VIRAL HEPATITIS TYPE A, B, C, D, E AND F - Coggle Diagram
VIRAL HEPATITIS TYPE A, B, C, D, E AND F
-
Hepatitis A
-
-
-
-
clinical picture
fever, malaise, anorexia, nausea, abdominal pain, jaundice, and hepatomegaly.
-
Hepatitis B
can range from asymptomatic (subclinical, especially in neonates and children) to acute hepatitis to fulminant hepatitis (in less than 1%)
Clinical picture
flu-like symptoms or may have jaundice; may also be expressed in tiredness, fatigue, nausea or vomiting, dark-colored urine, fever, and chills
etiology
-
transmitted from person to person through blood, semen, or other body fluids. It is not spread by sneezing or coughing.
-
Hepatitis C
Injury to hepatocytes is caused by the direct cytotoxic action of HCV and damage mediated by T lymphocytes.
Clinical picture
tiredness, asthenia (fatigue); nausea or vomiting; fever and chills; dark colored urine; lighter colored stool; yellow eyes and skin (jaundice); pain in the right side of the upper abdomen that may radiate to the back; blood clotting problems; digestive bleeding (vomiting blood or black stool); bloating with fluid inside the abdomen (ascites).
Etiology
-
The infection spreads when blood contaminated with the virus enters the bloodstream of an uninfected person.
Hepatitis D
It is a defective, RNA-type virus that only replicates in hosts that are simultaneously infected by hepatitis B virus
Clinical picture
In case of superinfection of an asymptomatic HBsAg carrier, the picture presents as an intercurrent non-A non-B hepatitis and in chronic hepatitis B carriers as an exacerbation of
-
diagnostic methods
It is performed with a blood test in which the presence of HBV infection (defined by the positivity of the surface antigen) and anti-delta antibodies is determined.
Hepatitis E
-
-
The virus is excreted in the feces of infected people and enters the human body through the intestine.
Clinical picture
-
-
hyporexia, abdominal discomfort and fever
diagnostic methods
The disease can be detected by analysis of stool, serum or liver with techniques only available to research laboratories.
-
Hepatitis F
In developed countries, approximately 4 to 5% of acquired hepatitis do not have a specific viral etiology and the existence of other producing agents is assumed.
Clinical picture
It is indistinguishable from other known hepatitis and there is currently no epidemiological pattern or high-risk group identified
