The average risk of transmission via needle-stick is:
1 in 3 for Hep B
1 in 30 for Hep C
1 in 300 for HIV
There is protection for Hep B, and HIV has no longevity outside the body... but Hep C... 1 in 30... over the course of a lifetime? There will come a time when EVERYONE has a yearly check for this insidious condition... and in my opinion that time can't come soon enough, but for now, you are in the medical profession, if it was me, I'd be tested every year.
being a nursing student makes you one in the risk groups so you should test periodically for blood borne diseases , i don't think that u can transfer hcv from this needle stick.
