main outbreak has passed so that you don't have to go to an overcrowded hospital and you don't add to the current problem for others. Although it's easy to get scared, we all roll the dice when we get it, it is also true that for most of us the disease will not be much more than a modest discomfort. If we can do our best to keep the most vulnerable people in isolation for long enough, then we can get to the point where there is enough ventilators available so that even many of the people that get more serious cases will survive.

    It's easy to become paranoid about germs and surfaces. It's important to remember that there was a time before COVID-19 that we happily shook hands, hugged and didn't treat everyone like a biohazard. Although this outbreak is more serious than SARS, MERS, Bird-Flu, etc., both the trauma and many of the lessons learned from those events were soon forgotten. Please understand I'm not dismissing the experience of anyone who experienced trauma from these events, just talking about the overall human response.

    The human immune system is an amazing thing, soon most of us will have some immune resistance to COVID-19, whether naturally or potentially through a vaccine. The longevity of that immunity remains to be seen. However, the impact of a novel disease is worst during its first go through a population. I suspect by next year we will be treating novel coronavirus like the flu. For better or worse, people are remarkably good at forgetting difficult times and although there will be a challenging year ahead I suspect it will be surprising how fast things start returning to normal.

    Thanks to everyone who has foregone wages to help slow the spread of the disease. Thanks to the grocery clerks, truck drivers, doctors and nurses, who are accepting additional risk to minimise the impacts. I can't think of anyone I've interacted with on this forum that I wouldn't enjoy sitting down with for a drink and a conversation. I hope you all come through this well.

    • I have read the opposite, that  virus is transported by droplets. I base my mask on that.If that doesent work, then a surgical mask will not work either, since  double layer dishcloth had as good filtering effect (0.02 Micron objects) as the surgical facemask)
    • I don't touch anyone or anything on my way home, before I can wash my hands.
    I again stress that my focus is on not infecting others (in case I am infected) in that shop. If it doesn't work, then it doesn't do any extra harm either.

    Arne, you are viewing this from the perspective of only looking at one element of the risk.  A surgeon over a patient with an open abdomen is a totally different environment than a grocery store.   You need to look at it from a statistical perspective.

    If you are not coughing or sneezing the chance of your breath infecting anyone is extremely small.  You have the unlikely event that your are transmissible yet asymptomatic, you have the unlikely event of transmitting a droplet large enough to maintain and transmit coronavirus and you have the unlikely event that that one small rogue droplet will be encountered by another person.  A sneeze or a cough is more than an order of magnitude more than a breathing in terms of being able transmit virus.

    The mechanism for asymptomatic people transferring is through hands.  They touch their nose, mouth or eyes, then touch a surface or you.

    If you were the only one in the world wearing a mask, or you could make everyone wear a mask exactly as you do, then maybe I'd respond differently.  However, you are not significantly increasing anyone's safety while participating in a social phenomena which is demonstrably causing harm.

    Darren, 

    thanks for raising a wider view....yikes it is not easy.

    my thoughts are that you are less likely to touch  your face with a mask on, which could be the sole benefit.  Interestingly if I am out on my once a day run or cycle I don’t touch my face that much.  If I am sitting doing stuff (touched my face just now!) I do it a lot. I guess once ‘safely’ at home the risk is greatly reduced. 
    Whilst we are told not to touch our faces, I have yet to hear any advice on how to avoid doing so, any ideas? 

    We all touch our faces a lot and it is really difficult to stop doing it.  A properly worn mask will temporarily stop contact with your nose an mouth but not your eyes.  Worn improperly (which is what a majority of mask wearers are doing), it provides a great way to give you and those around you the disease.  If every mask came with some glow-powder you put on your hands, most folks would be surprised how much glow there was around their eyes, and inside their mask.   Masks are providing a false sense of security.  On your next outing watch those around you with masks, watch how often they touch their contaminated mask and then touch other surfaces. 

      I'd be willing to wager that almost all of us can't go an hour without touching our faces and most of us are likely touching our faces more than a dozen times an hour.  Given this, the solution is to wash your hands a lot.  If your hands aren't dry and uncomfortable right now you are either not washing your hands enough or you have a good supply of lanolin :-)
