Doctor, I went in for an HIV test two weeks ago. The results are non-reactive. However, now I am worried because exactly 2 weeks later, I have an itchy throat which is now a cough. Also had mild fever for a day. Could these be ARS symptoms? What is the risk of getting infected if the clinic that I went to reused a needle? I know that this does not happen on purpose but what if a used needle was used by accident? I've been reading some of the posts on this forum and I've seen responses that say that sharing needles is a risk for getting infected. Again, I know that this does not happen on purpose but what if it happens by accident? Also, if there's no risk for getting infected this way, then why are medical practitioners advised to get PEP in case of a needlestick injury? Please answer my questions. I will really appreciate it.
