Rotavirus Diarrhea: if one is exposed to Rotavirus, the person suffers from diarrhea. Vomiting and fever are the starting symptoms and then followed by 3 to 7 days of watery diarrhea. It can cause abdominal pain and other intestinal symptoms. It is highly contagious that causes severe diarrhea in young and infants. Other causes of diarrhea can be adenovirus, bacterial infection, allergies, medications, poor absorption, radiation therapy, Norwalk virus, etc.Studying the graph, the blue line shows diarrhea caused by all the possible causes including Rotavirus. In contrast, the green line shows average with years, and the orange line shows diarrhea caused by only Rotavirus, not other causes involved, as mentioned in the image. It can noted that a large portion of diarrhea admission is because of Rotavirus represented by the orange line in the graph. So the answer is A the orange line is only for Rotavirus.
