If you have undergone any of the above procedures in countries where screening for hepatitis C and other blood-borne infections is not routine, you should make an appointment to talk to your doctor.
Injected drug use is a common method of hepatitis C transmission. Anyone who has ever shared a needle or syringe, or anything used to prepare the drug, could have been exposed to the hepatitis C virus.3

Transmission can occur when equipment contaminated with the virus is used during any procedure where the skin is broken. This can be a problem in the developing world where resources are limited and syringes are often re-used. Transmission of the hepatitis C virus has been known to occur through:1,3
The virus can pass from mother to baby during pregnancy. Around 5% of women with hepatitis C will transmit the virus to their child.5
