Why do people on this site always say no risk from open wounds?

"Some healthcare workers have become infected after being stuck with needles containing HIV-infected blood or, less frequently, when infected blood comes in contact with a worker's open cut or is splashed into a worker's eyes or inside their nose. There has been only one instance of patients being infected by an HIV-infected dentist"

You've been given your assessment, so move along.

I still don't understand how you can definitively say there is no risk.

Question on CDC website:

Has anyone been infected with HIV from a needle stick injury out side a medical care setting:

No. While it is possible to get infected with HIV if you are stuck with a needle that is contaminated with HIV, there are no documented cases of transmission outside of a health-care setting.

You touched blood...you had no risk!

I understand that the answers will not change, I just don't understand why this is such a good site and yet it contradicts other credible sites.

We don't debate information on other websites. Your situation was no risk. The answers on this forum will not change.
