Which is a cause of acute infectious infantile diarrhea?

• A. Rotavirus
• B. Norovirus
• C. Adenovirus
• D. Astrovirus

Answer: (A)

Rotavirus is the leading cause of acute infectious diarrhea in infants. It spreads easily through the fecal-oral route and typically produces a sudden illness with profuse watery diarrhea, vomiting, and fever, which can lead to dehydration in young children. Because infants have high vulnerability to dehydration, rotavirus infections are especially clinically significant, and vaccination has greatly reduced their impact in many places. While other viruses such as norovirus, adenovirus (types 40/41), and astrovirus can also cause gastroenteritis in children, rotavirus remains the most characteristic and prevalent cause of acute infectious diarrhea in infants.
