Correct answer: C — Notify the local public health unit and isolate the child

Measles is a notifiable disease in Australia. Immediate notification to the local public health unit is mandatory for case investigation and contact tracing. The child should be isolated (airborne precautions) for at least 4 days after rash onset. Post-exposure prophylaxis (MMR vaccine within 72 hours or immunoglobulin within 6 days) should be offered to susceptible contacts.
