B17.2
Acute hepatitis E
Clinical Classification Guidelines
Medical Intelligence & Overview
Acute hepatitis E is a viral infection that causes inflammation of the liver. It is caused by the hepatitis E virus (HEV) and is often transmitted through the ingestion of contaminated water or food. Although usually self-limited, it can sometimes lead to severe health issues, especially in pregnant women and individuals with existing liver conditions. Recognized under ICD-10 code B17.2, this illness primarily affects populations in regions with inadequate sanitation and water quality.
Causes & Symptoms
Clinical Causes: Infection with the hepatitis E virus (HEV), primarily transmitted through fecal-oral routes. Consuming contaminated drinking water or food, particularly in areas with poor sanitation. Exposure to sewage or contaminated water sources. In rare cases, transmission through blood transfusions or organ transplants.
Key Symptoms: Fatigue and weakness Loss of appetite Nausea and vomiting Abdominal pain, especially in the upper right area Dark urine Clay-colored stools Yellowing of the skin and eyes (jaundice) Fever Mild to moderate joint pain
Diagnostic & Treatment
Diagnosis Path: Diagnosis of acute hepatitis E involves a combination of medical history, physical examination, and laboratory tests. Blood tests are used to detect antibodies against HEV and the presence of viral RNA. Liver function tests may reveal elevated enzymes, indicating liver inflammation. In some cases, additional testing such as imaging or liver biopsy is performed to rule out other causes of liver damage.
Treatment Protocols: There is no specific antiviral treatment for hepatitis E. Management primarily focuses on supportive care, which includes maintaining adequate hydration and nutrition. Most people recover without complications within a few weeks. Severe cases, particularly in pregnant women, may require hospitalization and closer medical monitoring. Prevention strategies involve safe drinking water, proper sanitation, and good personal hygiene practices to reduce the risk of infection.
