An unvaccinated 3-year-old has had high fever, cough, coryza and red eyes for 4 days, then a rash spreading from the face downward and white spots inside the cheeks. What is most likely and which precaution?

1. Chickenpox; droplet isolation only
2. Measles; airborne isolation
3. Drug allergy; no isolation needed
4. Scarlet fever; contact isolation only
