What characteristic is notable about most Hepatitis C infections?

Most Hepatitis C infections are notably characterized by a high likelihood of progressing to a chronic infection. This means that after the initial infection, which may or may not present symptoms, many individuals will continue to carry the virus for a prolonged period, often leading to chronic hepatitis C. It's important to understand that although some people may clear the virus spontaneously within the first six months, the majority (approximately 70-80%) will go on to develop chronic hepatitis C. Chronic infection can have significant health implications, including the risk of liver disease, cirrhosis, and hepatocellular carcinoma over time.

By contrast, Hepatitis C infections are typically asymptomatic during the acute phase, making it challenging to diagnose early. Additionally, while chronic infection can occur at any age, it is more prevalent in individuals who were exposed during the 1960s through the 1980s when blood screening was less rigorous. Thus, few infections are restricted to older adults specifically; rather, it spans a broad age range among those at risk.
