Which is a common source of hepatitis A infection?

• A. Inhalation of airborne particles.
• B. Contaminated food and water.
• C. Direct contact with animals.
• D. Receiving a vaccine.

Answer: (B)

Hepatitis A is transmitted mainly through the fecal-oral route, so people become infected by ingesting food or water contaminated with the virus, or by close contact with an infected person where hand hygiene is poor. This makes contaminated food and water the most common source of infection. Inhalation of airborne particles isn’t how hepatitis A spreads, since it isn’t an airborne virus. Direct contact with animals isn’t a typical source for HAV, which mainly passes between humans. Receiving a vaccine isn’t a source of infection either; the vaccine is used to prevent hepatitis A.
