Liver abscesses caused by bacteria are generally not contagious, but amoebic liver abscesses caused by amoebas can be transmitted from person to person. Liver abscess is an infectious disease that occurs when the liver is infected by bacteria or amoeba protozoa, resulting in localized tissue destruction and suppuration. Bacterial liver abscesses are more common, and are mainly caused by biliary tract infections such as biliary roundworms, bile duct stones and other complications of septic cholangitis, and biliary tract infections are the main cause of bacterial liver abscesses. Infections in other parts of the body such as pyogenic osteomyelitis can also infect the liver through the bloodstream. Amebic liver abscesses that infect the bile duct can infect the liver through the blood, lymph, or directly through the intestines. When the feces of infected people contaminate water and vegetables, the liver can be infected through the bloodstream, lymph, or directly through the intestines. Eating contaminated water or vegetables can also be contagious, which can lead to person-to-person transmission. Among the chills, fever, vomiting, abdominal pain, etc. are symptoms of liver abscess, once there is a history of biliary tract infection or infection of amoeba plus the above symptoms, go to the hospital as soon as possible, so as not to delay the condition.
