Which condition is Hepatitis C primarily caused by?

Hepatitis C is primarily caused by direct contact with human blood. This viral infection is transmitted when the blood of an infected person enters the bloodstream of an uninfected person. Common routes of transmission include sharing needles or other drug-injection equipment, being born to an infected mother, or receiving contaminated blood products before the implementation of rigorous screening processes.

Understanding the transmission routes of Hepatitis C is crucial for prevention and control, especially in fields where there's potential exposure to blood, such as criminal justice. This condition is not spread through food or airborne means, which explains why other options are not relevant to the primary cause of Hepatitis C. Genetic factors do not contribute to the spread of Hepatitis C; rather, they may affect an individual's susceptibility to the disease or progress of infection once contracted.
