• A Regional Director, WHO
• B Director General, WHO directly
• C UN Security Council within 48 hours
• D National IHR Focal Point within 24 hours ✓

Explanation

Under IHR (2005), each State Party must designate a National IHR Focal Point accessible 24 hours/day, 7 days/week for urgent communications with WHO. This Focal Point must notify WHO within 24 hours of assessing a potential PHEIC using the IHR decision instrument (Annex 2). The decision instrument evaluates seriousness, unusualness, risk of international spread, and restriction of international travel/trade. The Director General of WHO declares a PHEIC based on advice from the IHR Emergency Committee.
