Correct answer: E — Isolation with urgent measles vaccination campaign

Isolation with urgent measles vaccination campaign is the single best answer because measles is highly transmissible and requires isolation, case notification and rapid vaccination of susceptible groups. Mass azithromycin for cholera is plausible in a related presentation, but it is less appropriate because it does not fit the key discriminator in this vignette. The teaching point is that vitamin A should also be given to affected children where indicated.
