Q: What makes hepatitis B infection in infants particularly concerning?

A. Infants rarely have symptoms.
B. Infants are at increased risk of becoming chronically infected.
C. Both A and B.
D. None of these.

The correct answer is C. Both A and B.
Many infants infected with hepatitis B do not show symptoms, and therefore are not diagnosed. However, about 90 of 100 people infected with hepatitis B as an infant will have chronic, lifelong hepatitis B infection. Similarly, 30 of 100 children infected with hepatitis B between 1 and 5 years of age will be chronically infected. In contrast, only about 2 of 100 infected adults will be chronically infected.
