Part of the show Exploring Hepatitis C
Dali Waverider, Second Life asked:
How many classes of hepatitis virus are there and how are they different?
We put this to Graeme Alexander:
Graeme - Well a lot of viruses can affect the liver, but thereís five that we recognize as important in the liver and they're HepatitisA, B, C, D, and E - rather imaginative arenít we?
The most important thing about hepatitis C is that it, by and large causes an infection that lasts for a lifetime while the other viruses don't (usually). So that differentiates it quite easily. And itís an RNA virus whereas hepatitis B is a DNA virus infection. But thatís sort of a semantic difference. The important thing about hepatitis C is that it causes lifelong infection in many people.
