Acute common hepatitis caused by virus A (or benign) is the most common form (90% of cases). It is jaundice or jaundice. The disease often begins with a week of various disorders: arthralgia, headache, anorexia, nausea, abdominal pain, urticaria. Then jaundice appears, of varying intensity, often pruriginous. Urines are rare and dark. The fatigue is important. The evolution is favorable in 2 to 6 weeks although the fatigue can persist a few months. In some cases, jaundice is very mild or absent: it is anicteric hepatitis whose diagnosis is not always easy.

Viral hepatitis: additional examinations and analyzes

The liver test shows:

  • Elevation of transaminases SGPT, SGOT (ASAT and ALAT);
  • The increase of bilirubin with predominantly conjugate;
  • The moderate increase in alkaline phosphatase ;
  • A slight decrease in Prothrombin (PT);
  • Serologies and PCR are requested depending on the context.


In the vast majority of cases, the evolution is favorable. A polyuria announces the progressive disappearance of jaundice. Anorexia and vomiting cause significant weight loss.
