Good, bad and terrible news.
Protecting Others
Take a look at this picture:
Wearing a mask over your nose and mouth WILL help stop you infecting others with Covid-19, colds and flu but you probably don't need to wear one if you can keep 2 metres away from them outside.
Now I have to admit it's not a real picture. It's cobbled together from different images to illustrate a point. Look closely and you'll see tiny droplets of spittle from the shouting man. We probably all know that these droplets are produced when we sneeze or cough. We probably all know that 'coughs and sneezes spread diseases' too. BUT it's not just those who cough and sneeze that produce these infective droplets. We all produce them when we shout, sing, talk, breath heavily (think joggers) or even breath normally. This means if you are asymptomatic - are infected but show no signs of it - you can spread the disease without knowing it and this disease can kill people! Are you OK with killing others?
Stay away from crowds, especially those where people are shouting and singing. Joining a protest against mask wearing is the height of stupidity.
This is where wearing a mask helps. It traps any of these infected droplets and stops others from catching it from you. If you are near others then wearing a mask, even a cloth over your mouth, can prevent the infection spreading.

Do masks protect YOU?
A simple cloth mask is unlikely to offer much protection to the user.
A mask with an exhalation vent may give the user some slight protection but won't help others.
A medical N95 mask, the right size and properly fitted may offer some slight protection (up to 5%) to the user and others.
ANY mask is better than no mask.
Some people might tell you that the virus is tiny compared to the gaps between the mask fibres. The virus can easily pass through these gaps. It's a bit like trying to keep mosquitoes out using chicken wire. That's true. However a better analogy is that chicken wire will keep mosquitoes riding on the backs of chickens IN! The virus is carried in water droplets and these are much bigger than the mask fibre gaps causing them to be trapped. There's also an electrostatic charge between mask fibre and droplet, causing the droplets to be drawn to the fibres.
On a cold calm day you'll become aware of the droplets we breath out. You see a mist from your breath. It rapidly evaporates though and you won't see it spread beyond that two metre distance. Once the droplets evaporate any virus carried in them is no longer able to infect you. It needs that moisture to remain infective.
Buy at least five N95 (or KN95) masks. If you can, avoid those made in Asia since they are probably made to fit Asian faces which tend to be flatter. Your mask should have a metal strip at the top which you can shape to your nose. The best ones have three layers and the outer layer will be water resistant. Some have a soft plastic strip inside at the top which acts to help seal the gap around your nose. The straps should not be too tight or they will distort the metal strip over your nose and allow exhaled air to leak. They will also irritate your ears. If your mask steams up your glasses then it's not properly fitted.
Dust masks will help protect others but not those masks which have an exhalation vent.
You can make your own masks which will certainly help prevent spreading the virus and might help you, if made properly. Spray the outer layer with a water repellent solution but not the inner layers.
How do you wear a mask properly?
- Wash your hands before putting it on or use hand sanitizer.
- Metal strip at the top.
- Place the mask over your nose and mouth then loop the straps over your ears.
- Using both hands at the same time mould the metal strip over the bridge of your nose. The straps should not stretch this strip out of shape. If they do, consider extending them somehow.
- Add glasses or safety glasses over the top of the mask. If the glasses fog up then consider using an anti-fog spray from an optometrist or washing the glasses in soapy water then allowing them to air dry. Rubbing shaving cream into the surface of the glasses until you can no longer see it can help but I'm not sure how this will affect any coating on the glasses.
- Use the mask when you are out and in contact with other people. Remove it when you are alone, in your car or at home.
- If you are outside and able to stay at least two metres from other people then there is no point in wearing a mask.
- If you find breathing difficult when mask wearing - slow down. The first signs of difficulty are finding yourself breathing through your mouth.
Can I re-use a mask?
The virus is inactivated if it is allowed to dry out. Detergents will destroy the virus. YES you can re-use a mask.
- If your mask is home made then wash it after each use and by all means re-use it. You probably can't wash bought surgical masks.
- When you have used a bought mask, let it dry for at least three days before re-using it. You can re-use masks described as 'single use' provided you are not someone like a doctor or nurse in constant contact with patients. Drying masks in sunlight works but glass windows filter out the sun's UV rays which kill the virus.
- Drying a mask using silica gel drying packets with mask and drying agent in a sealed plastic bag works well.
Yes! But you have to act wrongly:
- Don't use the same mask again and again without washing it or drying it. Doing so will encourage the growth of mould and you don't want to breath that in.
- Loose in a pocket is not the best place to keep a mask for use. You should store masks in a sealed plastic bag with a small silica gel drying pack.
- Don't wear a mask for too long. If it gets damp, replace it. Certainly replace it after two hours.
- Don't rush around while wearing a mask.
You don't need to worry about these two myths:
- Wearing a mask and oxygen starvation.
- Wearing a mask and carbon dioxide poisoning
Remember that chicken wire argument? The size of oxygen and carbon dioxide molecules are REALLY tiny compared with the mask fibre gaps. They are microscopic compared with the virus particle size and they are not carried in water droplets. Both can easily pass through a mask. If you don't feel you can get enough air - slow down.
What other steps can I take to protect myself?
- Wash you hands often. If you can't do that use an alcohol based hand sanitizer 65% to 70% alcohol works best. 100% alcohol (meths) and alcoholic spirits such as vodka don't work.
- Wear glasses or some eye protection. Your eyes are protected by very thin membranes which are vulnerable to viral infection. Ever notice a cold can make your eyes sore?
- DON'T touch your face while out. Easy to say but not easy to do. We normally constantly touch our faces to make ourselves feel secure psychologists say. Most times we are not aware of this. Wearing gloves and glasses can help break the habit, so can wearing make-up. If you simply MUST scratch that itch use a knuckle rather than a fingertip.
- Wear gloves. They act as a barrier between you and things other people have touched. That includes door handles, shopping cart handles, buttons, magazines, books, money. After wearing gloves remove them without touching the palm side of the glove and either wash them or leave them in a sunny place to dry out. I personally wear Dex-fit gloves which are plastic coated on the palm side only. They can be sanitized and will work with touch screens usually. They are available in multiple sizes from Amazon in the UK and US
- If you have long hair fasten it up and consider wearing a hat.
- When you return from shopping wipe over metal and plastic coated products with a disinfecting wipe. Paper and card objects will probably be OK by the time you get them home. Then wash your hands.
- After shopping, if you are really paranoid, take a shower and wash your hair and clothes.
What symptoms can I get if I am infected with COVID-19?
According to New Scientist it's not just a matter of a cough, fever and difficulty breathing.
- You may have no symptoms at all yet still be able to infect others.
- You probably (but not always) will get a persistent dry cough.
- You probably will develop a fever.
- You may be sneezing.
- You may lose your sense of taste and smell.
- You may suffer from exhaustion, numbness or diarrhoea
- Some people have excessive weight loss (but it's not a good way to diet)
- Some people complain of brain fog.
- Muscle pain seems fairly common
- In many cases people develop rashes
- In a few people there are hallucinations. It appears that this virus can cross into your brain.
- It can cause lung failure but also heart attacks, strokes, kidney damage and other conditions involving blood clots.
- Whilst most people can shrug off many symptoms in about two weeks there are uncomfortable symptoms which can last many months. We term this 'long covid.'
And finally the good and bad and terrible news
The good news is that unlike the other corona viruses, colds and flu, the vaccination against covid-19 seems effective at preventing death from it. You may still catch it and may still spread it by not wearing a mask. You can be re-infected. It's early days to tell that for certain though.
More good news is that the research done on preventing SARS, MERS and Covid-19 may eventually lead to a vaccination against all the corona viruses - that includes the common cold!
The bad news is that although it first appeared that the elderly and those with pre-existing medical conditions were worst affected there are now many cases of young, healthy people who have either died or been left with failing hearts, lungs, kidneys or other organs. Unlike flu this virus seems quite happy to spread during the summer months.
The terrible news is something that science has known for a while. All viruses cause harm. The cells of your body they kill will usually be replaced. Some cells survive with damaged DNA and as you accumulate more of them these cause you to age. This means that even 'mild' diseases such as the common cold are killers! They simply take many years to kill you through an uncomfortable way called aging. Have you noticed how the symptoms of 'long covid' are very similar to the symptoms those 'getting old' experience?
If everyone wears a mask, that will help prevent the spread of Covid-19, colds and flu.
| Where did all this come from? Back in 2007 my wife and I were doing research for a novel 'Immortality Gene'. We explored science journals for how different viruses spread and what their long term effects were. We explored how a virus could be used for gene therapy. In the process we learnt what could be done to protect ourselves from colds and flu. I started shopping at quiet times during the night. I wore gloves and glasses. I used hand sanitizer. We didn't catch colds or flu. With COVID-19 we put our experience to use again. This time we could wear masks since it became socially acceptable to do so. We hope you find this information of use and if you want to repay us, download a FREE copy of our book Immortality Gene. It's the first book of a series. It's long and it has been a #1 top technothriller at Amazon. |
