1) no risk. Virus degrades quickly. It cant enter you from nowhere
2) virus doesnt live long outside host
3) no risk
You are the one who is paranoid. I am very angry. This is why the world have Heavy stigma for hiv. If hiv is spread as easily as you have said, everyone in the world would have gotten hiv.
You have absolutely no reason to be sorry for asking a simple question. NO one is mad at you other than one random poster so really, no worries. This is a forum to ask your questions and to educate people and all types of questions are welcome. So, please do not let that response deter you from asking things. Really, that IS the point of this forum.
So, HIV is a sexually transmitted disease The only way that someone gets HIV is from having unprotected vaginal or anal sex or sharing IV drug needles. That's really it. The doctors misspoke when they said 'low' risk as the risk is zero from the situation you describe. As stated, air inactivates the virus. Any blood you see has been exposed to air so is not going to have the virus in it. Hey, even if you had sex with the guy in the bed next to you, a one time sexual encounter has a low transmission rate of 1%. So, there is no worry about your risk of HIV from sharing this hospital room. This was a good question. I'm sure many wonder and in many places, hiv education is scarce.
Glad your colonoscopy results were clear.
Honestly, you literally have nothing to worry about. Nothing that you described is any risk for infection. As long as you didn't engage in unprotected anal or vaginal sex with this person and you didn't share needles to inject drugs into your veins, nothing else would lead to infection. You can share a room and a toilet and eating and drinking utensils with an HIV positive person and none of those will lead to infection. You're completely fine and have nothing at all to worry about.
Erm. The thing u need to know is that hiv is not spread that easily. Only through sex and needle. You shouldn't be worrying excessively.
