Hepatitis C is a type of viral hepatitis that is contracted by the blood route. Common routes of infection include the use of untested blood products (this occurred before the early 1990s), traumatic cosmetic procedures (such as tattoos, eyebrow tattoos, eyeliner, ear piercing, etc.), sharing of syringes, and unclean sex. Hepatitis C infection progresses slowly and insidiously after infection, often without obvious discomfort, and many patients are diagnosed only after 5 or even 10 years of infection when mild abnormalities in liver function are found by chance and further search for the cause, and a few patients find out they have hepatitis C infection only when they know they have cirrhosis. Hepatitis C is one of the few viral diseases that can be cured, and the treatment regimen commonly used in China is “pegylated interferon combined with ribavirin” for 24-48 weeks, with varying degrees of support from local health insurance for the treatment of hepatitis C. The key to detecting hepatitis C infection in a timely manner is screening, and those who have experienced the above are advised to go to the hospital for anti-HCV testing, and if found to be positive, HCV RNA quantification should be checked.
