Which statement about Hepatitis A (HAV) is correct?

• A. It has a vaccine available.
• B. It causes chronic infection in all cases.
• C. It is only transmitted through sexual activity.
• D. It primarily spreads through sharing needles.

Answer: (A)

Hepatitis A (HAV) is indeed associated with a vaccine, which is designed to provide immunity against this particular virus. Vaccination is a critical tool in preventing the spread of HAV, especially in populations at risk or in outbreak situations. The vaccine is usually recommended for travelers to areas where the virus is more prevalent, as well as for individuals who are in close contact with someone infected, or have certain lifestyle risk factors. The other statements do not accurately describe Hepatitis A. It does not cause chronic infection in most cases; instead, HAV typically results in an acute, self-limiting illness. It is also not exclusively transmitted through sexual activity, as it can be spread through fecal-oral routes such as contaminated food or water, making it more broadly transmissible than other types of hepatitis that may be linked to sexual contact. Finally, while sharing needles is a significant transmission route for Hepatitis B and C, it is not a primary mode of transmission for HAV. Understanding these details helps illustrate the role of vaccination as a necessary preventive measure against Hepatitis A.
