Hcv can spread by hemodialysis machines?

Blood transfer: Potential risks could be from re-use of needles, tubing, or dialysis cartitrdies/membranes. Other risks would be related sanitary behavior: not changing gloves and washing hands inbetween machines or patients; touching machines/paperwork with gloves on after touching patient. All of these require the transfer of hcv+ blood from one patient to another.

Tiny amounts blood: Even very small amount of blood from someone who has hepatitis c can spread this infection. So in dialysis units, improper cleaning of surfaces that might have been contaminated with blood could be an issue, as is using multi-use vials of medicines for multiple patients. If health workers use universal precautions the risk to patients is low.
