One often hears some version of, "If they can send a man to the moon, why can't they cure the common cold?" Well, for starters there are probably 200 or so different versions of "the" common cold, so you'd need 200 cures. They are all viruses, which scientists put into several groups, including the Rhinoviruses (the most common), and Coronaviruses, also known as Covid.
Symptoms vary but all include sniffling and aching and maybe running a fever. One's body does build up immunity, so by the time a person has been around for a while they don't catch nearly as many colds, as they've already had and recovered from a large proportion of them. Children, as every daycare knows, catch lots of colds, because their immune system is still developing and is meeting colds for the first time. Influenza is another viral disease, again with a number of different strains, potentially more deadly than a cold and usually not involving sniffles, though it can make a person feel terrible otherwise.
In spite of the name, you won't "catch cold" by going outdoors without a sweater. But the cells in your nose that fight off foreign invaders (like viruses) may be less effective when they're chilly, making colds spread more readily, especially when people are mostly indoors during the winter months, breathing each others' air.
(Don't try to treat viral diseases with antibiotics. Antibiotics are effective against living creatures like bacteria, which viruses are not, and overuse of antibiotics helps antibiotic-resistant bacteria to develop. This health tip brought to you courtesy of this blog.)
Wait, you say, didn't you just mention Covid a couple paragraphs back? What's with that? Yes indeed, I did, because Covid-19 is a Coronovirus, related to though a lot more serious than the "common cold" versions. It's called "19" because it was first identified in 2019. (The number has nothing to do with the number of pounds you gained in 2020, staying home, getting no exercise, but filling your time baking sourdough bread and cinnamon rolls.)
But what, you say, does this have to do with the Middle Ages? You're about to find out.
Some version of "the common cold" has been around for a long time, the sniffles being described by physicians in ancient Egypt. But there is emerging evidence that one of the Coronovirus versions of the cold first appeared in humans in the thirteenth century. Like many viruses (including Covid-19), it probably developed first in animals and then made the jump to humans.
It was a killer. A lot of people got very sick and died. It was not nearly as bad as the Black Death in the fourteenth century, but it was bad. Without modern vaccines, people had to rely on their own immune systems and on friends and family keeping them warm and fed. This is when it became a great act of charity to endow a hospital, to care for the sick and the indigent.
This disease was probably comparable in effect to modern Covid-19, and like Covid-19 it mutated readily, each iteration being somewhat less deadly but somewhat more infectious. It seems most likely that this medieval form of Covid, now just starting to be studied seriously by historians of medicine, is still with us. We know we still have a version of Covid that killed a lot of people in Russia in the 1890s, before becoming less deadly. So it seems Covid-19 is going to be with us permanently, in some form.
By the way, there are a number of "just so stories" about medieval people, some of which involve colds and are clearly untrue. No medieval priest taught that your soul would escape as you sneezed or coughed, or that the devil would zip into the vacancy your soul left behind. So stories that people said "Bless you" to encourage your soul to stay put, or that they coughed into a handkerchief to keep the soul from escaping, are just untrue. People have doubtless said some version of "Bless you" or "Gesundheit" (meaning Good Health) as long as people have sneezed, because sniffles are an illness you hope the person recovers from. And they coughed into handkerchiefs because, even without knowing about viruses, no one likes a sick person spraying on them.
