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.
E) Hepatitis E
- 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.
G) Hepatitis G
- Newest strain of hepatitis and very little is known about it.
- Transmission is believed to occur through blood.

- These are mostly common and noticeable in IV drug users, individuals with clotting disorders such as hemophilia, and individuals who require hemodialysis for renal failure.
- Often hepatitis G shows no clinical symptoms.
