B16.9

Clinical Causes: Transmission through contact with infected blood or bodily fluids Sharing needles or syringes with someone who is infected Unprotected sexual contact with an infected person Receiving contaminated blood products or organ transplants Mother-to-child transmission during childbirth (less common in the context of acute cases) Contact with contaminated medical or tattooing equipment

Key Symptoms: Fatigue and weakness Loss of appetite Nausea and vomiting Abdominal pain, particularly in the upper right quadrant where the liver is located Dark urine Pale-colored stools Fever Jaundice (yellowing of the skin and eyes) Muscle or joint pain Mild to severe symptoms that develop gradually over weeks

Diagnosis Path: Diagnosing acute hepatitis B involves blood tests to detect the presence of hepatitis B surface antigen (HBsAg), hepatitis B core antibody (Anti-HBc), and other markers indicating active infection. Liver function tests may show elevated levels of liver enzymes like ALT and AST, reflecting liver inflammation. In some cases, additional tests such as hepatitis B DNA PCR can quantify the viral load. A clinician will evaluate symptoms, medical history, and laboratory results to confirm the diagnosis and rule out other causes of hepatitis.

Treatment Protocols: Management of acute hepatitis B primarily focuses on supportive care to help alleviate symptoms and promote liver recovery. There is currently no specific antiviral treatment for uncomplicated acute hepatitis B; instead, healthcare providers recommend rest, adequate hydration, and proper nutrition. Severe cases may require specialized medical intervention, including hospitalization and close monitoring of liver function. Most individuals recover fully within a few months, developing immunity to future infections. Preventative measures such as vaccination are crucial in reducing the risk of infection, especially for vulnerable populations.
