<s>[INST] Could you please help me by answering this question: how long can HIV survive in a tooth brush? I used a clean- looking tooth brush in a hotel room and my gum bled ( because of my Gingivitis). My boyfriend and I always use condom everytime. Can I get HIV? [/INST] Thanks for your query, I have gone through your query. The HIV can survive for 1-3min. Its very temperature sensitive and outside blood or liquid it will not survive. There are very fewer chances of getting infection. Unless your boyfriend is HIV positive and if there is any break in your oral cavity you can get infected. If the brush is contaminated with blood from a HIV infected person and if the same brush is used in another person, if that person has any break in the mucosa then he can get infected. I hope my answer will help you, take care. </s>
