So apparently I was called here as an expert on the topic of HIV? I don't know what's going on here, but HIV is not a very resilient virus and requires a specific set of conditions to survive in. They rapidly become unviable as infectious agents once outside of a host body as contact with other substances will change the pH of the fluid that HIV is residing in because they must stay between a pH of 7-8. However, HIV is resilient to low temperatures, and reliable killing only achieved at 60C. From what I know the longest HIV can survive in most rare case conditions such as syringes and dead bodies being 1 week for syringes and 2 weeks for dead bodies.
