SVR is the closest you'll get to "a cure" for hepatitis. Sustained virologic response, or SVR, is the goal of hep C treatment. SOC (a combination of interferon and ribavirin) doesn't necessarily eliminate the hepatitis C virus from your liver. It can, however, suppress the virus to undetectable levels for an extended period of time. In clinical language, this is called a "sustained virologic response," or sustained response. It means that during the six months after you complete treatment, there is no detectable hepatitis C virus in your blood.
SVR is a good thing. Studies have shown that with a six-month SVR (which means no detectable virus in your blood for six months after finishing treatment), relapse occurred in only 1-2% of patients. So, for every 100 people who finished treatment and attained SVR, the virus will return in only 2 of them. However, for these people, the virus never really left. The medicine was able to eliminate most of the virus (so much that medical tests couldn't detect it), but after treatment ended, for whatever reason the virus was able to continue replicating itself. The virus canalso return when people reinfect themselves (ie return to iv drug use)
I disagree though that the natural progression for everyone with hep c is cirrhosis & possible liver faiure. Only 20% of people diagnosed will go on to get cirrhosis, the rest will have varying amounts of liver damage, unfortunalty it is impossible to predict who will progress to cirrhosis so it is best that everyone who has a diagnosis of Hep C undergo treatment to eliminate the virus.
Lots of things should come into play when deciding to treat.
Do you work? - work & treatment can be very hard!
Are you at a healthy weight? - A healthy BMI is optimal for treatment
Have you been tested for Insulin Resistance? - IR has been shown to lower chances of achieving SVR.
Age? - younger age has better odds of clearing the virus
It is a very personal decision deciding to treat and no one can tell you either way which is better (wait for new treatments or jump in now). What I would do though is learn as much as you can about the virus so that you can advocate for yourself when meeting with treatment professionals.
