Hi there, i want to ask something regarding how actually HIV infect somebody, for example there are 4 cases that I wanted to ask whether that each cases able to infect HIV to us or not:
1. When you go to gym, and you didn't realize that your back just pricked by something that you don't know when you lay down in the bench. But, when you check in that bench there no such thing that prick you. Then, when you check the back area that got prick, there are little bit red colored skin around that area. However, you cannot see it clearly whether it is bleeding or not but it didn't feel any pain though. Does that situation can indicate someone could get infected from that situation?
2. Assume the condition quite same with number 1, you didn't know about what thing that pricked you. However, the back area that got pricked by a thing and got bleeding from it. Does that can make you infected by HIV? Since we don't know how that thing prick us whether into bloodstream or not...
3. Assume that condition quite same with number 1 too, but there is something small but sharp thing in that bench and you got pricked from it in your back. Which result your back are bleeding. Does that able to make you infected from it? Also, do you able got infected, when you got pricked by that something sharp in the area of your back that currently already had open wound before got pricked?
4. Assume that when you go to the gym but with open wound in your hand/ finger/ in any part of your body. You do your workout as usual,but with that open wound not covered by band aid or something. Does that able to get you infected by HIV if those open wound get contact with sweat or saliva of someone with HIV in that gym from touching the gym equipment or bench that contained with sweat or saliva of HIV person?
Please answers sequentially, to avoid any further questions and misunderstanding.
Your answers are very much appreciated.
Thank you.
