I'm terrified that I might have gotten HIV thru a needle. I was helping this child fix her safety pin, but it pricked me twice on my finger. I ddin't see any blood come out, even though I squeezed it. But, it left two scab-like marks the next ay. Can Igt HIV from this safety pin incident, assuming the child or anyone else had it and I came in contact with infeted fluids on it?
