HIV is a virus that has the ability to impair the immune system. The medical world has learned a lot about how the virus may and cannot be transmitted during the past few decades since it first emerged.
The idea that HIV may spread through blood or pee on a toilet seat has been debunked. This article demonstrates why it is untrue.
According to research
Human immunodeficiency virus, or HIV, is typically transmitted through various bodily fluids. Your bloodstream must come into intimate contact with the virus for infection to take place. Although there are a number of methods in which transmission might happen, a toilet seat is not one of them.
Despite the fact that HIV can persist in a person, it cannot endure long periods of time in the air or on solid surfaces. The Centers for Disease Control and Prevention (CDC)  state that once HIV leaves a person, it almost instantly becomes completely inactive.
The only way to catch HIV from a toilet seat would be if you had an open wound or an exposed mucous membrane through which the bodily fluid on the seat might enter your body. The mouth, rectum, and genitalia all have mucous membranes.
Hard surfaces should be cleaned using standard cleaning techniques, which are also employed in healthcare facilities, rather than using specific sterilization processes.
