As measles is highly infectious through airborne transmission, other secondary cases may occur in susceptible people. Measles has an incubation period of between seven and 18 days (average 14 days from exposure to rash) so should be considered in the differential diagnosis of any susceptible person who presents with a compatible illness, with an onset date between 10 March and 28 March 2018.
