Which of the hepatitis prevalent in pregnancy ?
**Core Concept**
Hepatitis in pregnancy is a significant concern due to its potential impact on both maternal and fetal health. The hepatitis viruses prevalent in pregnancy are primarily hepatitis B (HBV) and hepatitis C (HCV), with hepatitis E (HEV) also posing a risk, particularly in endemic regions.
**Why the Correct Answer is Right**
Hepatitis B is the most common cause of hepatitis in pregnancy, transmitted vertically from mother to child during delivery. The risk of transmission is higher if the mother is a chronic carrier of HBV, with a seropositive status for hepatitis B surface antigen (HBsAg). Hepatitis C, while less common, can also be transmitted vertically, although the risk is lower compared to HBV. Hepatitis E, typically a self-limiting disease in immunocompetent individuals, can have a more severe outcome in pregnant women, particularly in the third trimester.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because hepatitis D (HDV) is a rare cause of hepatitis in pregnancy, and its transmission dynamics differ from those of HBV and HCV.
**Option B:** This option is incorrect because hepatitis A (HAV) is primarily a self-limiting disease and is not typically associated with vertical transmission in pregnancy.
**Option C:** This option is incorrect because hepatitis G (HGV) is a relatively rare and poorly understood virus, and its role in hepatitis in pregnancy is not well established.
**Clinical Pearl / High-Yield Fact**
In regions where hepatitis E is endemic, pregnant women should be advised to practice good hygiene and avoid consuming undercooked meat, especially pork, to reduce their risk of infection.
**Correct Answer: A. Hepatitis B.**
