Which group is most likely to be infected by the Hepatitis D virus?

The Hepatitis D virus requires the presence of the Hepatitis B virus to replicate and cause infection. Therefore, individuals who are already infected with Hepatitis B are the primary group at risk for contracting Hepatitis D. This relationship is crucial because without Hepatitis B, Hepatitis D cannot establish an infection.

Individuals not vaccinated against Hepatitis A, those with any viral infection, and those who have contracted Hepatitis C may have health risks, but these groups do not have the necessary co-infection dynamics that facilitate the transmission and infection of Hepatitis D. Understanding the specific relationship between Hepatitis B and D is essential for identifying the most at-risk populations.
