Hello, I went to the hospital yesterday to draw blood. When the nurse stopped bleeding for me, my pinhole was still bleeding. The nurse took out the iodophor cotton swab from the cotton swab box to wipe the pinhole for me. If this cotton swab was covered with the blood of AIDS patients and then pressed on my wound, would you like to know if it could be infected. Because I'm afraid that people with AIDS will retaliate against the society and inject a tube of their own blood into the box of cotton swabs, which will lead to the pollution of all the iodophor cotton swabs in the box, so I use the cotton swabs with blood, will it infect AIDS? If not, why? Do I need a test?
