Classic Measles Presentation (for Quick Reference)

• Incubation: 7–14 days (avg 10–12)
• Prodrome (2–4 days): High fever (often >104°F/40°C), cough, coryza, conjunctivitis (“3 Cs”)
• Koplik spots: Tiny white lesions on buccal mucosa (pathognomonic), appear 1–2 days before rash
• Rash: Maculopapular, starts face/hairline → spreads downward → fades in same order. Lasts 5–6 days.
• Complications: Otitis media, pneumonia, encephalitis (1/1000), SSPE (rare, fatal, years later)

Action Steps

• If measles suspected: call ahead before visiting clinic/ER to prevent exposure.
• Isolate immediately (airborne precautions).
• Confirm with PCR (throat/nasopharyngeal swab) and serology (IgM).
• Report to local health department (mandatory in most jurisdictions).

Vaccination (MMR) remains the most effective prevention: 97% effective with 2 doses.
