🔑 Key Concepts & Definitions

• Measles (Rubeola): A highly contagious viral infection caused by the measles virus, characterized by fever, cough, coryza, conjunctivitis, and a distinctive exanthem.
• Exanthem: A widespread rash that appears on the skin as a symptom of infectious diseases, often preceded by prodromal symptoms.
• Koplik Spots: Small, white, bluish-gray lesions with a red base found on the buccal mucosa, considered pathognomonic for measles.
• Prodromal Phase: The initial phase of measles, lasting 2-4 days, featuring fever, cough, coryza, and conjunctivitis before rash onset.
• Rash (Measles Exanthem): A maculopapular, erythematous rash that begins on the face and spreads cephalocaudally and centrifugally.
• Complications: Severe outcomes such as pneumonia, encephalitis, and secondary bacterial infections, especially in immunocompromised or unvaccinated individuals.
