Hepatitis is a "retrovirus" just like HIV. Retroviruses, as far as I understand, alter their genetic coding like the twists of a rubic's cube between generations, which is why it's so very tricky to make vaccines against them. Like HIV hep C is transmitted most "effectively" via blood-to-blood contact (hence the connexion with IV drug abuse). Unlike HIV, the hep C viruses are extremely hardy and are thought to be able to survive for months outside the body.
In the minds of the general public it's "dirty" (used) needles that spread such infections. In actuality hepatitis is said to be more likely spread via shared spoons. The microscopic viruses pass from the end of a reused needle into the drug solution and from here find their way into the myriad micro-scratches that lace the bowl of any drugs spoon, no matter how "new". It's here, in these scratches that hep C is thought to congregate and pass on and on...
... it is also suspected that hepatitis C can spread via used tourniquets (that could have micro-scabs all over them, even if they look clean) and other shared drug paraphernalia, including the citric acid or vitamin C European heroin users add to the mix to break down brown Afghan heroin.
In most cases hep C remains asymptomatic most of the time. When symptoms do manifest, they tend to be along the lines of constant fatigue, "brain fog", run-down-ness and depression. A very similar picture to the chronic fatigue syndrome I got diagnosed with over 15 years ago. So I really don't want hep C on top...
In a smaller number of cases, about 10-20% hep C leads on to severe liver damage and cirrhosis. In a smaller percentage, about 5% liver cancer results.
I know someone who is walking around today with less than half of his original liver as cancer ate a chunk out of it and surgeons cut a chunk more. He's the only person I know who's had interferon combination therapy to kill of the virus ~ and it worked! None of this is anything you'd go through voluntarily. After weekly "therapy" he said he could barely get out of bed for the first four days...
I basically don't want the test...
