Question

Quizplus · Accepted Answer

In developed countries, the most common risk factor for hepatitis C virus infection is intravenous drug abuse, particularly when needles are shared among users. This is because the hepatitis C virus can be easily transmitted through exposure to infected blood.  Blood transfusions were previously a major risk factor, but improved screening methods have significantly reduced the risk of contracting hepatitis C virus from blood transfusions. Unprotected sex and perinatal transmission are also possible modes of transmission, but they are less common. Mosquito bites are not a risk factor for hepatitis C virus transmission.
