Different types of viral Hepatitis

Types of hepatitis

A) Hepatitis A

  • It is the inflammation of liver from the hepatitis A virus.
  • HEA virus is generally found in the stools and blood of an infected person about 15- 45 days before symptoms occur and during the first week of illness.
  • Usually spread by fecal-oral contact, or fecal-infected food and water.
  • It is the least serious and mildest of these diseases.
  • The other hepatitis infections may become chronic illness but hepatitis A does not become chronic.

B) Hepatitis B

  • It is inflammation of the liver from the hepatitis B virus.
  • This virus has highest concentration in blood and in lower concentration in other body fluids like semen, vaginal secretions, and wound exudates.
  • Hepatitis B virus gets transmitted from one person to another through blood and body fluids exposure such as blood, semen, vaginal secretions, or saliva.
  • Infants may also develop the disease if they are born to a mother who has the virus.
  • It has a wide range of clinical presentations.
  • It may cause chronic hepatitis, can be mild, without symptoms and, in some cases, can lead to full blown liver failure and death.

C) Hepatitis C

  • It is the inflammation of liver by hepatitis C virus.
  • This virus can be found in body fluids, other than blood, including saliva, semen, menstrual fluid, spinal fluid, ascites fluid, and urine.
  • Hepatitis C is transmitted primarily from contact with infected blood, but can also transfer from sexual contact or from an infected mother to her baby.
  • The symptoms are mild and gradual in case of hepatitis C.
  • Children often show no symptoms at all. Though Hepatitis C has milder symptoms initially, it can lead to chronic liver disease in a majority of people who are infected.
  • Hepatitis C is the leading indication for liver transplantation.
  • People with alcoholic liver disease also tend to develop hepatitis C.

D) Hepatitis D

  • Also known as “delta hepatitis” caused by a virus called hepatitis D virus (HDV).
  • Only in the presence of hepatitis B, this form of hepatitis generally occurs..
  • The time of hepatitis D occurence is same as the initial infection with B or it may show up much later.
  • Hepatitis D can be transmitted in the same way as hepatitis B, except the transmission from mother to baby is less common.

  • This form of hepatitis is similar to hepatitis A which is caused by a virus called hepatitis E virus (HEV).
  • Transmission occurs through fecal-oral contamination.
  • It is less common than hepatitis A.
  • Hepatitis E is most common in poorly developed countries and rarely seen in the United States.
  • The prevalence is highest in East and south Asia.
