No. This is inaccurate information and this was explained on your previous post. HIV is not transmitted this way. Air inactivates the virus. HIV doesn't "hide in your body for days". The ONLY ways that adults get HIV (as already explained) are from having unprotected vaginal or anal penetrating sex or sharing IV drug needles. No, using a razor blade of someone with hiv would NOT transmit the disease, air is present. Surfaces can not give you hiv. I am sensing a lot of anxious thinking on your part. Please focus on the ways that someone actually can get hiv, unprotected vaginal or anal sex or sharing IV drug needles and as long as you don't do that, you do not need to worry about hiv.
Please throw that book in the garbage. I am not sure where did you get a book that is giving you such foolish information.
Below are the only risk for transmission:
1. Unprotected vaginal or anal intercourse.
2. Sharing needle with people who inject drugs.
