What is a significant risk factor for Hepatitis C transmission?

The significant risk factor for Hepatitis C transmission is blood transfusions. This virus is primarily spread through direct contact with infected blood. Before the implementation of rigorous screening processes for blood donors, transfusions were a common way for individuals to contract Hepatitis C. While the risk of transmission through blood transfusions has dramatically decreased due to enhanced screening measures, it remains a critical point of transmission for the virus.

Use of shared needles among intravenous drug users and occupational exposure in healthcare settings also pose significant risks for transmission. However, when considering general public health and historical data, blood transfusions stand out as a primary vector for Hepatitis C spread. Other transmission methods, such as sharing personal items or close contact, do have some association with the virus, but are not as significant as blood exposure routes.
