Dear Expert,
I was get blood dwawing at CDC in shanghai, china. I did not see the whole procedure of the doctor open a new injector. I was worrying if the injector does not clean. But at that morning, 4 of the people all shows negative. is it possible that the doctor hide a needle with high concentration of HIV virus?
after that, I have been checked again for 27 days and 34 days, can I be get rid of getting infected with HIV?
does the window for needle sharing be more longer than sexual infected?
