Bloodborne Transmission
Hepatitis C virus is primarily spread through blood-to-blood contact. This includes sharing needles among drug users or receiving contaminated blood transfusions. Bloodborne transmission is the most efficient way for the virus to spread.
Other Transmission Routes
While bloodborne transmission is common, the virus can also spread through less direct means. Unprotected sex, especially among men who have sex with men, poses a risk. Rarely, the virus spreads through shared personal hygiene items.
Health Care-Associated Spread
Infections in health care settings occur through breaches in infection control, like improper needle use. Although rare, these incidents highlight the importance of strict hygiene practices in medical environments.
