طفل عنده جديري مائي. متى يصبح غير معدٍ ويرجع للمدرسة؟

When is a child with chickenpox no longer infectious and able to return to school?

1. When all blisters have dried and crusted
2. One day after the rash appears
3. After the first antipyretic dose
4. Once the fever settles only

Answer: A) When all blisters have dried and crusted. Chickenpox is contagious from 1–2 days before the rash until all lesions crust (about 5–7 days). Aspirin is avoided and nails are kept short.
