According to WHO/UNICEF, what zinc regimen is recommended for acute diarrhea in children?

• A. 20 mg per day for 10-14 days
• B. 10 mg per day for 5-7 days
• C. 30 mg per day for 7-10 days
• D. 15 mg per day for 14 days

Answer: (A)

Zinc given during an episode of acute diarrhea helps shorten the illness and reduce the risk of future diarrhea by supporting intestinal function and immune response. The World Health Organization and UNICEF guidelines specify a daily dose of 20 mg of elemental zinc for 10 to 14 days in children older than six months (and 10 mg daily for 14 days in infants up to six months). The regimen described in the question—20 mg per day for 10–14 days—follows this guidance. The other options differ either in dose or duration and do not match the recommended WHO/UNICEF regimen.
