The hepatitis B virus has an unusual feature similar to retroviruses. This makes it deadly and difficult to treat when it is at an advanced stage. It basically attacks the liver and can cause both an acute and persistent infection.
In the acute stage, the cells are newly attacked and the body is fighting it off, the symptoms might start showing depending on how long it has invaded the body. These symptoms include dark urine, vomiting, yellowing of the skin and eyes (jaundice), the liver can still fail at this stage causing death.
At the persistent stage, which is already chronic, the invaded cells have been weakened, the symptoms are slow to resolve therefore it is in a prolonged stage which can lead to liver cancer and eventual death.
