Happy Birthday, Epidemiology!

There was a time not so very long ago in human history when we believed that miasmas (bad air) caused illness. Doctors didn’t even wash their hands between seeing patients because how could gentlemen be responsible for spreading illness?

There were no microscopes, so no one could look and see bacteria doing battle with our own immune system. People could only know what they observed and what they observed was that the areas where disease was most prevalent were also very smelly from the dead and dying people.

We know now, of course, that the smell so common in areas where poor people lived wasn’t the cause of their illness, but another product of the things making them sick. Bodies and human waste (lots of poo) left in the streets, rotting food, animals and humans living in close proximity, sewage in the water. Germ Theory tells us that these things become the breeding grounds of virus, bacteria, fungi, and other tiny critters which make us sick. By eliminating those risks from our environment, we eliminate a lot of the pathways those germs take to making us ill.

When Poor Air Quality Strikes: Keeping Safe When It Snows Ash

The air over Seattle (and the rest of the Pacific Northwest) has been very poor lately. The concentration of PM2.5 (very small bits of particulate matter in the air) has been well above what health officials consider acceptable for human health. The situation is even worse up north in Alberta when the sky seems to be permanently yellow like a scene from some kind of post-apocalyptic dystopia video game my partner would play.

There's been a lot of worry for what the air quality means for our health and why it's happening, as well as the completely understandable fear that this is our new normal. I'm going to talk a bit about what's in the air, who is at risk of poor health from it (spoiler: everyone), and some ways that you can try to keep yourself and your family healthy when these events happen.

It's Just Food Poisoning

When I think of food poisoning, I often think back to President Josiah Bartlet calling the Butterball Hotline after Toby Ziegler warned him that cooking the stuffing in his Thanksgiving turkey would make his guests ill (and possibly kill them). President Bartlet is surprised by this and has a series of ridiculous interactions with his staffers trying to track down the truth of the matter before finally receiving some excellent advice from the Butterball Hotline.
