Final answer:
Chronic hepatitis C is treated with antiviral medications and combination treatments. Lifestyle changes are also important in preventing transmission.
Step-by-step explanation:
Chronic hepatitis C can be treated with antiviral medications, specifically interferon alpha 2b and antivirals like lamivudine, entecavir, adefovir, and telbivudine. Combination treatments are commonly used, such as interferon combined with other treatments and protease inhibitors. In severe cases, liver transplants may be necessary.
It is important to note that hepatitis C does not have a vaccine available, unlike hepatitis A and B. Therefore, lifestyle changes like avoiding high-risk behaviors such as sharing needles or engaging in unprotected sex are also essential in preventing the transmission and progression of chronic hepatitis C.
