I go to the toilet and have a habit of using a spray on the anus. If there is blood on the spray holes, I risk hiv infection
Thank you for your inquiry. From what we gather from the question, you were asking about your risk of HIV acquisition from using a toilet (specifically a bidet) if there is blood on the spray hole.
From the information given, this scenario is determined to be No Risk: (transmission of HIV is not possible in the given scenario). HIV is not transmitted through social or casual contact such as: hugging, kissing, shaking hands, sharing toilette or dishes (1). Although you may have noticed blood or other fluid on the 'spray hole', HIV does not survive long outside the body (such as on surfaces) and cannot reproduce outside the host (2). In your scenario, using a toilet that has potentially previously encountered blood may provide No Risk of HIV transmission, due to HIV being rendered inactive when exposed to environmental surfaces (such as a toilet spray).
Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions.
All the best,
AIDS Vancouver Helpline/Online, Cody
