Types of Hepatitis

Types of hepatitis


Hepatitis A
Usually transmitted through food or personal contact. The incubation period (the infection until the appearance of the symptoms) is about a month. Generally symptoms last for two months.  It is a mild infection and the infection is cleared spontaneously. There are vaccines available.

Hepatitis B
Primarily transmitted through either sexual contact or exposure to infectious blood.  There are vaccines available. The virus can lie undetected in the liver for up to 20 or 30 years. It can lead to cirrhosis, liver cancer and even death. Treatment is available, although in the majority of cases it can be cured spontaneously. The available drugs cannot clear the infection, but reduce the dangers of damage to the liver, thus making it possible to live with the disease, with treatment of it for varying periods of time.

Hepatitis C
the largest epidemic of humanity today, five times more widespread than the AIDS / HIV… The infection is carried by blood through transfusions, dentists, shared syringes, etc. . . . It is not transmitted by sex unless there is mutual bleeding) There is no vaccine available. There are various subdivisions of its virus (genotype 1, 2 and 3 and the rare 4, 5 and 6). There are approximately 200 million people in the world who are carrying the hepatitis C virus.

Hepatitis C is a leading cause of liver transplant, accounting for 40 % of cases. It can cause cirrhosis, liver cancer and death.

Hepatitis D
The infection caused by the hepatitis D virus (HDV) occurs only in patients already infected with hepatitis B. In patients chronically infected with the Hepatitis B virus, the effects of this together with HDV accelerate the progression of chronic disease.

Vaccination against Hepatitis B also protects people against an infection from Hepatitis D.

Hepatitis E
It is caused by the hepatitis E virus (HEV) and transmitted via fecal-oral transmission, principally by contaminated water , causing major epidemics in certain regions (notably in South and East Asia) .

Hepatitis E does not become chronic. However, pregnant women who were infected with hepatitis E virus may have more severe forms of the disease. The disease is self-limiting and usually lasts only 4 to 6 weeks.

Fortunately proper hygienic habits and better control of the quality of the water used by individuals may avoid contact with this virus.

Hepatitis F
Recent reports have shown that the identification of hepatitis F (VHF) cannot be confirmed, so this type of hepatitis can be disregarded.

Hepatitis G
the hepatitis G virus (HGV), also known as GBV- C is transmitted through blood and is common among intravenous drug users and transfusion recipients.

The G virus can also be transmitted during pregnancy and sexual contact. It is often found in co-infection with other viruses, such as Hepatitis C virus (HCV), Hepatitis B virus (HBV) and AIDS (HIV).
