Can a drop of someone else's blood going inside my ears cause hiv or hep because there was blood on their hand and while talking the blood from there hand splashed into my ears. It was fresh. Can their blood mix with my blood going inside the ear? I am really worried. Where does the blood go if it goes inside our ear? Does it reach out blood stream? Can it cause hiv or hep? Please answer all of my questions here. That will give me a peace of mind. Because I am really scared and worried about the blood going inside my ears.
