Final answer:
Hepatitis A (HAV) and Hepatitis E (HEV) are the hepatitis viruses commonly transmitted via the fecal-oral route, often through contaminated food or water. HAV is generally mild and self-limiting while HEV can be more severe for pregnant women.
Step-by-step explanation:
Hepatitis A (HAV) is the type of hepatitis virus that is typically spread through feces and oral fluids. Drinking tainted water or food can expose one to this virus. It usually starts off mild and goes away on its own; most people recover in a matter of weeks to months. A vaccine is on the market and is advised for use in specific populations, such as children and visitors to regions where the virus is more common.
Hepatitis E (HEV) is another hepatitis virus that is spread through the fecal-oral route, especially in developing nations. Like HAV, HEV usually resolves on its own and does not result in long-term infection. Meat from infected animals that has been undercooked can also spread this virus. HEV poses a particular risk to expectant mothers and can be more severe in this demographic.
It is important to note that other hepatitis viruses such as HBV, HCV, and HDV are primarily transmitted through parenteral routes and not the fecal-oral route.
