Which hepatitis type is transmitted via fecal/oral route and is vaccine-preventable?

• A. Type A
• B. Type B
• C. Type C
• D. Type D

Answer: (A)

Think about how the virus spreads and whether there’s a vaccine against it. Hepatitis A is transmitted by the fecal-oral route, often through contaminated food or water, and there is an effective vaccine available to prevent it. That combination—fecal-oral transmission and vaccine preventability—makes it the best answer. The other hepatitis types spread mainly by other routes (for example, blood or body fluids) and, while some have vaccines, their typical transmission isn’t fecal-oral, so they don’t fit both criteria as cleanly.
