Patient: Couple weekends ago and this past weekend I took a drag off of a cigarette of one of my friends. I then just now found out she has undetectable HIV. This morning I woke up a pain in my upper chest ecerytime I take a deep breath. And I have a stuffy nose and swollen lymph nodes. Am I coming down with a cold or could I have got it from her ?

Doctor: Thanks for your question.HIV does not spread through casual contact and you cannot catch it by sharing a cigarette.Hope this helps
