Hi . This is an excellent question with no specific easy answer. The short answer is that HIV doesn't survive long outside the human body. The longer answer is that how long it survives can depend on multiple factors, such as temperature, environmental factors (like humidity and sunlight), the amount of virus in the fluid, and other factors. This article goes into further detail on this issue, including how factors outside the body impact the virus: https://www.healthline.com/health/how-long-does-hiv-live-outside-the-body. Hope this information is helpful. Best, Richard (Team Member)
