Animal bites are considered dangerous because of the possibility of infection or the transmission of:

A) HIV
B) Lyme disease
C) rabies
D) hepatitis

Rabies is the primary concern with animal bites due to its high fatality rate once symptoms appear. Lyme disease is transmitted by ticks, not through animal bites directly. HIV and hepatitis are primarily spread through blood-to-blood contact, sexual contact, or from mother to child during birth, not typically through animal bites.
