2. Blood Transfusions Before 1992
The likelihood of contracting hepatitis C through a blood transfusion nowadays is extremely low. In fact, it’s virtually impossible because now all donated blood is tested before it’s used. However, the year 1992 was when the screening test for HCV went into effect, says WebMD, so prior to that, using infected blood during transfusions was one reason behind new cases of HCV popping up in the United States. “People who had hemophilia, thalassemia, or other disease requiring multiple transfusions were especially at risk for exposure,” writes Very Well Health. Thus, any blood used for a transfusion prior to 1992 could potentially be infected and unintentionally transmitted to another person.
Very Well Health writes that experts believe the chance of getting hepatitis C through a blood transfusion is so rare that it’s about one in two million.
