Hepatitis What Causes Hepatitis

Hepatitis is characterized by the destruction of a number of liver cells and the presence of inflammatory cells in the liver tissu.



 Hepatitis A, B, and C  
A person can develop hepatitis if they contract one of the viruses that can cause liver inflammation, or as a result of exposure to substances that can cause hepatitis.

The word hepatitis simply means an inflammation of the liver without pinpointing a specific cause. Someone with hepatitis may:
  • have one of several disorders, including viral or bacterial infection of the liver
  • have a liver injury caused by a toxin (poison)
  • have liver damage caused by interruption of the organ's normal blood supply
  • be experiencing an attack by his or her own immune system through an autoimmune disorder
  • have experienced trauma to the abdomen in the area of the liver
Hepatitis B
Hepatitis B (also called serum hepatitis) is caused by the hepatitis B virus (HBV). HBV can cause a wide spectrum of symptoms ranging from general malaise to chronic liver disease that can lead to liver cancer.

HBV spreads through:

  • infected body fluids, such as blood, saliva, semen, vaginal fluids, tears, and urine
  • a contaminated blood transfusion (uncommon in the United States)
  • shared contaminated needles or syringes for injecting drugs
  • sexual activity with an HBV-infected person
  • transmission from HBV-infected mothers to their newborn babies
Hepatitis C
The hepatitis C virus (HCV) is spread by direct contact with an infected person's blood.

The hepatitis C virus can be spread by:

  • sharing drug needles
  • getting a tattoo or body piercing with unsterilized tools
  • blood transfusions
  • transmission from mother to newborn
  • sexual contact (although this is less common)
Signs and Symptoms

Hepatitis, in its early stages, may cause flu-like symptoms, including:

  • malaise (a general ill feeling)
  • fever
  • muscle aches
  • loss of appetite
  • nausea
  • vomiting
  • diarrhea
  • jaundice (a yellowing of the skin and whites of the eyes)
 Hepatitis A, hepatitis B, and hepatitis C are all contagious.
