Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

INFECTIOUS DISEASE

YEAR 2 | PAGE 25E - SYNDROME-BASED DIAGNOSIS + CLINICAL INFECTIONS

INFECTIOUS-DISEASE REASONING FRAME

SYNDROME/SITE -> HOST + IMMUNE STATUS -> EXPOSURES + TRANSMISSION -> LIKELY PATHOGENS -> SPECIMEN/TEST -> EMPIRIC THERAPY -> NARROWED THERAPY -> PREVENTION/ISOLATION. Start with the syndrome, not an organism list.

- For fever plus a focal syndrome, generate 3-5 likely pathogens from site + host + exposure before looking at choices. - Choose the highest-yield specimen and test: culture, NAAT/PCR, antigen, serology, microscopy or imaging - and know when treatment cannot wait. - Distinguish colonization/contamination from true infection using symptoms, source quality, inflammatory response and repeated/confirmatory evidence. - For each syndrome, state empiric coverage, the data that permit narrowing, and the prevention/isolation step that changes transmission risk.
