”Hepatitis C” is an abbreviation for the medical name “viral hepatitis C”. It is a disease caused by a person infected with the hepatitis C virus (HCV) and is mostly chronic in nature. A random survey found that a surprising 61% of the public did not know about hepatitis C. Only 29% of the public knew the name of hepatitis C, and very few knew about its harmful effects on the human body. From a medical point of view, hepatitis C is a disease that is more likely to lead to cirrhosis than hepatitis B. It must be taken seriously. The hepatitis C virus has a hidden route of transmission and is currently mainly transmitted through the bloodstream. When the hepatitis C virus enters the body, the incubation period in the human body can be up to 20 weeks, and because of the long incubation period and the slow development of the disease, 80% of patients with acute hepatitis C have no obvious symptoms, and more than 70% of new cases are completely asymptomatic. Other data show that between 50% and 85% of people with acute hepatitis C evolve into chronic hepatitis C. After the next 20 or 30 years, these chronic hepatitis C patients can silently develop cirrhosis or even liver cancer. As a result, it is often overlooked, and many patients are found out during physical exams or during visits for other diseases, and some even find out only when they have advanced cirrhosis or liver cancer visits, missing the best time to treat them. The hepatitis C virus damages the body by directly damaging liver cells. Given the special nature of hepatitis C, the medical opinion is that once hepatitis C virus is found to be replicating, it is best to get antiviral treatment as early as possible to prevent cirrhosis and liver cancer, regardless of the liver function condition.
