What’s up with viruses? What the hell are they, anyway? And how do those sly whatsits operate? Here’s a layperson’s guide.
Disclaimer first: I’m not a doctor, nor do I play one on TV. I’m not a microbiologist and I don’t think anyone plays one on TV. I’m simply a person who stayed awake in science class and has read a lot ever since.
First, let’s make this clear: Viruses have no brains. We can talk about a virus’s goals or intentions or strategies, but we’re at least partly anthropomorphizing or speaking metaphorically. A virus is a strand of DNA or RNA (in the case of COVID-19) wrapped in a shell which can glom onto bodily tissues so the virus can duplicate itself and move on to another host.
That’s what it does, and that’s about all it does. All a virus wants is to replicate itself and continue to do so. The fact that it makes you sick is quite incidental to that.
The incubation period – the length of time before you show symptoms of an illness – is important. It gives the virus time to multiply unnoticed within the body and infect others via bodily fluids before someone notices and tries to kill it off. The longer the incubation period, the more successful the virus is. Think HIV. It has an incubation period of years, which was what allowed it to be so successful at infecting a large number of people before anyone noticed.
The incubation period for coronavirus is, we think, about two weeks, give or take. You could have the virus without any symptoms during that time and all the while be spreading it by coughing, poor hygiene, or being too close to people. The masks that you wear may seem like they are protecting you, but actually they are preventing you from making other people sick.
Viruses are tricky bastards. They can – and do – evolve and mutate and jump species. That’s when a virus becomes particularly dangerous. If it mutates, as the flu virus does pretty much every year, no one has a natural immunity to it and unless a vaccine is created for that specific version, a lot of people get the flu.
Jumping species is another thing altogether. A virus can be living happily in a pig or a chicken or a bat or a monkey, not causing too much damage (at least not right away). But when a virus mutates so that it can infect and cause illness in another sort of animal (for our purposes, a human being), that’s when things get really tricky. The virus now has a population to infect that never encountered it before. It can burn through that population like wildfire. If the incubation period is short, the virus may burn itself out rapidly and not claim too many victims, as they die before having a chance to pass it on. But if the incubation period is longer, the virus gets a free ride to any number of new hosts.
And yes, people can get infected by eating the host animal. It’s not very likely, since most people eat their meat cooked, not raw. Bodily fluids and bites or scratches are much more dangerous, as is contamination with feces. But that’s not the only way that viruses are transmitted via animals. You know how viruses are passed from person to person without us having to eat each other’s flesh? Well, the virus can travel in the bodily fluids of other animals as well. So if you don’t wash your hands after feeding your chickens, or you stir up and breathe in some bat guano while you’re exploring a cave, or a mouse pees in your storeroom, any viruses lurking there can infect the unwary, if that virus is ready to jump species.
So, that’s a basic guide to viruses. And let’s be real about this. Viruses are all around us and spread quite naturally. There’s no real need to worry about a virus being manufactured and escaping from a lab. And need I say that Hillary Clinton, the deep state, Chinese supervillains, and George Soros have nothing to do with it? Yes, I suppose I do.
Right now there are a lot of blog posts that tell you how to get through this period when we are plagued with COVID-19, the coronavirus. There are helpful patterns for sewing masks. There are recipes to try and games to play to while away the time spent in self-isolation. There are exhortations to take up a new hobby or learn a new language or just take care of yourself – your mental and physical health. There are also entertaining conspiracy theories for the origin of the virus, which seem to involve germ warfare, Hillary Clinton, bats, the Deep State, and the elections. (Personally, “bats” is the word that comes to my mind to describe these theories.) There has even been a virtual science fiction convention online that has been running for weeks instead of just for the usual weekend.
Let’s say you have five people in your family and another five who are close friends. Or four and six – enough to make up ten people in your life, anyway. Statistically speaking, two of those people will experience mental illness at some point in their life. Or the person experiencing mental illness could even be you. The National Association for Mental Illness (NAMI) reports that one in five – or maybe even one in four – people will experience mental illness. That’s 20% to 25% of Americans.
I saw a meme the other day that defined the laundry cycle as wash, 45 min.; dry, 60 minutes; fold and put away, 7-10 business days. That would be optimistic for me and my husband. We are useless people.

Then came the year when my sister and I had to grow up fast.
Other things we do for cats are less ridiculous. My husband and I, and a number of people we know, have been trained and trusted with our cats’ medical procedures. Most people can give pills or liquid medicines, eye drops or ear drops at home. (Although even these duties are not for the faint of heart. One of our cats invented the sport of projectile drooling when given a pill.)
We can’t do much about educating and informing the adult population that all those beliefs are false. But we can avoid raising another generation that buys in to these misconceptions – if we start now with mental health education in schools.
