Viral hepatitis, when liver function is significantly abnormal and during acute bouts of illness, may result in some patients experiencing mild or high fever, which is transient. Common symptoms include fatigue, aversion to oils, nausea, abdominal bloating, and poor appetite. Clinical symptoms vary among different types of viral hepatitis. Common types include Hepatitis A, B, C, D, and E. Hepatitis A and E are acute self-limited forms of hepatitis, which generally recover within four to eight weeks. Hepatitis B and C, however, can easily become chronic.
