What is the most likely virus responsible for this patient’s disease based on this graph? A 27-year-old female sex worker presents to a free clinic complaining of tea-colored urine and clay-colored stools. Patient history reveals a recent trip to Mexico and non-specific systemic symptoms such as fatigue, nausea, and low-grade fever. She admits to alcohol and intravenous drug abuse. Physical examination reveals epigastric discomfort and yellow-tinged sclerae. Blood work shows elevated aminotransferase concentrations, but normal alkaline phosphatase levels. The following graph depicts the progression of this patient’s disease:
A. Hepatitis A virus B. Hepatitis B virus C. Hepatitis C virus D. Hepatitis E virus
The correct answer is option B The woman most likely has Hepatitis B. The graph depicts the progress of hepatitis B. From the history we can tell that this woman is a sex worker who admits to use of intravenous drugs. Hepatitis B is most common transferred through sexual intercourse and through parenteral means (through blood). Fatigue, low grade fever and nausea are common signs and symptoms of Hepatitis. Hepatitis A is most likely not the case as Hepatitis A is not a chronic infection and thus does not last for a long period of time as depicted on the graph.
