There is a lot more there after that.Keith Baker at keith-baker.com wrote:Dragonmarks: Modern Medicine
Could there be a pandemic in Eberron? A plague spread by the Children of Winter, or a bioweapon created by the nosomantic chiurgeons of House Jorasco? How does disease even work in a world where lesser restoration can remove any disease? Given events in our world, these things are on my mind and I thought I’d tackle them with a series of articles. This post will take a quick look at medicine in the Five Nations; a follow-up article will explore the role of disease and plagues in campaigns.
Health and Healing
Fifth edition presents a largely abstract view of health. As I’ve mentioned before, hit points are a very nebulous concept—a blend of actual physical health and luck, skill, or willpower. A character can regain hit points by spending hit dice during a short rest, and is fully restored after a long rest. When you use the Medicine skill, all you need to do is role a die. But remember that when we play D&D, we are building a story together. The rules provide a foundation for that story, but it’s up to the DM and players to add the details. MECHANICALLY you’re as good as new after a long rest, and you don’t have to do anything other than hang out for eight hours to get that benefit. But if there’s a character with the Medicine skill in your party, you might tell the story of how that character worked to patch you up during that long rest—how they had to stitch up a particularly deep wound, how they gave you a shot of Irian-infused water to keep you on your feed or rubbed a Mabaran salve on your arm to numb the pain. When someone uses the Medicine skill or an herablism kit, they or the DM can DESCRIBE them as using medical tools or techniques, even if all the PLAYER does is roll a die. The point is that the rules keep things simple; we don’t WANT player characters to spend a long time sitting on the sidelines recovering from a sprained anchor or a broken rib. But you can DESCRIBE that process of recovery in as much detail as you want.
I don't think I've ever put that much thought about disease into a game, but it does sound like a way to go beyond the d20 rolls (if you have a PC doing that stuff).
