Transmission: Airborne and respiratory
Reservoir / vector: Humans are the only reservoir.
Incubation: Usually 7 to 14 days from exposure to rash onset.
Severity: Can lead to pneumonia, encephalitis, and death, especially in under-immunized populations.
Diagnostics: PCR and serology, paired with travel and exposure tracing.
Treatment: Supportive care; vitamin A is relevant in specific clinical settings.
Prevention: Two-dose measles vaccination and rapid outbreak control around exposed contacts.

Why this keeps becoming news: Measles is a clean reporter desk disease because it reveals vaccination gaps, school and household spread, travel-linked importation, and public-health capacity all at once.
