For the chart of diseases, it depends on how many you had. Several tests I've had this year have asked for example diseases in a certain category, such as gastrointestinal, parasitic, or bacterial, so a quick list you can pull diseases from might help. But if you're like me and had every foodbourne illness the CDC listed, (and some they didn't ), then you can probably remove quite a few to save space. In terms of specifically environmental stuff, I've seen specific questions on Scrapie, West Nile, Asthma, and Lead poisoning. The first three were each on a different test, and each test asked extremely specific questions about them - not just symptoms, but famous studies done around them, an air quality index for asthma, etc. Lyme disease, tetanus, and other vectorbourne or parenteral infections will probably feature as well in later tests.Last year, I had a chart with food bourne illnesses, symptoms, incubation periods, and such, on my notesheet. Because this year's focus has changed, should I remove them? And also, what should I add to be prepared for environmental quality-based disease questions? I'm looking for specifics, such as Asthma, West Nile, and so on.
On another note, has anyone read "The Ghost Map"? It's an excellent book about the 1854 London Cholera outbreak with John Snow and Henry Whitehead investigating. Probably not great for the purposes of S.O., but an awesome read.
