Final answer:
Hepatitis A and Hepatitis E are transmitted primarily through the fecal-oral route, with vaccines available for Hepatitis A and both types generally being self-limiting.
Step-by-step explanation:
The hepatitis that is acquired primarily by the fecal-oral route is Hepatitis A and Hepatitis E. These viruses are commonly transmitted through ingestion of contaminated water or food, and close personal contact.
Hepatitis A usually resolves on its own within a few weeks to months, and there is a vaccine available for prevention. Hepatitis E can also cause outbreaks and is typically self-limiting. However, genotype one of HEV can cause person-to-person transmission and is considered a risk especially in pregnant women and in developing countries.
