Correct answer: A — Isolate, notify public health and send measles PCR/serology

The clinical syndrome is measles, requiring airborne isolation, urgent public health notification and confirmatory testing. Antibiotics do not address measles and childcare attendance would risk transmission. The pearl is that measles is infectious before rash onset, so contact tracing and post-exposure prophylaxis decisions are time-critical.
