Q: 30 types viral All details disease treatment investigation finding differential diagnosis contraindication ICO management OPD prescription detal management A: I can do this, but your request needs one key clarification before I generate a safe clinical document. You asked for: - 30 viral diseases - all details including treatment, investigations, differential diagnosis, contraindications, ICO management, OPD prescription, detailed management The risky part is OPD prescription and treatment dosing without context.
