Which infection is viral?

Which infection is viral?

• A. Gonorrhea
• B. Chlamydia
• C. Hepatitis B
• D. Bacterial vaginosis

Answer: (C)

Pathogens causing infections come from different families, mainly bacteria, viruses, fungi, or parasites. This question asks which infection is caused by a virus. Gonorrhea and Chlamydia are caused by bacteria, as is bacterial vaginosis, which is a disruption in the vaginal microbial balance rather than a viral infection. Hepatitis B, on the other hand, is caused by a virus, making it viral. This distinction matters because antibiotics target bacteria, while viral infections like hepatitis B require antiviral approaches and vaccines for prevention.
