Hepatitis C is a viral infection that primarily affects the liver, leading to inflammation and potential liver damage. It is caused by the Hepatitis C virus (HCV), which is mainly spread through contact with infected blood. Common transmission methods include sharing needles, receiving contaminated blood products, and, less frequently, sexual contact. Many people with Hepatitis C may not show symptoms for years, making it difficult to diagnose early. If left untreated, it can lead to serious complications such as liver cirrhosis or liver cancer. Fortunately, effective treatments are available that can cure the infection in most cases.
