Step 1: Understanding the Question:
The question asks for the standard therapeutic dose of Zinc used in the management of pediatric diarrhea, as recommended by WHO and UNICEF.
Step 2: Detailed Explanation:
• Zinc supplementation is a critical intervention during diarrheal episodes because it helps the intestinal mucosa recover faster and boosts the immune system.
• The standard international recommendation for children over 6 months of age is 20 mg of elemental Zinc per day for 10-14 days.
• For infants under 6 months, the dose is 10 mg per day.
• Using Zinc alongside Oral Rehydration Salts (ORS) significantly reduces the duration and severity of the illness and prevents future episodes for the next 2-3 months.
• It is a low-cost, high-impact public health measure implemented in most developing nations.
Step 3: Final Answer:
The recommended dose is 20 mg.
