Hepatitis is an inflammation of the liver that results in liver cell damage and destruction.
Hepatitis D is a form of hepatitis that can occur only in the presence of hepatitis B. If an individual has hepatitis B and does not show symptoms, or shows very mild symptoms, infection with hepatitis D can put that person at risk for liver failure and liver cancer that progresses rapidly. Hepatitis D can occur at the same time as the initial infection with B, or it may show up much later as a new super infection. Transmission of hepatitis D occurs the same way as hepatitis B, except the transmission from mother to baby is less common. Hepatitis D is curable with treatment in about 15 percent of patients.
