Health and Medicine, an easy guide to infectious diseases, chronic conditions, and health policy

Health information is everywhere, but very little of it says which part applies to you. Here we organise infectious disease, chronic conditions, food and drug safety, health insurance and public health policy around concrete cases.

We cover disease surveillance such as Ebola and foodborne illness, conditions that need managing for years like chronic kidney disease, diabetes and hypertension, food labelling standards such as decaf claims, and policy shifts like health insurance fee reform that land directly on what you pay at the clinic.

What we write here is meant to help you understand, not to replace diagnosis or treatment. Knowing the numbers and the terms in advance makes the few minutes you get with a doctor go much further.
