What is more risky in hepatitis A B C?

Answer 1

This is not a simple risk assessment to do, there are actually 5 kinds of viral hepatitis (not just 3) and each has different means of transmission, prognosis, and treatment.

1. hepatitis A, food & water born, low mortality (4/1000 average rising to 17.5/1000 over age 50), bed rest and good diet avoiding fats
2. hepatitis B, blood or body fluids (e.g. sexual contact), very low mortality but significant increase in rate of liver cancers, usually no treatment needed except in <1% where antiviral drugs are needed
3. hepatitis C, blood born, cirrhosis as high as 15% carcinoma as high as 4%/year, interferon and antiviral drugs with liver transplant surgery in cases of cirrhosis
4. hepatitis D, blood or body fluids (can only occur with hepatitis B), very high mortality (200/1000), no reliable treatment interferon may or may not help
5. hepatitis E, food & water born, major cause of death in the developing world, supportive care

Some like A & E spread easily and rapidly, but only D which is much harder to spread has a very high mortality. Except for C & D only simple supportive treatment is required in most cases (and D has no known reliable treatment anyway but can be prevented by vaccinating for B). Liver cancers are a possibility with B & C.
