A viral post (and how to protect yourself)


Do you understand how viruses spread? Knowing this can help safeguard your health. That's particularly important if you want to minimise your risk in the event of a COVID-19 coronavirus or flu pandemic. It can help protect you from the common cold too.

Back in 2011 my wife and I wrote the second book in our A Vested Interest series. In it we figured out how a benign virus could be deliberately spread to infect as many people as possible in as short a time as possible. We pressured an antagonist into doing the job and carry any possible blame. Here's what he was told to do:

“We have a little task for you,” Sir Richard said. “Take these cans of antiseptic. Spray it on this cloth, and then use it in Hexham. Visit every single pub there.”
“Go to the toilets,” Lady Triplet said. “Spray the door handle or plate of each toilet and stall and give them a quick wipe. We want them nice and shiny.”
“Don’t worry, Mr. Liu,” Juanita said with mocked respect.” It won’t hurt you. In fact, it’ll do you good.”
Richard smirked. “If anyone asks, why you’re doing this, tell them you’re mysophobic, a clean freak.”
Donna softly chuckled, watching Liu flip his attention from one side of the table to the other. “Next, put on a pair of these gloves,” she said and slid a box to the end of the table. “Spray them and go shopping.”
“Visit all the supermarkets, department stores, fast food shops, everywhere you can.” John chuckled; enjoying the look of horror on Liu’s face. “Make a trip to the hospital and browse through the magazines and leaflets.”
“Be nosy,” Gary said. “Touch everywhere. Don’t forget things like lift buttons, shopping trolleys, children’s rides, handrails, touchscreens. You get the idea.”
“Why? What is this stuff?”
“Surely, you can guess, John,” Sir Richard said.

In this clip the spray Liu was given really was an antiseptic, the virus had already been released. Liu thought he would be spreading the immortality virus though.

This clip demonstrates how many corona viruses can be spread. They are not just the COVID-19 'Wuhan coronavirus' both common colds and flu are coronaviruses too. They can spread directly by droplets from coughs and sneezes but they can also be spread by contact with an infected surface. Once on your hands you can increase the chance of infection by eating, touching your lips or nose or particularly by touching your eyes. You would be surprised how often we do that without noticing it.

Time can play a big part in this. Most viruses can't survive long as infectious agents outside their host. Under ideal conditions, a damp cool surface hidden from sunlight it's possible for viruses such as these to survive for nine days outside a living host. The examples mentioned in our story are good targets for passing on infection though.

So how can you protect yourself? If you are going out shopping:
  • wear gloves. 
  • avoid touching any part of your face if you can and if you must rub your eyes then use a knuckle rather than a fingertip.
  • Wash your hands often, especially when you get home.
  • While out, use hand sanitizer. Get your children to use it also.
  • Wear eye protection of some sort.
The older you are, the more you are at risk as this image from Statista shows. For those people maybe it's time to get your groceries delivered if you can.
What about if you are younger? Can you safely risk catching Covid-19? The answer to that is still 'no'. The reason that it's so devastating to the elderly is that Covid-19 is very proficient at creating senescent cells. The common cold does this too but to a lesser extent. 'Senescent' may not be a word you are familiar with. It means 'old'. In cellular biology a senescent cell is defined as 'no longer capable of dividing but still alive and metabolically active.' These are the cells which make you age! Covid-19 (and the common cold) kills younger people but very slowly. It's the reason that the symptoms of 'long covid' are easily recognised by the elderly as, "that's how I feel." If your body is already full of senescent cells due to age then a sudden influx of extra ones can easily kill you.

What about a mask? The chances are that wouldn't be very effective. people find them uncomfortable, they feel stupid wearing them and many don't fit very well. They won't protect you from contact with an infected surface. They would be useful in preventing the spread of the virus from an infected person though. They easily catch the relatively large particles exhaled but by the time these get to you from someone else they will have evaporated enough to pass through a mask.

When the COVID-19 'Wuhan' coronavirus becomes a serious problem in your area then bear these hints in mind.

And if you want the 'Dark Secrets' book, it's available as an ebook via books2read.com/dse. It's the second book of the series. The first is available free.

Update May 2021

The #Covid19 pandemic has hit India badly and that's something which the whole world should help out with or we are in danger of an even worse pandemic.

Viruses evolve. If a person is infected with two different viruses then there is the possibility that they will merge to create a new virus. Currently in Asia there is a potentially dangerous Nipah virus spread through bat droppings and urine which can infect humans. It kills 40-45% of all those infected but it isn't passed from person to person. 

It's a matter of time before someone in India is infected with both Covid-19 and the Nipah virus. When that happens there's a chance of a new virus evolving which is spread like Covid-19 but as deadly as Nipah.

We have a good reason to be scared of this!
