[2025-10-02T00:45:36.962342] [PI reasoning] **Analyzing skin rash distributions**

I'm considering the options related to rash distributions for the conditions. Epidemic typhus and typhoid both have central distributions, while measles starts from the face and can be classified as central-ish. Secondary syphilis is unique because it includes palms and soles, indicating peripheral involvement. Therefore, I think I should choose C. I need to gather supporting evidence and references for my claims, especially for the rash distributions in these conditions.
