Hepatitis is an inflammation of the liver usually caused by a viral infection. It is known under several names, depending on the type of hepatitis. These are: A, B, C, D, E and G. The first three are the most common.
Hepatitis can be transmitted through: transfusions, sexual secretions, fecal contaminated foods, etc. or it can be caused by viruses, alcohol, drugs, tumors, etc.
Causes of hepatitis are:
- Also, hepatitis type A and E are caused by the ingestion of contaminated food or water. They can also be taken by direct contact with infected persons and do not leave carriers once cured (persons able to transmit the disease).
- Hepatitis B, C, and D are transmitted through contact with infected body secretions, such as through transfusions of contaminated blood or blood products, sharing infected materials such as syringes, medical equipment, etc. Type B hepatitis can also be transmitted from mother to child at birth or through sexual contact. The most common types of hepatitis are those of type B and C, which cause chronic pathology and are the most common cause of liver cirrhosis and liver cancer. Inflammation can occur from the following causes: drugs, alcohol, toxic chemicals, poisonous fungi, etc.
- Besides these types of hepatitis, there is also a more unusual type of hepatitis, which is called chronic active hepatitis. This type affects generally affecting women but in rare cases men. Chronic active hepatitis is an autoimmune disease, which is associated with certain genes, with symptoms similar to other forms of hepatitis and with progressive evolution towards cirrhosis.
