What type of disease does rotavirus primarily cause in children?

• A. Respiratory illnesses
• B. Diarrhoeal diseases
• C. Skin infections
• D. Ear infections

Answer: (B)

Rotavirus primarily causes diarrhoeal diseases in children. It is a highly contagious virus that infects the intestinal lining, leading to severe dehydration due to excessive vomiting and diarrhea. This is particularly significant in infants and young children, who may not yet have developed immunity to the virus. In many cases, the symptoms can be quite severe, resulting in hospitalization if not managed properly. Vaccination has been a key public health measure in reducing the incidence of rotavirus infections and the associated burden of diarrheal illness in children worldwide. The other options either pertain to different body systems or are caused by different pathogens and do not directly relate to the primary effects of rotavirus infection.
