    Some maths:

    The average cough has 200 million viruses. (I read somewhere...)

    Let's say that taking in a single virus carries a one in a hundred million chance of you getting infected.
    From a single cough from someone else, you unfortunately take in 10% of the viruses. So that's 20 million.
    Chance of infection is ~20%.
    If you were wearing an N95 mask, then you'd take in 1 million viruses
    Chance of infection is 0.5%
    If you make your own mask, perhaps you'll achieve 80% reduction in ingestion. Chance of infection is 4%.

    Change that one in a hundred million to one in a million and the chances of infection are:
    Unprotected: practically certain
    N95: 73%
    Homemade 80%: practically certain

    No mask will stop viruses (due to the virus size) but they will filter out dust particles and water droplets that harbour virus, therefore, it is still better to wear a mask.

    >> How big are viruses?

    I have masks and goggles but I have not yet used them. I am keeping then ready for when they are really needed.

    Some are more effective than others. This one I tried was good, but I had a bit of an accident trying to go to the loo.

    If frontline medical staff in organised countries (i.e: not here) are made to use them along with their other protective equipment then it is obvious that they work, rather than 3M profiteering.

    If you don't have some FPP3 rated facemasks then it's worth acquiring a few and using them when you shop. The sequence of events for putting it on and taking it off mean washing your hands before both actions. The people you see wearing them in the streets aren't trying to avoid infection when they're in the fresh air, they don't want to have to touch it just to queue and enter a shop.

    The surgical cloth facemasks you see are pointless and increase likelihood of catching the virus as the moisture around the mouth results in a wet area on the cloth hold the virus externally if you are unfortunate enough to walk into the path of someone with the virus who has just sneezed or coughed.

    I worked in Asia during the SARS epidemic and this changed my approach to facemasks, although I do appreciate how dystopian it makes life look. You can't even get most people to wear hats here in the UK when it's -5oC outside, unlike in Russia and China in the depths of winter at the same temperature due to worries about messing up hair styles, so I can see why many are reticent to wear a facemask. The disposable ones can be reused for up to five days if you meticulously spray them with disinfectant and ensure the valve filter is clean. Ultimately the FPP3 disposable specification is such that they are to be disposed of after 3 hours of use in high risk area, but I've (my family, I'm still isolated) donated the other hundred I had to the local NHS unit and just kept a few for each family member.

    However, viruses can easily land on your eyes and enter your tear ducts, go to your throat and down your lungs. Full filtered goggles are required.

    It only takes one virus to enter your lungs to get infected.

    If they're putting them on at home with clean washed hands then it stands to reason they'll be wearing it for the duration of their economic journey and then returning home to remove with clean washed hands.

    I haven't heard of too many people wearing facemasks here to just go a walk about the countryside or quiet areas, it's all people heading to the shops to stock up on emergency chocolate.
