Hepatitis E is inflammation of the liver caused by infection with the hepatitis E virus (HEV); [ 4 ][ 5 ] it is a type of viral hepatitis. [ 6 ] Hepatitis E has mainly a fecal-oral transmission route that is similar to hepatitis A, although the viruses are unrelated. [ 7 ][ 8 ][ 9 ] HEV is a positive-sense, single-stranded, nonenveloped, RNA ...
Orthohepevirus A. The hepatitis E virus (HEV) is the causative agent of hepatitis E. It is of the species Orthohepevirus A.[a][2][1] Globally, approximately 939 million corresponding to 1 in 8 individuals have ever experienced HEV infection. About 15–110 million individuals have recent or ongoing HEV infection. [3]
Hepatitis. Alcoholic hepatitis as seen with a microscope, showing fatty changes (white circles), remnants of dead liver cells, and Mallory bodies (twisted-rope shaped inclusions within some liver cells). (H&E stain) Specialty. Infectious disease, gastroenterology, hepatology. Symptoms.
Hepatitis C virus (HCV) can cause acute and chronic infections that are a major cause of hepatocellular carcinoma (HCC), advanced hepatic fibrosis and cirrhosis. [citation needed] HCC is a major cause of death in patients with chronic HCV infection. Regarding the pathogenesis of HCC associated with HCV, that virus may play direct or indirect roles.
Transmission of hepadnaviruses. The transmission of hepadnaviruses between their natural hosts, humans, non-human primates, and birds, including intra-species host transmission and cross-species transmission, is a topic of study in virology. Hepadnaviruses are a family of viruses that can cause liver infections in humans and animals.
Viral hepatitis (hepatitis B virus)—saliva, venereal fluids. (Note: hepatitis A and hepatitis E are transmitted via the fecal–oral route; hepatitis C is rarely sexually transmittable, [50] and the route of transmission of hepatitis D (only if infected with B) is uncertain, but may include sexual transmission. [51] [52] [53])
Amoebic hepatic abscess. Gross pathology of liver containing amoebic abscess. Specialty. Infectious diseases. A amoebic liver abscess is a type of liver abscess caused by amebiasis. [1] It is the involvement of liver tissue by trophozoites of the organism Entamoeba histolytica and of its abscess due to necrosis.
Pathogen transmission. In medicine, public health, and biology, transmission is the passing of a pathogen causing communicable disease from an infected host individual or group to a particular individual or group, regardless of whether the other individual was previously infected. [1] The term strictly refers to the transmission of ...
