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.
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.
