A patient 12 months old comes with his father for evaluation. The father reports fever and dry cough while they were on vacation. What is the FIRST appropriate management?

Correct answer: D. Isolate both the father and child

• A. Incorrect. Proceeding with dental treatment on a potentially infectious febrile child risks cross-contamination in the dental office.
• B. Incorrect. Referral to a specialist is not the first immediate step in managing a potentially infectious patient in the dental office.
• C. Incorrect. Providing masks is a partial measure but does not address the potential infection control breach already created by having them in the waiting area.
• D. Correct. A child with fever and dry cough (potentially infectious respiratory illness) should be ISOLATED from other patients and staff. Isolation prevents potential spread to other patients. After isolation, assessment determines if treatment should be deferred and whether emergency medical referral is needed.
