Final answer:
The Hepatitis E virus (HEV) is self-resolving but can be particularly fatal for pregnant women. HEV is transmitted mainly through contaminated water and food. While there is no specific vaccine for HEV, the HAV vaccine may offer some protection.
Step-by-step explanation:
Which Hepatitis virus is typically self-resolving but can be fatal in pregnant women? The Hepatitis E virus (HEV) is typically self-resolving within one to two weeks, and in most cases, does not cause chronic infection. However, it can be fatal for pregnant women, especially during the second or third trimester, due to the risk of acute liver failure. HEV is generally transmitted through the fecal-oral route from contaminated water or food, and in some regions, through undercooked meat from infected animals. While HEV infections are rare in the United States, pregnant women are at particular risk with this virus, which has a high mortality rate for this specific group. Precautionary measures, such as consuming well-cooked food, practicing good hygiene, and ensuring safe drinking water are important to prevent HEV infection. There is no vaccine specifically for HEV; however, the HAV vaccine is believed to provide some protection against it. Hepatitis E is the hepatitis virus that is typically self-resolving but can be fatal in pregnant women. While Hepatitis A and Hepatitis B can also affect pregnant women, Hepatitis E is particularly associated with an increased risk of severe outcomes, including fulminant hepatitis, during pregnancy. The severity of Hepatitis E in pregnant women is higher, especially in the third trimester, and can lead to increased rates of mortality. It is important for pregnant women to seek medical attention promptly if they experience symptoms of hepatitis or if there is a potential exposure to the virus.
