HIV transmission is quite complex. Several factors need to be met, with the most important one being that the bleeding person would have to be HIV positive. Their viral load would also have to be high enough to be capable of infecting the recipient – meaning they would have to be untreated, as treated individuals usually have a negligible viral load. Additionally, the blood would need to come into contact with a mucous membrane or an open wound.
Typically, such transmission occurs in cases like car accidents, where an HIV-positive person is bleeding heavily, and their blood enters an open wound of another person.
If you believe your flu-like symptoms could be related to an infection, you can already take a test – if the symptoms were related, the test would likely be reactive by now. However, the best approach is to take a test at least two months after the potential risk, with three months being the most reliable window.
