She would have disposed of the syringe in the sharps container.Don't worry about this.You never had a risk.HIV can't survive in hot or cold conditions outside the body,those stories you here about HIV being frozen & then melted & be infectious again is a load of bull.
Thanks for your quick reply! I just worry the ice box and hollow needle make the living condition for HIV virus like in lab.
According to the reply, If there is no blood in the syringe, it is not a risk , even with reused needle, is that right?
Sorry , I just mean if the needle is reused, because I did not check the needle issue, and the nurse was doing some thing at the same moment.
